"Loops Habit Tracker" can do all of these things.
I love Loop Habit Tracker, I've been using it for almost 3 years and it works great.
Came to recommend Loop. also works for hydration reminders, housework reminders and general self improvement.
This isn't open source (but free if I recall correctly- I think I have a paid version but I installed it years ago): Recurlog will absolutely fit the bill for medications or other recurring tasks that repeat based on last-done date or due date (with or without automatic rollover = will reschedule for next day if one is missed).
You can set reminders at a specific time, and easily log directly from the reminder notification. You can log multiple times each day if you like, and add notes to the logged entry.
You can either set a "simple" recurring task without extra data, or optionally add data fields for text, numbers, Yes/No buttons or a time duration.
Manual backup to file. Unfortunately no encryption or visualizations.
I use it to log medications, reminders for physical exercises, cutting the dog's nails, when the dog is due to come in heat and how long it lasted, monthly hair dye and products and results etc.
I know it's old (last updated in 2018), but it's phenomenal. I've been thinking of making a similar app with more features as a hobby project, but I also have a 10 mo baby so 🤷🏻♀️
I use take-your-pill
Not released on any store and near as in I can tell has no telemetry.
Not sure about at rest encryption, but I just label my pill with the first letter or two.
Pretty old project, but it's pretty well done and doesn't need a whole lot of the "new" features.
I like that I can keep getting reminded as I don't always take it right when I need to.
Thank you for your suggestion!
Would you be able to provide some screenshots of the application? The website for the application doesn't seem to exist anymore, and the GitHub page doesn't have any images of the application. I must confess, however, that I'm somewhat hesitant to use an application that is no longer maintained, and isn't popular enough to provide a large enough chance of good security due to the sheer number of people looking at the source code and using the app. Granted, the latter could be solved by me "simply" looking through the source, but I confess that this doesn't feel entirely worth it, atm.
It's a pretty simple interface.
That's actually a pretty slick interface. It makes me wonder how many solid apps have been lost to obscurity.
That was part of why I stick with it. Does exactly what I need to to do and nothing more. It also works with my watch for reminders and confirmation of taking the pills.
Tasks.org on f-droid is great for this kind of use.
Interesting idea to use a tasks app for taking pills (presumably with it set as a recurring task). I agree that the format is quite similar in how the data is input and read, but I think there's still some merit to having a dedicated app for this purpose. Things like data visualizations for dosages, and tracking missed dosages and alternate reminders for things like stock I think are better suited to an app that is dedicated.
All about open source! Feel free to ask questions, and share news, and interesting stuff!
