I've used this for many years, but it doesn't play well with my new watch so I'm moving on. I still love the alarm clock aspect, but the sleep tracking by my watch is so much more accurate. If there was a simpler version that only did the slow wakeup alarm I would 100% still use that, as I've not found anything else so far that does it as well.

Used to be a great app, but since the addition of the Programs feature in late June, it's been broken. The Sleep Aid doesn't work, and the daily journal shows zero info. I tried contacting the support email, but after telling them that I couldn't send the requested data due to a size limit for attachments in my email, I have received zero response. I am giving them till 8/15 to fix this, or else I'm canceling my subscription & finding another app. EDIT: Sent email as instructed & still no reply.

Love the idea. But this time around after buying a year, the watch companion app continues to go off between 6 and 630, sone sort of gentle wake feature. Can't remember what it's called. Despite me turning it off, and selecting ONLY 630, it continues to do it, and then will simply NOT dismiss until I turn OFF the watch. So continues to vibrate and wake more than just me. Very frustrating. I got rid of it this morning and cancelled a re-occuruing sub. I was at my wits end lol.
