[Beta Test] WatchOS Metronome App - Haptic Feedback

[supercruz]

Hello everyone, I'm excited to announce my metronome WatchOS app has been released for TestFlight!

If you have an apple watch and would like to participate,
here's invitation link: https://testflight.apple.com/join/KbBCFaSe

I would appreciate testers to answer these questions:

• Verify the metronome starts, by tapping the orange circle in the main view
• Verify the metronome continues to run, when your wrist is lowered
• Verify the metronome stops by tapping the orange circle after it has started or closing the app
• Verify the settings page change properties of the app by swiping to the right of the BPM view and interacting with the settings of the different categories

I would love to hear additional feedback:

• what you like
• what you don't like
• what should be added

Screenshots attached below

Thank you

The timing is not rock solid. When flicking around in the interface, it has to get caught up to deal with the interrupts. When I turn my arm, it again has to get caught up with the interrupts of movement. I don't see a way to make it run with just vibration, and not the beep. Otherwise good first step.

To disable sounds, put your watch into "Silent Mode": https://support.apple.com/en-us/108368# ... le%20Watch
I'm working on a solution to this.

Can you tell me about your setup:

• Which apple watch do you have?
• What OS is your watch running?

Still not rock solid on the time. If I wave my hand/arm for whatever reason, the timing goes off.
5/4 is not even generically steady, even if I hold my hand still.
The only time it’s steady is if I don’t move my hand at all, and the watch face is up, regardless of time signature.

Ultra 2, watchOS 11.6.1

I'm working on a fix for the timing un-steadiness. I'll report back when I have a new version for testing.

Thank you for trying the new version.

I don't have a physical Ultra 2 to re-create your setup. But when I run the app on my series 9 and wave my hand I notice the haptics are harder to notice.

Thank you for pointing this out, I'll see what I can do to improve this.
