Hi everyone,
I wanted to share a project I recently started working on called Tend (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 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.
Since this is in the initial development phase, I’m looking for feedback on the features and the UI.

How have you used AI in this project?
(we should standardise AI disclaimers in FOSS software like we do in science)
Why?
For boilerplate and some debugging. :)
Alpha Release is out
Link: Alpha v0.1.0-alpha.1
This is a very cool idea! I would love to see it, and I know many people that would be interested in using something like this.
Definitely going to keep an eye out! As far as frequency, it would be nice to add a “float” setting where a user could set a number of days as a window for reminders. So let’s say I want to be reminded every 14 days to check in with my dad. But I don’t want HIM knowing that I’m on a schedule, so if Iset a 3 day float, I could be reminded any time between 11-17 days.
Am I making any sense?
Thanks! I’ll consider your suggeestion.
I was about to ask this same thing. But I’d call floats fuzz or entropy or +/-
On the ozher hand, you could call it “Saturday is calling dad day“ :-)
Still a good idea for a feature.
Would love to use this app! When will you release the APK file?
Thanks! I’ll be releasing an APK within this day.
Absolutely love the concept. Will you eventually release builds on f-droid or some other source?
Thank you! I’ll be releasing it on F-droid, IzzyOnDroid, and Zapstore once I implemented the core features.
This, but only in the official fdroid repo
I second an F-Droid release because I don’t have a clue how to get it installed on my phone. I’m an über casual
Thirded!
As someone with ADHD, this is a pretty great concept.
Thanks! Happy to help.
I’m definitely not the target audience for this, but I know a lot of people who would love something like this. Please continue to post updates now and then!
Long term, it’d be cool to see iOS support as well, though that’s not easy to do. Since it’s still in early development, I’m curious if that’s on your radar. If not, makes sense of course. Just throwing that out there since you’re asking for feedback.
I will post an updates throughout the development.
iOS app is feasible but I’ve never really developed an iOS app. This could be the start I think.
Can you export/backup the data from the app?
Right now, it’s not included in the core features. But I think it’s an essential feature. I’ve already done such feature so it wouldn’t be hard.
Great idea! Do you also track important dates, like birthdays, anniversaries, etc.?

You will be notified if there are important dates set.
Excellent! I really need something like this, thank you for writing it!
Sorry, what does CRM stand for?
See also Sales Force.
It’s one of the most profitable industries that a surprising number of people don’t know about
Customer relationship management.
Where a company would manage and track their contacts and associated data.
Thanks!
never thought of something like this, sounds like a useful concept. thanks
Very cool! I definitely need something like this, personally. I forget to talk to people way too often.
Thanks! Happy to help
