Mix metric and imperial. Settings › Units › Choose each unit sets temperature, speed, tyre pressure, fuel and the rest one at a time: °C with mph, litres with psi. Metric and Imperial still set them all at once, and nothing you have saved changes, only how it reads. Ride height, wheelbase and track width. A setup's Geometry sets the ride height and the wheelbase, front and rear, as positions from the chassis's centre, a step at a time, and the front and rear track width in millimetres. The rear axle. A setup's Geometry records the rear axle: standard, short or a length you type, and its stiffness letter, H, N, Q, S or U.

Check your jetting. For every engine the calculator covers, the main jet, clip position and air screw now come from the density of the air: temperature, pressure and humidity together. Put your engine through the calculator again and check the numbers against the ones in your notebook. Set the venturi on your setup. On a Rotax Pre-EVO, a setup's Jetting section holds the venturi, 8.5 or 12.5, with the needle and the floats, and the jetting calculator works from them. Next up on Home. Once Start here is done, Home suggests one thing to do next: the jetting for a race day in the next three days, a race day to plan, your tyre sets, or on Pro your first session. And bug fixes.

Laps on every tyre set. Tyre sets count laps beside their heat cycles: tap + beside Laps on a set's card, or on the kart's mounted tyres for front and rear at once — and − takes laps back off. The tyres under every session. A telemetry import asks “Which tyres were on the kart?”, with their laps and heat cycles before the session, and can add the session's laps and a heat cycle to them. “Setup and tyres” on a session changes either afterwards. (Pro) Lap times by tyre age. On a set's card, see every timed lap against how far the set had run: how many laps it needs to come up to pace, its best lap and when, and the pace it loses per 10 laps. (Pro) Sessions by day. Switch the Telemetry list to “By day”, and narrow it to one track, or one day, from Filters. (Pro) What you changed between sessions. Compare two laps from different sessions, and “Setup changes” at the end shows what you changed on the kart in between: pressures, gearing, jetting. It covers sessions imported from now on. (Pro) And bug fixes.

Import straight from a MyChron. Join your MyChron 5's Wi-Fi, tap Import session and choose “From a MyChron”: the logger's own sessions are listed by day with their best lap. Tick the ones you want, or “Select day” for a day's timed runs, and they import together — the kart and engine time asked once, each track saved once. No computer in between. (Pro) And bug fixes.

See how you drove each corner. Tap a corner under “Where the time is” and it opens on its own page, its stretch drawn on the map, to show how each lap drove it: the hardest braking, where it came off the brake and where it got back on the power. The reasons name what cost the time — coasting before braking, staying on the brake longer, a slowest point that came late — each with something to try. With RPM on a kart without a gearbox, it also shows rear lock-up and wheelspin. (Pro) Every corner across the session: switch “Where the time is” to Every lap for what an ordinary lap gives away in each corner against your best there, how much that varies, and which lap did it best. The lap table marks warm-up and off-pace laps, and a likely tow. (Pro) Revs and gearing from your file: the revs at each corner's slowest point, where the engine pulls hardest on your own straights, and how close the straights come to the limit. On a kart without a gearbox, it estimates whether a tooth more or fewer on the rear would be quicker — something to test next session. (Pro) And bug fixes.

See where each lap lost time. Open a session and, under the map, “Where the time is” names the corners that lap lost time in, costliest first — how much, and whether it went through the slowest point, slowing for the corner or on the straight after. Tap one and the map and the chart zoom onto it, mark where each lap started slowing and its slowest speed, and say what to try. In Compare laps, two laps get a bar for every corner, measured at the same places on the track. (Pro) Back up the whole garage: every kart, the spares on your shelf, tyre sets, gear, events, shopping, routines and telemetry go into one file. Restore it on your next phone — restoring doesn't need Pro. Compare two setups side by side on a kart's Presets tab, and see only the settings that differ. (Pro) With Imperial chosen in Settings, tyre pressures read in psi, speeds in mph and rollout, chain and geometry in inches — on the setup sheet, in the tools and in telemetry. Tap a tyre pressure or a sprocket and type the figure straight off your gauge. And bug fixes.

KartGarage may now ask what you think of it: rarely, never in your first days, and only right after something has worked — a setup applied, a session looked over, the last job on a kart ticked off. A rating or a few words on the App Store helps other kart racers find the app.

