Charging calculator Plan a slow charge before you plug in. Pick a car and the battery levels, then ask one of three things: how long the charge will take, which current to set on the charger, or how far you will get in the time you have. The calculation uses your car's battery capacity and can allow for wear, based on the battery health estimate built from your own sessions. Set your car's onboard charger power and the calculator will cap the figure accordingly, so a 22 kW charge point will not promise you a speed your car cannot accept. It also shows when the charge will finish, and says tomorrow when it runs past midnight. Working out a charge for someone else's car? Pick Other car and type the battery in by hand. Nothing is saved. The calculator covers AC charging only. DC fast charging slows down along the charge curve, and an honest estimate is not possible from the data the app has. Indonesian Rupiah Now in the currency list. Under the hood Updated libraries.

My Trips Pick the charges from a road trip and save it as a report you can come back to any time. Each trip shows distance, energy, cost, consumption per 100 km and how much you saved compared to a petrol car. Share it as an image in one tap. Custom date range Sessions and Statistics now let you pick any two dates instead of only the preset periods. More accurate mileage Distance for a selected period is now counted from your last charge before that period, so nothing gets lost at the edges. Trip reports count only the distance driven during the trip itself. Smoother charging entry The kWh limit now allows for charging losses, so you can enter the real figure shown on the charger. The app is also smaller and starts faster.

This release is a major accuracy upgrade for energy and cost tracking. PRECISE CONSUMPTION WITH BATTERY % • kWh/100 km now uses the gap between battery % before/after a trip — partial charges no longer inflate the number. Charging 20% after using 7% used to show 34 kWh/100 km; now Volti shows the real ~12. • Reports display an "Approximate" badge when most sessions miss battery %, so you always know how reliable the average is. • Cost per km uses the same accurate math — Cost per 100 km finally matches "consumption × tariff". NEW "DISTANCE TRACKED" STAT See how many kilometres your average is computed from. "12 kWh/100 km on 1,200 km" is real signal. NEW "MONTHLY COST PER 100 KM" CHART Spot seasonal price changes and how winter driving hits your wallet, broken down by month. FASTER BATTERY % ENTRY Tap a preset chip: 0/10/20/50 for "before", 80/90/100 for "after". Single tap, done. Same chips in the session editor and Quick Apply template dialog. SMARTER EMPTY STATES • First session for a car? Card now shows "first charge" instead of a confusing dash. • If only your battery % is missing, you'll see a gentle "Fill battery % →" prompt that opens that session for editing. • If the missing data is elsewhere (previous session, no battery capacity), we won't badger you. BATTERY CAPACITY IS NOW REQUIRED On a new car, capacity becomes mandatory — precise consumption can't be computed without it. Existing cars without capacity show a friendly warning chip with one-tap fix. SINGAPORE DOLLAR ADDED Singapore EV drivers, welcome! Switch to SGD in Settings → Currency. BEHIND THE SCENES • 18 new unit tests cover the consumption methodology so future updates can't break the math. • Methodology documented in code for transparency. Got an idea or found a bug?

This release polishes the home-screen widget and adds a metric you've asked for. Highlights: • Widget redesign — smooth teal gradient background and a car icon tinted with the colour of your default vehicle. At a glance you know whose totals you're looking at. • Widget now shows average consumption (kWh / 100 km) and cost per 100 km for the current month, alongside kWh and total cost. • Reports → Efficiency — new "Cost per 100 km" row next to "Cost per km". Useful for comparing with your old petrol or diesel car (e.g. 6.40 EUR / 100 km vs the 12–14 EUR you used to spend). • Under the bonnet — ad mediation upgrade for a steadier fill rate, deprecated-API cleanup and dependency upgrades to keep the app ready for the next iOS release. Thanks for tracking your EV charging with Volti! As always, the app stays offline-first — no account, no cloud sync of your sessions. If you spot anything off or want a feature, drop a note from Settings → About.

This update reworks how currency is handled and polishes a lot of rough edges. What's new: One currency for the whole app - pick it once in Settings, it applies everywhere. No more mismatched totals. Smarter kWh entry - the input is capped by your car's battery capacity, so a stray zero can't turn a 50 kWh charge into 500. Templates are tighter - a tariff is now required, and the charge type (AC/DC) follows the tariff automatically. Sessions screen - the summary block smoothly hides as you scroll down for more list room, and comes back when you scroll up. Auto-capitalize on every name field (car, tariff, template, location). iOS fixes - CSV import now opens the file picker properly on iOS 13+, and the cursor no longer jumps to the start while typing. Cleaner native ads - proper dark mode, no clipped text, no empty icon slots. Teal-themed templates list and menus across the app. App version in Settings now shows the actually installed version. Thanks for tracking your charging with Volti!

What's new in version 1.1 • Currency per car — each car now stores its own currency. New cars auto-detect it from your device locale. Pick from 30+ currencies with a single tap. • Smarter totals — when sessions span multiple currencies, total cost is no longer mixed; only same-currency totals are summed. • Templates polish — the quick-log dialog validates kWh and odometer as you type, shows the last reading as a hint, and uses the app's teal accent. • Reports — Day / Week / Month / Year selector no longer wraps text on narrow screens. • Session editor — battery % before/after fields are now stacked full-width so labels stay on one line. • Template editor — tap outside a field to dismiss the keyboard; Save button stays visible when the keyboard is open. • Updated Apple Privacy Manifest for App Store compliance. • Various small UI fixes and improvements.
