Before you install

If Android refuses to install the file, the system is blocking installs from unknown sources. Allow this app in Settings, then choose to install anyway when prompted.
If you see an "incompatible version" message, the build likely targets an older CPU architecture (ARMv7) that newer phones no longer accept. Look for an ARM64 (ARMv8) build of the same version instead.

Download FAQs

What can Mobile Observatory show for the August 12, 2026 eclipse?

It shows the eclipse path, local contact times, maximum obscuration, a rendered sky view, safety notes, and calendar actions for your location. The available information is location-based, so the displayed timing and visibility depend on where you use the app.

What does the Observing Plan Generator use to choose targets?

It uses your equipment, location, date, light pollution level, and minimum altitude. You can select naked-eye observing, binoculars, or a telescope when creating a target list.

What does the Version 4.7.5 modified build change?

The supplied label identifies Version 4.7.5 and mentions bug fixes and stability improvements. It does not specify a separate unlocked feature or explain a difference from the Google Play build, which is also listed as version 4.7.5.

What Android version does Mobile Observatory require?

Google Play lists Android 8.0 as the minimum requirement. The input does not provide a separate performance guarantee or device compatibility list.

Does Mobile Observatory require root access?

The supplied information does not state whether root access is required. It only identifies Android 8.0 as the minimum version and describes the app's astronomy and telescope functions.

The download link does not work

Reload this page and start the download again — links are generated per visit and expire. If it still fails, the file may be getting replaced with a newer build; try again shortly.

It says "App not installed"

That usually means a different signature of the same app is already on the device. Uninstall the existing copy first, then install this file. Back up in-app data beforehand, since uninstalling clears it.
