I bought my Apple Watch mainly to be able to look at my calendar, be notified when I need to go to a meeting, on my wrist. (Unreliable because of synch problems - but that's another post.) Unanticipated benefit: being able to collect quick items - To Dos, ideas, set appointments - easily, by voice, on my wrist. Q: what are the best watch apps people have found to do this? 0) Surprisingly, Apple's standard Notes app is not watch enabled. 1) Apple's Reminders app is watch enabled. It can be used voice-only - "Hey Siri, remind to to write up idea about cache coherency". Small problem in that it times out, so can only use for short notes. Bigger problem is that it can only be used when connected to cloud, which is unreliable in the canyon I live in. Biggest problem is that I have Reminders on my watch stopped synching with Reminders on my iPhone/iCloud two weeks ago. Apple Genius Bar guys unable to help.

Doesn't need to be connected - it will record a voice file, which you can have transcribed later. Plus, you have original voice recording to double check. Problem: not 100% voice controlled: I frequently find myself having to poke buttons on my watch with my nose. Problem: the process of requesting a transcription, and then moving the transcription to my main tracking system (in my case, OneNote) is onerous. 3) I just realized that Microsoft OneNote has a watch app. Transcribes directly to your OneNote Quick Notes section, saves work. Problem: not 100% voice controlled, so requires poking at the watch screen, with finger, or nose if hands are full. Problem: must be online to use. Q: what other "quickly collect items on your watch" options are there? Bonus points for 100% voice controlled, offline, records speech as well as transcription, and easy to transfer to other apps. -- Similar but different: I am into QS (Quantitative Self) - monitoring moods, etc., figuring out when I am working well and when I am not. I also likely "Hourly Chimes", at circa 5 minutes before the hour. I have tried various "Time Chime" apps, but the app that I have found works best for me so far does both QS and Time Chime: iMoodJournal. I have it pop up onto my wrist at 5 minutes before the hour during the work day, and prompt to record how I am feeling - Great/Good/Meh, etc. Tells me the time. iMoodJournal also allows you to speak a diary note. This isn't really what you want for a GTD-style collection app when an idea pops into your head. But it is similar. Problem: not 100% voice controlled. Problem: 6 taps to make a record. Problem: exporting not automated.
