I built a collaborative list app with priorities, sections and completion tracking
I got tired of messy task apps, so I built a flexible collaborative list system
I kept losing track of shared tasks, notes and files between WhatsApp groups, random notes and different tools.
Most task managers felt either too complex or too limited for simple collaboration.
So I built Colistu — a collaborative list app that’s simple, but still structured.
You can:
Create shared lists with others
Organize items using sections
Set priorities and track completion
Add notes, rich text and files
Use it for anything (tasks, shopping, projects, etc.)
The main idea is:
Not everything needs to be a “task manager”.
Sometimes you just need flexible, structured lists that people can actually use together.
I tried to keep it minimal but still powerful enough for real use cases.
Would really appreciate honest feedback:

Would you use something like this?
What feels missing?
Is this solving a real problem for you?
The “simple but structured” idea makes sense, but this is a tough space. There are a lot of tools that already cover parts of this... so it feels like the challenge isn’t building the features, it’s giving people a clear reason to switch from what they’re already using.
The use case is probably where this wins or loses. “Shared lists” is broad, but something more specific might land better. What kind of situation did you build this for originally?
Nice take with Colistu — I like how you’re positioning it as structured collaborative lists instead of another heavy task manager. The sections + priorities combo feels like a sweet spot between messy WhatsApp threads and overly complex tools, especially for lightweight team use or shared planning.
This could be a great way to validate it and get early traction too. There’s a competition where you can submit it — entry is $19 and the winner gets a Tokyo trip. Prize pool just opened at $0. Your odds are the best right now.

Looks interesting.
I noticed a small onboarding/UX point that might affect how new users get started.
Happy to share a quick audit if helpful.
This hits a real gap — especially the ‘WhatsApp + notes + random tools’ fragmentation problem. The idea of structured lists that don’t become full-blown task managers actually makes sense for lightweight collaboration.
What I’m curious about is positioning — because this space gets crowded fast. Are you seeing users adopt it more for ongoing shared coordination (like small teams), or more for temporary use cases (shopping, trips, short projects)? That difference usually decides retention.
I’ve also noticed some builders improve adoption by running small, high-intent experiments (fixed scope lists, capped participants, strong outcome focus) to see where collaboration actually sticks before expanding features — surprisingly useful for avoiding “nice but unused” products.
Feels like Colistu could sit in that lightweight coordination layer really well. Have you seen any specific use case dominate yet?
