Your battery health, while you charge. While you record at the charger, a line under the verdict now shows the battery health so far: a range worked out from the points you have committed. It is the same calculation as when you save, not a second number. As long as too little has been charged, the line says how much is still to go; if the charged kWh are missing, it tells you where to set them. Once you have saved charges, it also says whether the value fits your trend. An estimate with its range, not a measurement by a specialist workshop. Also in this version: • The wheels, the plus and the camera stay put while you record: at the bottom in portrait, beside the reading in landscape. When the verdict grows or the text is large, only the area above scrolls. The note on cell temperature sits behind "Why?". • New in the vehicle catalog, with France in mind: Peugeot e-208, e-2008 and e-3008, Renault Zoe, Mégane E-Tech and Scénic E-Tech, Dacia Spring, MG4, Fiat 500e and Nissan Leaf. BatCap now checks for new cars once a day when it opens and tells you in the garage what arrived. Without a connection, nothing happens.

See the battery report before you unlock it. Tapping the locked report now opens a sheet with a sample report straight away: a made-up sample vehicle, marked "SAMPLE" on every page and drawn by the very renderer that makes your PDF. Below it, the price, buy, restore and redeem a code. Your own report contains your own measurements, is an estimate with its range, and does not replace a measurement by a specialist workshop. Also in this version: • Buying a used EV? The empty garage now offers two ways in: check a file from the seller (free, offline) or a short guide to measuring on a test drive. One charge gives a range, not a verdict, and the guide says so. • The photo series from a charge is easier to find: its own row at the top of the form and on the recording's start sheet. Without Apple Intelligence you enter the values by hand, as before. • BatCap asks for a rating sooner, after the sixth charge with a result instead of the twelfth. Never at launch, at most once a year.

BatCap is now on the Apple Watch too. The recording at the charger starts on your wrist: start it, set the level, the power and the charged kWh with the Digital Crown, commit a point, finish. The charging curve with its expected corridor sits beside it, and the plus button takes the colour of the verdict for the value you have dialled. The iPhone stays the truth: it is the same recording, never a second one, and the closing form opens on the phone. Also in this version: • BatCap now speaks French too. The app follows the system language and can also be switched per app, from iOS's own language settings. • The recording has a third wheel: the charged kWh from the charging screen. One tap on the plus now commits three values. • The curve comparison has a fourth step: "Better than expected". Until now everything from 90 per cent of the reference upwards was called "In the expected range", twice as much included. • The three wheels turn in one direction: the same gesture raises the level and the kWh and lowers the power, the way a charge goes. • A quiet card at the top of the garage shows when a newer version of BatCap is on the App Store. It only appears when a newer version is actually known, and it is never a window in your way. • Appearance is now a choice: System, Light or Dark, for this app only, in Settings. • The level and power wheels now open on the correct value, instead of sitting briefly at zero.

"Record a charge" no longer means hunting for the app. BatCap ships two shortcuts: start the recording, and log a charging session afterwards. Both can be spoken to Siri, for instance "record a charge with BatCap", assigned to the Action button and built into your own shortcuts; the recording also has a button in Control Centre. You can name the vehicle when you ask, and if you do not, BatCap takes the last one. Nothing is logged on its own: the app opens the right screen, and you fill it in by hand, as always. Also in this version: • During the recording you feel what is being committed: a point set, an undo, the finish. • The wheels click into place, detent by detent. • The session form carries a save bar at the bottom that is still there after six sections. • The settings begin with language and data; the purchase sits behind the function. • The big numbers grow with the text size you have set.

Under the hood: a new purchase backend for the supporter purchases and the lifetime unlock — same promise as always: purchases stay anonymous and the app works fully offline. Plus small stability improvements.

The live recording has been rebuilt end to end — after real charges at real chargers. A committed point never changes again: the wheels set up the next point, plus commits it with the clock of now, and the preselection holds instead of running to 100 % while you fetch a coffee. A small switch beside the wheels controls auto-advance. The header shows symbols instead of words. The charge lives as a Live Activity on the lock screen and in the Dynamic Island: vehicle, last point, point count, elapsed time — and it honestly fades when your last reading grows old. AC charges are treated honestly: the power wheel opens at 11 kW at a wallbox instead of 150, and the curve comparison and point verdict stay silent — the reference curves are DC fast-charging curves, and behind an 11 kW line they would not be an expectation. On DC, the expected corridor now sits behind the recording: "am I in the band?" answers itself while you charge. A closing photo showing both kWh figures (car and charger) yields the measured efficiency of that charge — printed, never folded into the capacity. Sealed charge histories and backups open straight from Mail, Files and AirDrop — "Open in BatCap" is enough. Plus: a clearer date axis on the trend, a fold-out explanation on the warranty card, and many small fixes.

A sealed charging history — the reason for this update. Sealing a charge freezes it: it can no longer be edited, and it carries the time of an independent time server. Each seal holds the fingerprint of the one before it, so any later change to an earlier charge shows. The chain view prints, for every entry, how soon after the charge it was sealed, and a mark in the session list tells sealed charges from unsealed ones at a glance — tap it and seal from right there. When you sell the car, you hand the history over as a file. The buyer checks it free and offline, sees exactly what the check does and does not show, and can take the vehicle, chain and all, into their own BatCap. Nothing is ever re-signed: their first own charge is signed by their own key, and the chain prints the boundary at exactly that point. Also in this version: • Charge kind detected instead of guessed. Above 50 kW the app switches from AC to DC itself and says so; if you insist on AC, AC is what you keep. • The times of individual charging points can be corrected. A misread timestamp no longer means discarding the whole recording — and a time you set by hand stays marked as set by hand. • Reference data checked again. The three catalogue entries listed as weak were researched one by one: two confirmed, one corrected. The vehicle catalogue can also be updated from the web on your tap. • A tidier garage. One chevron per card instead of two, the seal mark sits beside the date, and the export rows are grouped in one place. • A small charging curve on every session card, with the expected corridor behind it.
