Field notes
The app page says calculations cover dates 1900–2100, using published arithmetic for Tibetan dates and named astronomical methods for new moons and solar terms. It says results are checked against Edward Henning’s Tibetan calendars and Japan’s National Astronomical Observatory. Location can be requested from GPS, selected from an offline city list, or entered as coordinates; the page states that it remains on-device.
