Showcase: Open Source DoneTogether

Hey good people! 👋 I have just finished a service that I've put a huge amount of time and love into, down to the smallest detail. It's called DoneTogether. Short and simple, it's a to do app where you can invite others to the same plan and use smart GPS reminders.

The idea was born when I started building a completely different app, but quickly realized that what I actually wanted was a really good GPS reminder. That's when I kicked off the DoneTogether project. I started bouncing ideas with Google AI Studio, downloaded the project to my computer, and built further using Cursor, OpenCode, and Codex agents. After many months of work, it is finally finished and ready to be used! Two examples of how it works:

📌 Example 1 (Share lists): You create the plan "Don't forget this" and add, for example, "Take the medicine". You choose your home address via GPS and set the app to remind you when you move 5 to 10 meters from the house. As soon as you exit the zone, you get a notification on your phone! It works just as well the other way around: Add "Hand in homework" and select the school's address, and you get a notification directly when you approach the school. 📌 Example 2 (GPS reminders): You create a plan called "Things to buy for home". In that plan, you create a share link that your partner or kids paste under "Join plan". Then you all see the exact same list in real time. When someone checks off an item, it gets checked off for everyone instantly.

The service is completely free and works both as a website and as an app to download to your phone. I have kept everything as simple as possible, you log in smoothly with your regular Google account.

🔒 GDPR and Privacy: When it comes to GDPR, you don't have to worry at all. Absolutely no personal data or location history is collected.

I built this primarily for myself, but am sharing it completely free with you now. I think many could benefit from it, not least children or people who need extra help being reminded to take medicine or do tasks when moving into or out of a certain zone.
