Hi everyone,
I wanted to share a project I recently started working on called Tend (an Android app built to help you automate the scheduling of your social life).
The idea originally came from a discussion on r/fossdroid about how hard it is to keep in touch with friends and extended family without relying on algorithm-driven social media or bloated, cloud-based business CRMs.
Most “Personal CRM” apps require you to upload your contacts to a random server. I wanted something that was 100% offline, private, and simple.
What it does: You can think of it as setting up cron jobs for your relationships.
-
Contact Cards: Create dedicated profiles for people you want to keep up with (Name, notes, phone, socials, etc.).
-
Custom Frequency: Set a “check-in” schedule (e.g., every 14 days, monthly, quarterly).
-
Smart Reminders: The app will notify you when it’s time to reach out.
-
100% Offline: Everything is stored locally on your device via SQLite/Room. No accounts, no telemetry, no cloud sync.
I’d love your feedback! Since this is in the initial development phase, I’m looking for feedback on the features and the UI.

Looks really interesting. Definitely post an update when it’s on f-droid.
It’s a very big feature to implement but if you happen to have enough time and energy, making a self-hostable server part that would sync contact lists between devices would be pretty useful.
Actually an even simpler approach would be to add an option to have the DB file in a regular directory on internal or external storage (not in the special Android app data folder) and then Syncthing would do the rest.
Orrrr, maybe just let it sync with an ldap server.
Import and Export features are already planned. You would choose your preferred backup/export directory because I know that android data directory cannot be accessed by many especially on newer android versions.
I usually add some Nextcloud integration instead of custom server. Implementing WebDAV is easy. I let the user choose in they want to export/import from/to cloud or local file.
Haven’t used WebDAV services. I’ll focus on local import/export for now since it’s on early development stage. I’ll be listing features suggested though for tracking.
I don’t really think it’s needed here. I’m just saying WebDAV is easier than writing dedicated server for self-hosting in case you decide to add some external import/export.
Really cool project. Will be keeping an eye on it!
Thanks!!
Doesn’t having an app for reminding about certain dates defeat the purpose of celebrating them? Isn’t the whole thing in showing that they are so important to you that you remember them? Why would they want to complicate your routine?
I am terrible at this. I have had to build the functionality of this app through other means. If this was available, I would have used it instead. I am going to use it now.
Sometimes you have to accept you need help, in my experience. Better this than losing people.
But what if you forget? Why risk it when you don’t have to? There is no shame in not remembering and needing to write it down. If you always remember than that’s good for you but a lot of people don’t.
I understand this as an immediate reaction to software like this, but I have to disagree. I care about so many people… too many people. I want to keep up with them because our relationships are important to me. However, the human mind forgets stuff, even things that are important. Sure, I’ll remember someone’s birthday most of the time, but this is insurance that I won’t, it’s insurance that I won’t lose meaningful connections because I got too busy with work or passion projects.
Well not everyone remembers everything, even the most important things. Just like me, who always forgot where I put my smartphone after a couple of seconds, or even my partner’s birthday. I’m the worst at remembering.
Think of it this way: I feel theyre important enough for me to bother setting up a complicated system for them
if you see it from the other people prespective, they dont really know if you actually remember or you get reminded by some sort of system.
Alpha Release is out
Link: Alpha v0.1.0-alpha.1
first off: super useful project.
the two biggest things I can think of are contact list imports and exports. I could see myself adding my immediate family manually. more than that and it becomes a chore rather than a setup.
Thanks!
It’s not currently listed as one of the core features but we’ll get there soon.
Finally someone who read my mind AND had time to implement it 😆 i had a similar idea (although probably with a little different scope) a while ago and thought ‘finally a useful project to learn this mobile development thingamabob’ but never came around to it. Hopefully ill come around to test your app! (No promise unfortunately, the broodling turns 4 weeks next Wednesday, so I got other priorities atm)
I’ll be releasing an alpha version this day. You can watch the repo if you want. :)
That’s a neat idea!
Thanks!!
I was just thinking about creating a spreadsheet with people’s contact info, notes, and a picture. I guess an app would be preferable, especially if there were a web/desktop version, and it was compatible with a spreadsheet (can export from/to a spreadsheet).
