Pain diary app

I would create a Google Form questionnaire for her to use.

Very easy to do and can be customised to whatever questions or data that you want it to input. Yes/no, multiple choice, radio buttons, free text, scores/10 etc. 

Any responses will output to a timestamped Google Sheets spreadsheet, making analysis, tracking and visualisation of any trends really easy.

Then set up a recurring reminder alert using Google Calendar. Include the hyperlink to the questionnaire in the reminder.

I did something similar to Peekay on excel using traffic lights to grade pain am and pm and frequency, had looked at apps like this one but never got round to using.

Like, three or four calendar entries a day? Or is there a better option?

Yes,

If a pain entry needs to be done at say 0800, 1200 and 1600, then set up three meetings, one for each of these times then set the 'repeat' to be 'every day'. You will then get the notification every day at these times.

Google Forms is a really great tool. It is worth investing the time in making the form/questionnaire easy to fill in to reduce the faff later on.

Edit. If they already use their Calender for normal life admin, then might be better to quickly set up another account so as not to clog it up with diary reminders.

I’ve used Daylio as a general purpose journal in the past. It can do the regular daily reminder and you can customise the question it asks you as well as respond by tapping a few buttons. It also gives reports so you can see trends.

I bet you can set it up to do what you need with minimal fuss.

I would rather the app did the reminders rather than spam the calendar with reminders.
