This was exactly what I was looking for as it discreetly and privately logs my location without a lot of battery drain. I really like that I can leave notes at each location and it is easy to correct a particular location if need be. I rarely pay subscriptions for apps but for this one, I will gladly make an exception and pay the $4.99 monthly fee. Well worth it. Good job! 🙂
A great upgrade to a great app

This is the best app that I have ever used. The developer is responsive and dedicated. The update seems more accurate and stable than ever before. If you are concerned about the cost you should consider the fact that, if you are like me, you will use this app multiple times per day every day and it does exactly what it promises to do.
Private and flexible

I’ve been using ARC for more than ten years, since the old Moves app went belly-up. I like that my data stays in my control, I like the ease with which I can annotate my records, and I like that the app’s interpretation of my locations has improved beyond what GPS alone can provide as it learned to recognize my privately named locations.
What a disappointment
ACreek23
I’ve been a long time - paying - user for the original Arc app. While I agree with the developer’s assessment that maybe the time had come for a revamp, Arc Timeline 4 leaves a lot to be desired. For starters, the import of my old Arc data. Not only does it take to long - and I’m not getting a warning that my phone will be unavailable for 10-15 minutes -, it looks like raw unmanipulated data was imported from Arc. Meaning that if I corrected Arc’s mistakes - and there were plenty - those manual overwrites are lost in Arc Timeline 4. And that alone makes the app unusable for me for the moment.

• Visits without an assigned place now get their street address filled in automatically as you browse, including city and country, and become findable by city and country in search. (BIG-455)
• Set a visit's one-time title to its street address with a single tap. (BIG-227)
• Street-address titles display in a lighter style, so they read apart from places you've named yourself. (BIG-634)
• Run automatic exports on demand with new Run Now buttons in Settings, and the last-export times shown there are now accurate. (BIG-568)
• The AI assistant now handles date ranges like "last 30 days" and "since 2020" correctly, and answers questions spanning long histories more reliably. (BIG-582, BIG-564, BIG-548)
• Fixed layout and translation issues in GPX import. (BIG-630, BIG-637)
