Mobile apps succeed when they solve a problem that happens away from a desk — on the go, at home, or in a specific moment of the day. StartSeed generates ideas scoped to one use case, one platform and one revenue model.
A plant-watering reminder that uses your phone camera to identify species and adapts schedules to your local humidity. Freemium with a Pro plan at $2.99/month. It could be called Greenly.
A ferry-schedule notifier for commuters that pushes alerts 15 minutes before departure based on your saved routes. Free with ads, $1.99 to remove them. It could be called FerryPing.
A mobility-exercise timer for desk workers that suggests 3-minute routines between meetings using only bodyweight. One-time purchase at $4.99. It could be called Deskfit.
Before writing code, sketch the first three screens on paper. If you can't explain the core loop in three taps, the idea needs more focus.
A moment-specific need, a retention hook (notifications, streaks, saved data) and a monetisation path that doesn't require scale to be viable.
Pick the platform where your target users spend more money. For consumer apps in the US/EU, iOS usually converts better; for emerging markets, Android.
