Arc / Description

Automatically keep track of the places you visit, how you got there, and what you did while you were there. With a learning engine that gets smarter and more accurate the more you use it.


- Moves app data importer!
- Automatic recording of places you visit, with a learning engine that improves accuracy as it learns your habits
- Automatic recording of walking, running, cycling, driving, trains, trams, buses, airplanes, motorcycles, and boats, with increasing accuracy over time
- Collates place statistics, average visit durations, average calories burned, heart rate, and more
- Compare individual visit statistics to your averages
- Collates workout sessions and sleep times for each visit
- Altitude graphs for visualising mountain hikes, airplane flights, etc
- Daily activity summaries, showing duration, distance, and calories burned per activity type
- Search by name for past places and activities
- Automated daily exports in standard GPX format
- Export walking, running, and cycling to Apple Health workouts


Collection of Health data such as calories burned and heart rate requires an Apple Watch or other Apple Health connected device.


Arc is only awake and using GPS when you are active and moving. For the rest of the day Arc stays in a low power sleep mode, with GPS turned off, to conserve battery.

On a typical day of two to three hours of travel a single full battery charge should last from morning to evening without requiring extra recharging during the day. However longer trips (for example a long hike or cross country drive) may consume more than expected battery, due to Arc needing to be awake and recording, with GPS activated, for the duration of the trip.

For longer trips, I recommend plugging your phone into a car charger or battery pack, to avoid unpleasant battery surprises.


By becoming a monthly Backer, you help to support the project's continued development. Thanks!

Arc / Changelog / What's New in v2.2.8

  1. This one's another maintenance release, for fixing a bunch of minor bugs.
  2. NOTE: A handful of people have been experiencing extremely slow UI and processing in Arc since the 2.2.5 update. If you're experiencing this, I'm aware of the problem, and I'm on the case! I've doing everything I can to find the cause and get it fixed as soon as possible!
  3. I don't think this update will fix the slowness (or at least, it hasn't fixed it for any of the remote testing team who are experiencing the problem). But I've at least eliminated a bunch of "welp, I guess that's not it" possibilities, by fixing a bunch of minor bugs that I thought might be the cause. Hopefully I'll find the real cause tomorrow, and get another update out soon. (There's only so many corners it can be hiding in!)
  4. ## Misc fixes
  5. Fixed the editing of private place names
  6. Stopped duplicate places showing in place change lists
  7. Fixed the problem of backer purchases getting forgotten. (Tap the "Restore" button on the Backers view this time it'll work properly!)
