The problem

Most drivers keep their maintenance history in a folder of paper invoices, if at all. Existing apps such as iGarage only work when your garage is connected: without it, the app is empty. The driver depends on whether the garage takes part.

The idea

Let the driver start on their own. Take a photo of the garage invoice and Wrenchly reads the date, garage, mileage and costs. You check it before anything is saved. Your history grows by itself, and you see what is coming next: APK, service, tyres.

Design & build

One maintenance visit is the unit: date, garage and mileage once, with multiple items inside. A calm dark interface with one mint accent, built on my own design system in Figma. I built the iOS app myself with React Native and Supabase, using Claude Code as my development partner.

Privacy by default

No ads and no selling of data. Accounts and invoices are stored in the EU, and one button deletes everything, files included. The app is now in TestFlight on its way to the App Store.
