Dipstick: Car Maintenance Log is a DIY vehicle maintenance log for iPhone, made by Bruce Labs. Log the work you do on your vehicles, keep your records in one place, and get reminders when maintenance may be due.

Questions, bugs, and ideas go to dipstick@brucelabs.io. I read every message myself and usually reply within a couple of days.
Managing or cancelling Dipstick Pro
Open iOS Settings → your Apple Account → Subscriptions, choose Dipstick, and tap Cancel Subscription. You keep Pro until the end of the period you've paid for. The lifetime purchase doesn't renew, so there's nothing to cancel. For refunds, go to reportaproblem.apple.com.
New iPhone or reinstall
Sign in with the same Apple Account and iCloud. Your records sync back from your private iCloud, and you can restore your Pro purchase in Dipstick.
Your data
Dipstick collects nothing. Your data stays on your iPhone and in your own private iCloud, and you can export or delete all of it in the app at any time.
