🛠️ Building in public
🎯 2026: Ship 3 apps
$0 ⬜⬜⬜⬜⬜⬜⬜⬜⬜⬜ $1M

[Matteo Spada @matteo_spada]

This app is making 50k installs monthly and an MRR of $350k!

But How?

citing medical sources (Harvard) → gives authority and trust

visualized goal timeline → concrete and realistic outcome

paywall with bright colors "goals 4.2x faster" → higher subscription rate

I’m struggling with this right now 👇

My calendar needs to show:
• workout history
• nutrition macros
• water intake
But it’s getting crowded.
How would you keep this clean and simple?

[Jason Vuong @spacedevvn]

Idea: a platform only for people building something — and you must post progress every day.
No lurkers. No talking. Only shipping.

Would you use it?

If you look at this image, can you tell what my app is about?

Minimalist design is the teacher of masters.