ROUTINES The checklist your mechanic keeps, grouped by when you do it: on arrival, before every session, after a wet session, after the last race. Make the groups your own, drag them into your order, tick them through the weekend kart by kart, clear the ones you mark for the next run, and send the lot to whoever is helping you. WRITE DOWN A ONE-OFF REPAIR A cracked side pod or a sheared screw goes on the kart's maintenance list as a one-off repair, with no interval to invent — and a new job starts as a repair, so writing one down takes a name and nothing else. THE KART SHOWS WHAT IT IS BEHIND ON A kart's card in the garage and its maintenance row count the jobs waiting on it, not only the parts that are worn. Swipe a job to the right to tick it off. TELEMETRY IN YOUR UNITS Speed, distance and altitude on every session, chart and comparison follow the units you chose in Settings: mph, feet and miles, or km/h and metres. HOURS-BASED JOBS SAY WHEN THEY ARE DUE A task that runs on engine hours shows the meter reading it is due at and the hours run since it was last done. It turns overdue on the kart, on Lists and on Home once that reading passes, and a job written down without a completion measures from the meter as it read that day. EVERY SESSION AND EVENT NAMES ITS KART A telemetry session, an event and a kart's own telemetry list all say which kart they belong to, so two karts under one tent stay apart. With one kart in the garage, a shopping line goes on that kart. KARTGARAGE IN TURKISH Türkçe joins the eight languages the app speaks. Pick it in Settings, or let the phone's language choose. BUG FIXES - A full tyre set mounted over a front and a rear pair takes both off, and the dialog names every set it replaces. - A part demounted to Inventory keeps its hours when it is fitted again. - A new tyre set with no cycles on it is not listed under Needs attention. - Correcting the engine meter down while keeping part wear never records a negative install reading. - A kart the form cannot fully resolve can still be renamed. - The jetting calculator opens with the kart tile whole and Calculate always in reach. - Opening another tab from Home slides in like any other screen, and a swipe from the left edge follows your finger back. - The add-task sheet keeps Save in reach with the keyboard up, and the interval boxes let go of the keypad.

FULL-SCREEN CHART, TWO LAPS AT ONCE Tap the expand button above a session's chart and the map and chart take the whole screen. Pick any channel, then "Pick a lap" to lay a second lap over the first — from the same session or another day at the same track: the gap in seconds sits beside the readout, red where the lap you are looking at is behind and green where it is ahead, and the gap itself can be the trace. The figures above the map now belong to the lap you selected, with "Whole session" one tap away, and the lap picker scrolls through as many laps as you recorded. Pro. RECEIVED THE MOMENT IT ARRIVES A shopping line can be marked received as soon as it arrives, whether or not you want it on the shelf. "Add to inventory" is a separate step: offered when you mark the line received, always in the line's menu, and available for a whole selection at once. Each card now shows the one step its line is waiting for. The shelf is called Inventory everywhere in the app. EVENTS: PLACES YOU ALREADY KNOW The location field suggests your saved tracks, the places from earlier events and anywhere on the map as you type. Every event card has its own menu, so you can edit or delete an event without opening it, and a newly saved event opens straight onto its checklist. JETTING ON HOME A Jetting tile sits on Home beside Telemetry and opens the calculator in one tap. The shortcut tiles are solid colour now, and "Customise" still lets you put them in any order. TYRES AT A GLANCE Heat cycles are counted with a stepper right on the tyre card, Mount is the filled button, and a mounted set wears a badge naming the kart it is on. Tyre rows on small phones show the whole compound name. BUG FIXES - Pro switches off when your subscription ends. - Deleting a kart removes everything that belonged to it, and the dialog lists what goes. - The free limits are shown with their numbers. - An error while saving or deleting reads as a plain sentence in your language, and dates follow your language's format. - Lists refresh on their own after a change. - A maintenance interval in hours can be typed with a decimal point. - Faster start after an update.

