# Timo Partl Apps

> Timo Partl develops cross-platform apps for journaling, time tracking, photo geotagging, invoicing, and precise time display.

The app portfolio includes Diarium, WorkingHours, GeoPhoto, SubTotal, and AtomicClock. The apps are available across combinations of Windows, Android, iOS, and macOS, depending on the product. Several apps support optional user-owned cloud sync rather than requiring a proprietary app account.
