Every mod, every service, every dollar — one timeline per car.
Frequently asked
How do I sync my garage across devices?
On iPhone and iPad: sign in to iCloud on each device and make sure iCloud is enabled for Modbook. Your cars, mods, service records, and photos sync automatically through your private iCloud account — no separate login needed.
On Android there is no sync: your garage stays on the phone, and Android's backup to your Google Account covers it. Photos aren't in that backup; they move when you transfer straight to a new phone. iPhone and Android don't sync with each other, but Export CSV carries a car's history across.
Is my data private?
Yes. Everything stays on your device and in your own iCloud or Google backup. Modbook has no analytics or trackers, and the developer cannot see your data. See our Privacy Policy.
Does Modbook work for electric cars?
Yes. Set your car's powertrain to electric and Modbook adapts — battery and charging service tracking, and no oil-change reminders. Petrol, diesel, hybrid, and plug-in hybrid are all supported too.
What are dyno and Dragy runs?
Modbook logs both dyno pulls (power, torque, boost) and Dragy-style acceleration times (0–100, 100–200, quarter mile). Each run remembers which mods were installed when it was measured.
I deleted something by accident. Can I get it back?
Yes, for 30 days. In the Garage, open the ⋯ menu, choose Archive and tap Restore. On Android, the bar that appears right after you delete something also offers Undo.