JETTING FOR A TRACK YOU HAVE NOT REACHED YET The calculator only ever asked what the weather is here, now. Name the circuit instead — search it, or drop a pin on the map — and the hour you will be on track, and it works the jetting out for there and then. Useful the night before, when the van is half packed and the meeting is three hours away. ONE ANSWER INSTEAD OF TWO CARDS The main jet and the spark plug come out of the same air, so they are one block now rather than two cards a screen apart, with the conditions they assume printed beside them and the confidence figure above. Apply to Setup says what it is about to overwrite before you tap it. THE SAFETY NOTICE STAYS The jetting notice could be dismissed permanently, and nothing anywhere brought it back. It is part of the screen now, on every tab, and it opens the full text along with the two warnings that used to be buried — lean running, and what too hot a plug does to a piston. There is also a copy in Settings under Legal. SEND THE RESULT Share on the jetting result sends the fitment to whoever is holding the spanner: engine, carb, jet, plug, needle and clip, with the conditions it was worked out for. Plain text, so it lands readable in any chat, and the safety line travels with it. HOME SHORTCUTS YOU ARRANGE The shortcuts are squares now, each showing the one figure worth a glance — days to the next race, parts overdue, lines still to buy. Telemetry leads. Drag them into the order you want from the Customise tile. TELEMETRY AND SETUP Sector times sit in columns under S1, S2 and S3, and the fastest sector of the session is purple the way a timing screen has always said it. On the gearing graph, the same ratio on the next front sprocket up or down is spelled out, with a way straight into the equivalence tool. SHOPPING Share sends what you are looking at to whoever is ordering; tap Select on a group heading to send only part of it. A line can hold a link to the listing you chose. The In warehouse group starts folded, and the free limit counts only what you still have to buy. NOW IN EIGHT LANGUAGES KartGarage is translated into Italian, French, Spanish, Portuguese, German and Dutch, alongside English and Polish. It follows your phone, or you can pick a language of your own in Settings. FIXES • Rotax DD2 Pre-EVO: any carb build other than the default was given the leanest main jet in the range, and a clip three positions lean with it. Corrected. If you run a DD2 Pre-EVO, check the numbers against what you were given before. • A named place now brings its altitude with it, instead of leaving your own. • The keyboard no longer covers the field you are typing in on the place, engine, carburettor and part pickers. • Photos taken in landscape are no longer squashed into a square. • Backing out of a screen opened from Home animates instead of jumping. • Tapping a card's ⋮ on Lists no longer pages the hub to the next tab. • Polish: the preset summary and the overdue count are translated rather than printed as stored English.

TELEMETRY: YOUR LAP TIMER, IN THE GARAGE Import a session and see where the time actually went. • AiM XRK, Unipro UNI/TSV, RaceBox CSV and GPX • Every lap timed from GPS, with best lap, consistency, top speed, max RPM and max head temp • Place the start line and the splits on the track map, then read sector times off it • Save a track once and everything you log there is timed against the same line, so the lap times stay comparable • Compare two laps. The track turns red where the slower one lost time and green where it gained, and the app names the worst stretch • Draw speed, RPM, head temp, cornering g, braking g or altitude along the lap, with a cursor that reads out the value at any point • Every session carries the setup that was on the kart and the weather it was run in, looked up for that place and hour • Add the session's running time to the kart's engine hours if you want it, measured from RPM rather than off the clock • Sessions group by circuit, and each heading carries that circuit's best lap Telemetry import and lap analysis are part of Pro. Nothing that was free before has changed. GO AND FIND THE PART Shopping items now know which part they are, so KartGarage writes the search phrase and takes you to it online: a web search when you have a part number, or the kart racing parts category on the marketplace. A MANUAL, NOT A TOUR The one-off walkthrough is gone. In its place is a guide you can reopen and search any time: how the app fits together, step by step for the jobs that cross several screens, and a glossary of the words this app uses in its own way. HOURS AND MINUTES, TYPED PROPERLY Engine and wear time is a plain hours + minutes pair everywhere now, and the keyboard can finally type the format it shows. Every text field also has a way to put the keyboard away again. A LIGHT THEME THAT HOLDS UP OUTDOORS Status colours, labels and cards were reworked for daylight, so the app stays readable at the circuit. Wear bars now move when the number behind them changes, so adding engine time shows its consequences instead of just a different screen. Reduce Motion turns that off. FIXES • Completing an hours-based maintenance job now restarts its hours clock, not just its date. Before this, a job set to "every 20 hours" read as fine forever once you had done it once. • Buying Pro from the prompt now carries out the action that asked for it, instead of dropping it. • The Wet filter searched the weather text for rain, so it hid Snow and Thunderstorm. Every weather condition is now translated as well. • Stock and Telemetry filter from one panel that stays put, instead of one that scrolled away or hid itself with a filter still applied. • Compare picks a lap by session instead of scrolling a wall of text.

