Recently, I fully switched to Arc and I’m currently running both Arc Timeline and Arc Editor simultaneously. Before diving into specific feedback, I want to start with something important:
I genuinely love the old and the new currently in development app.
The concept and the ambition behind Arc clearly show a huge amount of dedication. Building something this detailed and thoughtfully designed while also maintaining it is not easy, and it really shows. Compliments for that.
That said, while using Arc more intensively, I came across a few small things I wanted to share. Mostly observations and suggestions that might help improve an already great experience.
1. Initial Location Occasionally Defaults to New York
Sometimes when I open the app for the first time in a day, Arc immediately places me in New York, even though I live in the Netherlands.
It doesn’t happen every time, but often enough to notice. It might be some kind of fallback location or cached state, but I thought it was worth mentioning.
2. Places Tab Goes Back to 1987
In the Places tab (the middle tab), it’s possible to scroll all the way back to 1987.
I’m not sure if this is intentional, but I’m guessing there aren’t many users who were already generating usable location data back then 
Not a big issue at all. just something that stood out and might be worth validating or limiting based on actual data availability.
3. Import Accuracy: Spain vs. France
During my data import, I noticed something interesting:
-
Arc Editor correctly detected that I traveled to Spain last year
-
However, it didn’t register that I spent almost two weeks in France last year on the way to Spain
It might be related to how longer stays versus transit moments are interpreted, but I wanted to flag it just in case.
4. Feature Suggestion: Yearly Overview / “Life Cycle”-Style Insights
One feature I would personally love is a yearly overview, similar to a “life cycle” or year-in-review concept:
-
Comparing how often certain activities were done compared to the previous year
-
Seeing whether I walked more, traveled more, or drove more
-
Visual trends rather than just raw data
Along the same lines, it could be really interesting to integrate sleep data from Apple Health. That would make Arc feel even more like a complete daily life overview.
It would also allow insights like:
-
How often you slept at a specific place
-
How travel or routines impact sleep patterns
5. Map Overview per Activity (Full-Year View)
One of the most fascinating things I’ve seen in the old version of the apps and currently not in the new app is a map overview of a single activity across an entire year.
For example:
-
All car trips from the past year shown on one map
-
All walks or runs combined into a single visual
Seeing those patterns spatially is incredibly powerful and gives a unique perspective on how you actually move through the world.
Final Thoughts
None of the above are dealbreakers, quite the opposite. They come from genuinely enjoying the app and wanting to see how far it can go.
Thanks for building it and for clearly caring about every detail.
