The single biggest predictor of a useful Mana app is the first prompt. Here's what we've learned from watching thousands of sessions.
Be specific about the moment of use
Generic: "Build me a habit tracker." Better: "Build me something I can tap once at 10pm to log whether I did my 20-minute walk, with a streak counter on the Lock Screen."
The second prompt anchors the app to a specific moment in your day. The result is something you'll actually open.
Name the constraints
Tell Mana what not to do. Mana takes constraints seriously:
- "No login. No accounts. No cloud sync."
- "Don't ask me to set goals. I just want to log."
- "No haptics. I'll be using this in bed."
Describe the home-screen surface
For most personal apps, the widget or Dynamic Island is where the value lives. Describe what should appear:
- "The Lock Screen widget should show today's count + a streak emoji."
- "Dynamic Island should show the active timer; expand to show controls."
Iterate in plain language
After Mana ships v1, talk to it like a person:
- "The colors feel cold, make it warmer."
- "The streak should reset on missed days, not pause."
- "Add a way to undo my last entry."
Each round takes about 30 seconds. Don't try to one-shot — sketch first, refine three times.
Avoid
- Naming frameworks ("use SwiftUI"). Mana picks the right tool.
- Specifying file structure. Trust the agent.
- Asking for "everything" — apps that try to do five things never get used.