A NEW TOOLS TAB The Calculator tab is now Tools, and the jetting calculator has company: • Sprockets & speed — ratio, rollout, top speed and a speed-vs-rear-sprocket curve, per engine. KZ gearboxes draw every gear; the DD2 lists all seven legal gear pairs. • Chain length — links for a sprocket pair at your real centre distance • Sprocket equivalence — match a ratio using only the sprockets you own • Fuel mix — oil for a tank at your ratio, with the makers' published figures Every tool reopens on your last values, and you can enter your own rear rolling circumference so every speed on screen follows the tyre you actually run. A SPARK PLUG ADVISOR The jetting result now recommends a heat range for the conditions, worked out from the same air density as the jet so the two can never disagree. Ladders come from the engine maker or the series — Rotax MAX EVO and pre-EVO, IAME X30, Vortex ROK — with Denso's iridium range alongside. Classes with no established figure get no guess. JETTING THAT READS THE AIR PROPERLY • Altitude now changes the answer. The calculator asks whether your pressure is a sea-level forecast figure or a reading taken at the track, because only one of them sets air density. • Humidity goes in as the pressure it physically is, instead of a flat multiplier that could swallow a jet size or invent one. • Clip position and air screw follow the same corrected pressure. • The hourly forecast names the plug alongside the jet. STOCK AND SHOPPING • Filter parts by All, In stock, Mounted or Worn out • Parts fitted to a kart are findable from Stock and tap through to that kart • Identical spares collapse behind a count instead of scrolling as unrelated cards • Long-press shopping items to select several and change their status at once • Tyre and gear photos load far faster FORMS THAT FIT ON A PHONE Add and edit sheets now ask for what makes the thing and fold the optional half — price, notes, photo — behind one row that names what is inside. The save button stays on screen with the keyboard up. FREE AND PRO The free tier now includes five jetting calculations a day. Adjusting a calculation you just ran is not charged as a new one. Setup presets past three per kart, saved tracks past the first, and the before-and-after comparison in setup history are Pro — your history itself is never hidden. FIXES • Gearing assumed a rear tyre larger than a kart rolls on, so every top speed read about nine per cent high • On a warm day the plug advisor jumped two heat ranges at once; IW29 is back on the ladder and NGK 9 now reads as IW27 • Back from a part opened out of Stock returns to Stock in one tap • Part wear is only asked for once you have typed an hour meter reading • Polish text filled in on the shopping cards and the tyre wear bar

RACE DAY EVENTS Plan a race weekend end to end. Create an event with its date, track, and kart, then build a packing checklist from your warehouse or with custom items. Watch your packed progress, add the event to your calendar, and share the checklist with your team. GEAR HOMOLOGATION Keep helmets, suits, gloves, boots, and rib protectors on file with their standard, homologation number, and validity dates. KartGarage warns you before anything expires — no more surprises at scrutineering. A REBUILT JETTING CALCULATOR • A step-by-step form that only asks for what it actually needs • Results split into Setup, Through the day, and Alternatives • Recommends clip position and air screw, not just the main jet • Support for Rotax DD2 and Pre-EVO carburetors • An hourly "jet through the day" forecast with per-parameter charts (Pro) • Set a reminder or a calendar entry for the hour your jet needs to change BACK UP AND MOVE A KART Export any kart as a JSON backup or a readable text report — setups, parts, history, maintenance, and photos included — and import it back on another device. A CLEANER LOOK Redesigned dark theme with a neutral, Apple-style palette, red accents by default, and consistent contrast everywhere. FIXES • Jetting no longer overcorrects for humidity • The cursor no longer jumps while typing weather values • Parts saved with a "None" reminder are handled correctly • Praga and Intrepid are now grouped under IPK • Fixed a crash when upgrading from a very early version of the app • Filled in missing Polish translations throughout Thanks for racing with us — feedback is always welcome.
