Glarm vs NerdTrack

If you often travel by train, bus, or any other means of transportation, you've surely found yourself in a situation where you're not sure if your stop is coming up soon — so you reach for your phone, open Google Maps, and nervously check when to get off. With Glarm, you don't have to worry about that anymore. Easily schedule an alarm that will ring as you approach your chosen location, and take a nap or keep watching the next episode of your favourite series in peace. Glarm lets you create an alarm that activates at a set distance from your destination. You can attach a note to the alarm, assign it to a category, and configure it to trigger every time you cross the boundary of a defined region.

NerdTrack records your location in a CSV file on your phone. No other data is collected and no data ever leaves your device. Full source is available at https://nerdtrack.org There is no interactive UI. Just grant location permissions, and it will log in the background. To stop logging, remove location permissions or uninstall app. The app uses the SignificantLocation and CLVisit APIs. The accuracy is low but it has very low battery usage. To get your log, open the Files app, and look for locations.csv in the Nerd Track folder. A config file will be created in the app's documents folder the first time it runs. Edit that file to change logging frequency or minimal distance. Force-stop and restart app to reload config. By default, the app records location: - Every 15 minutes, if you have moved more than 300 meters The CSV logs timestamps in the unix epoch format. Use 'dateconv -i %s' to convert it to something more human-readable. Some helper scripts are available at https://nerdtrack.org
