User reviews

Really good, but

This app is awesome. Genuinely one of the easiest to use UIs for a location app. My only issue is that sometimes it will stop recording your location in the background after 12-18 hours, without sending a notification or anything. Fixing this bug would be huge, or at least adding a notification system to detect it.

Best In Class

Bug: coloring by Time does not work when two or more databases are mounted if ANY database has no visible points in map. If ALL mounted databases have at least one visible point, then it works fine.
Typo: "databse" in Mounted Databases view

Finally, you get it. I've tried dozens of similar apps over the years, and dozens more this past week, and this is the one. Super clean fit of functionality to the data domain, solving the right problems the right way. I converted the past 10 years of my once-per-minute GPX data (hundreds of MBs) to your sqlite format and mounted it and it works great (except for the one bug above). I have a number of feature requests and suggestions which I'm sending by email, but really if you resolve just the bug and the other ones marked with "!!!", I would consider the app perfect. I'll drop those top feature requests here though:

- "Next" button that takes the current datetime interval and shifts it forward so the new Start is the old End. "Previous" button that does the opposite.
- Option to pick a personal-midnight day separator. I get home after midnight fairly often, but I get home after, say, 5am ~never. Splitting by actual-midnight scrambles a lot of my days.
- "All" to actually show all the data available in the databases and not just the artificial 2023-2033 range.

Finally - Privacy First Location Logging!

Awesome way to track travels, commute, and races. A private alternative to Strava!

Super nifty and useful!

Great privacy focused way to track my location for data visualization projects, while not giving my data to Google
