Loci – Footprint Map & Heatmap
Auto-Track · Local · Encrypted
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Automatically record your routes and light up the places you've been on the map. Walking, running, cycling, and driving become color-coded trails that show transport mode and speed. No check-ins, no timers.
Not a workout app or a travel checklist — more like a map that grows with your everyday life, turning commutes, weekend walks, and the occasional trip away into routes and memories you can come back to later.
You probably don't realize how much ground you cover in a day. The alley you cut through this morning. The riverside ride last weekend. That spontaneous trip last summer — they slip away. A few months later you can barely place where you went, or when.
● FOOTPRINT MAP
Open Loci and your map starts to take shape: the streets you've walked, the neighborhoods you know, and the corners still waiting.
● AUTO TRIPS & LIVE TRAIL
Each time you head out, walking, cycling, and driving are organized into trips automatically — distance, speed, pace, elevation, weather, heart rate, cadence, stride, and active calories are all kept. As you move, the map draws your trail in real time, color-coded by speed or transport so pace and pauses show at a glance. The trail keeps recording even with the phone locked in your pocket.
● LOW-POWER
Using iPhone's motion sensing, Loci does not need to run high-frequency location updates all the time. When you stop, it lowers the recording frequency to save battery; when you move again, it captures your trail more often. In everyday use, a full day usually costs only a few percent of battery.
● TRIP DETAILS
When a trip ends, you get a detailed trip card with the full route replay, elevation and heart-rate curves, and selected photos from that day, chosen from your library for clearer, more memorable moments. After every drive, Loci saves your parked location so you do not have to circle the lot looking for your car.
● LIFE RECAPS
At the end of a month or a year, Loci turns that period into a short story: where you went, which new places you lit up, and what kind of weather followed your days. You can also search your records in plain English, such as "places I went from home last week" or "my longest drive this year." Loci finds the answer from your trail history.
● HEATMAP
Switch on the heatmap and the places you walk most often glow the brightest — your commute, your daily radius, the regulars, all at a glance.
● PRIVACY & SYNC
Your footprint stays on this device by default. If you want a backup, a new phone, or the same history on iPhone and iPad, you can sync with iCloud or WebDAV; data is encrypted on-device before syncing.
Start today. It may not feel like much at first, but when you open it again later, you may realize just how much ground your life has covered.
