u/DevGerrOS

Hi r/WearOS! I'm a solo developer. This started as a Garmin app that a few hundred people use, and I've now ported it to Wear OS.

It turns your watch into a real speedometer. GPS measures your speed every second, and the needle moves smoothly instead of jumping between readings.

What it does:

- 10 dial designs that fill the round screen: Classic, Vintage, Halo, Neon, Panel and more. Turn the crown to switch.

- km/h, mph, knots or m/s. The scale adapts to your top speed or stays fixed.

- Trip stats: distance, moving time, average and top speed. Your top speed also stays on the dial as a marker.

- Speed alert: the watch vibrates once when you go over your limit, and the dial shows a red zone.

- Keeps running when the screen turns off, and stops by itself after 20 minutes without moving.

- A tile with your last ride and one tap to start.

Privacy: your location never leaves the watch. No account, no ads, no tracking.

It's €0.99 on Google Play: https://play.google.com/store/apps/details?id=app.gerros.speedometer

Good for cycling, sailing, skating, or just checking how fast that train is going. I'd love feedback, especially on which dial you like and what you'd add next.

Hey r/WearOS — I'm a solo dev and just released Caffi for Wear OS.

Most caffeine apps just add up milligrams. Caffi models how caffeine is actually absorbed and cleared by your body (a pharmacokinetic model), so it can show:

- how much caffeine is in your system right now

- a curve of the coming hours

- the time you're "sleep-ready" again

- your daily total vs. your limit, plus stats

There's a tile with a gauge, so you can see it with one swipe from your watch face. Logging a coffee takes two taps on the watch — no phone needed.

It's €0.99, no ads, no account, no tracking.

I'd love feedback — what's missing, what's annoying, what would make you use it daily?
