There are definitely some improvements that could be made
My main complaints are:
1) When you are adding your day light circle settings (ex. 50% brightness from 8am - 10 am) each subsequent setting is dependent on the end time of the one right before it. So if you have 3 settings (8-10, 10-12, 12-2) and you want to change the first setting go end at 11 instead of 10, you have to delete all of the later-in-the-day settings before it will let you adjust the earlier one.
2) When you make your daylight circle, you are limited to 6 different settings that it will cycle through for the day. That’s honestly enough, but it doesn’t indicate that until after you have added the 6th. This is super annoying considering my first issue (above) because you can only edit the timing of the latest-in-the-day setting. So when you find out that the 6th one you added is the last one you can add, and that schedule doesn’t cover the full day, you have to delete everything and start over.
3) My final issue is specific to the “Blue White Flat One +” but the color temperature graph is backwards on the Daylight Cycle chart. So full white with no blue on the actual light shows as dark blue on the graph (and vise versa). It doesn’t have that problem with the “Yellow White” version of the light.
So overall, because I rarely have to use the app, and once you understand its quirks it does serve its purpose (even if it’s a little frustrating) I’m giving it 3/5 start. Mostly because the light itself is really nice
