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.

What's New

Version 1.8.1

It's now much easier to mark a place as "Home". Yay!

- From the Edit menu on a visit, there's a new option "Mark this place as Home".

- If you haven't already made a private place for your home, you can set a custom title on the visit (eg "My House", "Home", etc), then choose the "Mark this place as Home" option, and a new private place will be created for you with that name. Hopefully much easier than the tedious old way of adding a Home place (which most people, including me, couldn't even find. oops).

- After you've marked the place as Home, Arc should from then on automatically recognise it each time you come home.

- Aside: This one had been on my todo list for over a year! For those who've been asking for it, sorry I took so long to get to it :)

Best Location Tracker!

Matt Loves Apps

This is the best location tracker app! I previously used Moves but it deleted my data and the app never gets updated anymore. Arc is highly detailed and very nice to use. The best part is that the data is stored in iCloud and private. Thank you!

Some features I would like to see in the app now that Move-O-Scope has shut down:
- Add an overview map of the world so you can see your all time travel lines to see where you've been around the world in one zoomable map.
- See the places you come from and leave to the most when viewing a specific location

Developer Response

Thanks for the kind words! We're currently working on a website which will hopefully have some visualisations similar to the one you mentioned :) And I'll add the "most common to/from places" to the todo list for the app. Cheers!

This is a very clean and simple app for those of us who want to keep a record of our location history but not have it in the hands of a large corporation or sold. Having said that, a statement regarding this could be more prominent in the app itself although you can find the clear statement in the privacy statement here in the iTunes Store. My favorite features are the export to gpx on a per day basis (nice if there was a way to do multi days at once), and the ability to update places and clean up the timeline as you go along.



Very cool app - it's like the google maps timeline feature, but all data is stored only on your phone (exportable, if you want).

There's a lot of calorie data and stuff in there, too, if you're into that.
