Know your battery before it lets you down.
Hold your iPhone to your battery tester and watch the values fill in. BatterySnap follows your car battery’s health over time and tells you when it’s time for a new one.
Coming soon to the App StoreScan, don’t type
The tester’s screen is read live – voltage, cold cranking amps, health, charge and resistance appear as they are read. Works with the Foxwell BT705.
See the trend
Every value in one calm chart, and a replacement forecast once there is enough data – never a guess.
All your cars
Cars with plates, batteries with their dates, reminders to test, and the air temperature from Apple Weather with every test.
Private by design
Your data stays on your iPhone and in your own iCloud. No account, no ads, no tracking.
