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.


A free trial, active subscription, or Lifetime purchase is required to use the app.

What I’ve been looking for!

I’ve been looking for a Moves replacement for a long time that isn’t Google Timeline for obvious privacy reasons and Arc is easily the replacement.

It works really well (there are some data gaps here and there but nothing major), the interface is great, I can edit all the data it captures, I haven’t noticed any battery impact, and best of all it’s all on my device and my data goes nowhere near Google!

Hoping to get an Apple Watch app and some new features! 🤞

Thanks to the dev team, you’ve done a fantastic job and I’m very happy to be a project backer!

Pretty good.

Starts off a little inaccurate, but after you spend a few days correcting it it works pretty flawlessly. It kept detecting my car as a bicycle going at 60kmp/h. I spent a good 15 minutes for about 3 days correcting it all to car. App now works great and gets it right quite frequently.

Best location tracker

I’ve used this app with gyroscope and this is more accurate than gyroscope places. Well worth the subscription. My question is lifetime is that lifetime of the app itself or is it lifetime no matter what even if the app is upgraded ie Arc 2 etc…

Developer Response ,

Hi! Thanks for your review!

The Lifetime Backer option is forever, for all versions of the app now and future, including companion apps (of which there are two in the works, and one arriving very soon).

Thanks again!
