Thanks heaps for the response!

Regarding the RTC, I think I will try implement a sleep/low power mode when the battery drops below a certain point anyway, to preserve the data captured. No new data would be requested or read, so this shouldn't be an issue.

Thanks again, I think I have enough info now to commit to a TinyScreen+ for this project.

Hi,

I'm looking at making a wearable device which will prompt the user every 10mins (when awake) with a pager motor and record the users response. The response will be one of 5 options, so it will be a byte per entry.

The inbuilt RTC on a TinyScreen+ will be great for time stamping the response. 32Kb of SRAM at ~100 entries/bytes per day plus a starting time stamp of a few bytes, sholud give me plenty of memory and I guess the battery will run out long before I run out of memory.

I figure I will download the data once a week or so, and charge the device every second night or so, if it will last?

Is there anything I am missing...? Or anything I have wrong?
Any input would be greatly appreciated before I commit to a TinyScreen+ for this application.
