Mobile App Concept · Context-Aware Reminders
ConceptThreshold
The reminder app that knows when you're actually leaving — not just where you are.
Fully researched and architected — problem, market, technical approach, and go-to-market plan complete. Not yet built. Available to acquire, license, or co-develop.
The problem
You add "buy milk" to a list while you're still at home. By the time you're downstairs and out the door, it's gone — not because you're forgetful, but because your brain quietly drops whatever isn't right in front of you the moment you cross a doorway. Every reminder app assumes you'll remember to check it; most people living in multi-floor homes don't, and existing location reminders only trigger on a flat map pin, not on the act of actually leaving.
The solution
Threshold is a reminder app that understands movement, not just location. Add what you need while you're still at home — no location tagging, no setup. Threshold notices when you're actually leaving: heading downstairs, out of the building, on your way — and delivers everything you need in one bundled reminder, right at the moment you can still act on it.
Key features
Zero-setup capture
Add a reminder while at home and it's automatically treated as a "remind me when I leave" item — no manual location tagging required.
Floor-aware detection
Understands when you're moving down through a multi-story building, not just when you cross a flat map boundary.
One bundled reminder
Everything you need surfaces in a single notification at the door — not five separate pings for five separate items.
Destination-aware reminders
Items tied to a market or pharmacy surface only once you're actually there, not the moment you leave home.
Learns your patterns
Personalizes exactly when a reminder fires based on which moment you actually tend to act on it.
Stays on your phone
No location history ever leaves the device — only the reminder text and trigger type sync across devices.
How it works
1. Add it, at home
Type what you need — milk, medicine, a courier pickup — no location tagging required.
2. Head out, like normal
Threshold quietly recognizes you're leaving, floor by floor, using motion and pressure sensors already in your phone.
3. One reminder, right on time
Everything you needed is bundled into a single notification exactly when you reach the door.
4. Destination reminders
Items tied to a specific errand surface once you're actually near that market or pharmacy.
5. Nothing tracked afterward
No location history is stored — only whether a reminder fired and whether you acted on it.
