Hi everyone,
I recently made the jump and got a Bangle.js 2. I'm very much enjoying it so far, especially thanks to the community support and apps, so thanks to everyone who contributed! It has practically all of the features I require from a smartwatch: lightweight, always-on display, long battery life, checked grocery/to-do list, some health tracking features, sliding clock-inspired watch face, mini-games and smart sleep alarm. A more general purpose workout tracking app is lacking for me (with a real-time timer, heart rate monitor and step count, and a summary of the workout afterwards). Maybe I'll also contribute by making such an app but with my limited coding skills, I'm not sure if it'll be possible :S
More to the point, the smart sleep alarm (SleepPhaseAlarm or Sleep Log Alarm) particularly helped in my decision in getting the Bangle.js 2, as it is surprisingly rare to find on-device smart sleep alarms. Others like Sleep As Android require a companion phone app and drain battery. The only other smartwatches that I know have an on-device smart sleep alarm are TicWatch WearOS smartwatches. But as the Bangle.js 2 is more privacy focused, it's a more appropriate fit for me.
However, unless I am mistaken (please correct me if I am!), the SleepPhaseAlarm or Sleep Log Alarm app only wakes you up at a specific interval before your actual alarm (rather than at any time within a range). For example, if my alarm is set for 8am, either of the smart alarm app will wake me up at 7:30 if I set the earlier wake time for 30min before the actual alarm.
Other smart sleep alarm apps work differently as far as I know. If you set the smart wake-up interval for 30min, it will not wake you up at exactly 30min before the actual alarm. Rather, within 30min, the smart alarm will determine when you are in light sleep stage and will wake you up. This can be 30min, 17min or 6min before the actual alarm time. This makes sense to me as your sleep stage duration fluctuates and isn't necessarily 30min/20min/10min before your alarm.
As such, I wanted to request if it would be possible to have such a smart wake feature for the SleepPhaseAlarm (or Sleep Log Alarm) that would wake you up within a set interval, instead of a specific earlier time. If such a feature already exists and I am not aware, my apologies! I'd appreciate any clarifications in the app use in this case.
I hope that my request is clear and thanks for taking the time to read it!
