About KarLo
KarLo is a location-first productivity app. Instead of setting a time, you pin a task to a real place — and get reminded the moment you arrive there.

The problem
You set a reminder for 6pm to pick up medicine. But you're stuck in a meeting. By the time you're free, you've dismissed it and forgotten. The reminder was right — the timing was wrong.
Traditional to-do apps are built around clocks. KarLo is built around where you actually are.
The solution
With KarLo, you attach a task to a location — a pharmacy, a store, your office. When your device enters that geofence, the reminder fires. No more wrong-time alerts.
Our principles
Time-based reminders interrupt you at the wrong moment. KarLo waits until you're physically at the right place.
Every reminder you receive is one you can actually act on right now. No more dismissing alerts you'll forget.
Your location data is yours. We don't sell it, share it, or use it for anything beyond triggering your own reminders.
Errands, commutes, pickups, appointments — KarLo is designed around how people actually move through their day.

Creator
I built KarLo because I kept missing errands — not because I forgot them, but because the reminder always fired at the wrong moment. I wanted a tool that understood where I was, not just what time it was. KarLo is that tool.
