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 2.2.4


If you use Arc App regularly, and can afford to pay for it, tap "Become a backer" from the options menu, and support the project now.

Unlike most other free apps, Arc has a strict privacy policy, and does not collect or sell your personal data. There is no hidden or secret funding source that pays the bills. If you do not pay for it, I cover all of the costs myself. I cannot continue to do that.

Arc App has not reached its funding target, and is in danger of disappearing. If it does not reach that target soon, it will disappear. Until Arc reaches its funding target, I am paying all of the bills from my personal savings.

So if you don't want Arc to disappear, and can afford to pay for it, please do so now. Tap "Become a backer" the options menu, and support the project.

If you cannot afford to pay for Arc, that's fine! In that case, I am completely happy for you to continue to use the app for free. Those who can afford to pay should pay, as a matter of fairness. And those who cannot afford to pay should not be deprived of the same experiences or enjoyment.

# Arc App 2.2.4 Release Notes

### More details saved to Apple Health walking / running / cycling workouts

The “Save to workouts” button for these trips was not previously incrementing “Walking + Running Distance” or “Cycling Distance” in Apple Health. Now it does that correctly.

Make sure to grant Arc permission to write to those Health values when it asks!

### Bogus location data

I’ve added the much requested option for marking location data as “bogus”, for when your phone records location data that is so wildly wrong that no amount of mathematical magic can fix it.

To use this feature, either tap on the dot on the map for the nonsense data, or tap on its row in the “Recorded Activities” view. You will find the new “Bogus location data” option there.

This also means that stationary segment dots on the map are now tappable, for assigning to places, or changing activity type.

# Arc App 2.2.1 Release Notes

This update is mostly housekeeping. Lots of cleanup under the hood. The main change is a major under-the-hood upgrade to the Places database. Place names for visits should now appear immediately on app launch (except for the first launch after upgrade, during which there will be a brief database migration).

# Other stuff

- Shows day of week in the title of timeline views
- Finally a more sensible icon on the button to close the full map view
- Faster processing after making changes on the new confirm view
- Fixed the date format in JSON export files
- Removed a bunch of unnecessary fields from the JSON exports
- Misc bug fixes, crash fixes, battery use optimisations, processing improvements, and UI speed ups

Great app, amazing developer.


My original review lamented the lack of an importer for data from the now defunct Moves app. The developer wrote me personally to say that he had implemented an importer. I asked if it was robust and he responded to tell me exactly how it would work and what to do if it didn’t. The importer worked perfectly, bringing in about 5 years of data.

And the Arc app? It’s fantastic! After you’ve been tracking for a while you can dig into entries to analyze things like how often you visit a particular location, how long you stay, what times you’re usually there, and much more.

Thanks! I'm working on Moves data import right now, and will hopefully have it ready this week.

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!

Great moves alternative


I started using this app because a similar app call “Moves” went out of business. I was pretty upset because I have used moves for many years as my primary tracking app. However I found Arc which was aware of the moves going down and offered an import feature. After it’s all said and done Arc is an amazing app. Better than moves in nearly every way. I’m extremely happy with Arc and I’m excited to see how it evolves if it’s this good as a new app. Highly recommend !
