I made Good Time because I wanted a clock that actually helps you set a mechanical watch — one where you can see exactly when the second hand hits 12, down to a fraction of a second. • DIALS: Swipe through a variety of dials — field, dive, dress, chronograph, moonphase, etc. Light and dark versions. • CHRONOGRAPH: There's a stopwatch built in. You can run it with your volume buttons — up starts/pauses, down resets. • WORLD TIME: Search for a city and see what time it is there • 100% FREE: No in-app purchases, no subscriptions, no ads, and I'm not planning to add any. I'm not trying to make money off this — I just wanted it to exist. Made for the Grey Nato crew. If you have a request for new dials, let me know in a review.

Verdict
The clearest difference is update cadence: Good Time at every 3 days against Smart Flow Meter's every 3 weeks. Smart Flow Meter's advantage is device support (3 vs 1) and iOS requirement (11.0 vs 18.5). On price, ads and in-app purchases there is nothing between them.
