EDR-Logger (GPS): Automatically records when and where you are throughout the day

An iPhone app that automatically records where you were and when throughout the day.
Recording continues even when you don't open the app. The paths you walked, the roads you drove, the places where you stayed still—all are recorded.

■ What you can do
・View a list with timestamps of where you were (stays) and when you were moving (movements)
・See the route (trajectory) of the day on a map
・For times that couldn't be measured, such as inside subways, it records them as "unknown"

■ About battery
While stationary, GPS is put to sleep. It turns back on when you start walking, driving, or when it detects you've left a location.
Battery consumption varies depending on your device model and usage patterns.

■ Records stay only on your iPhone
Records are not sent anywhere. No account registration required.

■ Pricing
Recording and viewing within the app are free with no time limits or caps.
The only paid feature is the ability to export records outside the app (one-time purchase of 780 yen): automatic backup to your Google Drive, iCloud Drive, Dropbox, etc., and export to CSV, GPX, and other formats.

When used together with "GP Esper" (iPhone) by the same developer, GP Esper doesn't measure on its own but instead uses the locations measured by EDR-Logger.
