Tiiks vs Steed: Strava wear or an Apple Health log
Steed logs Apple Health rides on iOS, with no account. Tiiks applies Strava distance to each named part on iOS and Android.
Steed is a no-account maintenance log that lives on one iPhone. You import activities from Apple Health or type them, then assign each one to a bike. There is no sign-up, no data collection, and no server. Tiiks syncs Strava automatically and adds the distance to the named parts that were fitted. The split is private local storage versus an account that follows any phone.
The short version
If having no account and no data leaving the device matters, and the rides are already in Apple Health: Steed.
If you want Strava distance on named parts, without typing, on iOS and Android, with the record surviving a lost phone: Tiiks.
What Steed covers
The Bike Maintenance Log tracks chains, cassettes, tyres, pads, sealant, bleeds, and wax dates. You import rides from Apple Health or enter them by hand, then assign each one to a bike or a wheelset. There is no account. The data stays on the device. Widgets and extra bikes sit behind a paid tier. The app runs on iOS only. If the iPhone is lost and there is no backup, the wear record is gone.
What Tiiks covers
Tiiks does not import from Apple Health or allow manual ride entry. Strava rides land automatically on the chain, cassette, and tyres that were fitted, by their catalog names, with rider reviews on each model. The wear record sits on a login that works on iOS and Android. A new phone is not the end of the chain's history.
Can you use both?
You could, but they would count the same parts from the same rides. If privacy is why you use Steed, adding a Tiiks account removes that reason.
Does Steed sync with Strava?
No. Distance comes from Apple Health or from what you type.
