- Export individual trips, or entire days, weeks, months, or years to standard GPX format files, for analysis and visualisation in hundreds of third party services and apps


- 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, weekly, monthly, and yearly activity summaries, showing duration, distance, calories burned, and much more, for every activity type
- Automated daily and monthly exports in GPX format or full detail JSON files
- Save walking, running, and cycling workouts to Apple Health
- Moves app data importer


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.

Privacy Oriented, Lightweight, Thoughtful

I’ve absolutely loved this app for the ~4 months than I’ve had it. It even saved me when my handheld camera had some issues and couldn’t save GPS data on the move. I was able to import my location from the gpx data at the time the pics were taken using another piece of software.

Lately, it’s been having an increasing number of data gaps though. I think the app relies quite a bit on motion to start recording, so if you’re sitting in one spot for a while before you start driving somewhere, it might not pick up on it. It’s also been warmer out lately though, so maybe iOS has just been shutting the app down more often to keep cool.

I hope that the developer is still actively working on this project. I love it, financially supported it for a month, and hope to support it more in the future when I have a larger income. There seems to be very little activity on the changemap site which worries me a bit, though. If I know the app is actively being improved, I will be much more likely to support it.

All that said, great app! I use it every day and I talk about it to everyone I know.

“Control your data”

The app touts “Control your data.” Except that’s a lie—the developer changed the app to lock any data older than 30 days behind a paywall, so really they’re the one that controls your data, not you. If you want the data back, you’ll have to pay. Not only that, but there’s no option to export all of your data out of the app, so you’re held hostage to a subscription just to be sold the lie your in “control of your data.”


The restriction hasn’t “existed for the past year” as the developer claims, I was able to view data more than a month old as recently as a few months ago. The restriction was added recently.

The developer also says there are “multiple export options” but they clearly indicate they are only for data moving forward, not your past data held hostage (on your own device) by the developer. Any past data you’ve accumulated is held hostage on your own device. The SQLite databases stored on your phone are inaccessible to the user. The “web exporter” mentioned by the developer is no where in the app.


I used the app as recently as August 1st and was able to view data more than a month old. I visited the Arc app website, there is zero mention of a web exporter.

I am not happy to have to repeatedly reply to antagonistic developer replies attempting to frame me as the liar in the conversation. Editing my review doesn't "antagonise and create animosity", it *warns* other potential users.

Developer Response ,

Final edit:

Unfortunately this user refuses to contact me directly by email, and is repeating false information here and is now insisting that I am a liar. I have been as clear as possible, and have been 100% truthful, but have no more time for this antagonism.

It is now necessary to ask this user to delete my app and move on. To this user, you are no longer welcome as a user of Arc. Your refusal contact me, your rejection of my factual and clear answers here, and your accusations that I am lying are beyond unacceptable. It is time for you to go. Goodbye.

My previous reply:


The app has not been changed. The restriction you see has existed for the past year. [Edit: This is quite true, regardless of what the user claims. The restriction has not changed in over a year].

To be absolutely clear: What has changed is your usage of the app, thus putting you into the "high frequency" user category. The restriction is not new, and has not changed.

The restriction is only for "high frequency" users - that being users who use the app at least 5 minutes a day on average. Casual users (ie users under that threshold) are able to use the entire app for free.

Your data is not held hostage. There is no lie. Your data is all available to you via the multiple export options in the app, via the web exporter [Edit: The web exporter is available via the Arc app website], and in the SQLite databases on your phone [Edit: The SQLite databases are entirely accessible to the user, via iTunes backups. Many users have already made use of this, to get direct access to their SQL data for data analysis purposes].

You have your data - I do not. It exists only on your phone and in your optional private iCloud backup. All of your data is available to you, regardless of whether you are a backer or not.

What is not available to you is the full use of the app's interface for browsing and analysing your data. High frequency users are required to pay their way, to support the project, in order to continue using the app's visualisations and analytics. Access to your data is not restricted.

If you are having difficulty exporting your data then please contact me directly from the Feedback & Support button in the app. [Edit: Again, *please contact me directly* if you are having trouble exporting your data. Rather than updating your review, just take the simply route of contacting me directly, so that I can assist you with your export, if you are unable to manage it with the information given to you thus far].

Editing your review will not change the situation. All it does is antagonise and create animosity.

If you genuinely want access to your data, I have given you all the options already. If you do not understand those options, or are struggling to make us of them, then contacting me directly is what you must do, so that I can assist you directly.

So please! Contact me directly. I am happy to assist with data exports. I am not happy to repeatedly reply to antagonistic reviews that cannot achieve any positive results.

Couldn’t be built by Apple any better

Here’s a privacy-focused location diary tool.. and there’s nothing else like it. All built by a single developer, all on-phone data processing and storage, daily automatic exports, tie-ins to photos and workouts and health.. I wish Moves App died years ago for things like this to come to fruition sooner.

In the future I’d love to see (in order of my own desires): Stationary activities like moves offered, Apple Watch abilities (so you one could leave their phone at home for a run and still see the track), and data editing/importing (as a means to do the same with any device or to split tracks back into separate categories).

I’m proud to be a backer and can’t wait to see what the future looks like for Matt’s projects.

Developer Response ,

Hi! Thanks for your kind words 😄🙏

I will be adding the ability to import workout routes as Arc timeline items soon. So that will make it possible for Apple Watch recorded workouts to appear directly in the Arc timeline. That one's going to be fun!

There's also more data import features on the todo list, and hopefully coming soon. Import from GPX, and other formats.

Thanks again 😄
