The record

Purpose: The UNISTELLAR App turns a smartphone or tablet into a control center for exploring the sky with a UNISTELLAR telescope.
Catalog: Its Galactic Guide offers more than 5,000 celestial objects and suggests targets based on location and time of night.
Point and track: Users can select celestial objects for the telescope to point at and track, and can navigate manually with an on-screen joystick.
Images and sharing: The app lets users capture and fine-tune images, then share them with friends or the UNISTELLAR community.
Object information: The app provides descriptions and facts about celestial bodies, including their distance, magnitude, age, and type.
Citizen science: Users can collaborate with scientific experts, including NASA and SETI, on activities such as planetary defense and exoplanet research.
Platforms: The app is available for smartphones and tablets running iOS or Android, and cannot be installed on Windows, Linux, or macOS computers.
Device requirements: The stated minimums are Android 10 or iOS 18, 2 GB RAM, and 500 MB of available storage; FireOS, Kindle, Chromebook, Fairphone Open, and Huawei Harmony OS are unsupported.
Connection: The app connects to the telescope over Wi-Fi, and the telescope creates its own Wi-Fi network so telescope operation does not require an internet connection.
Updates: The October 1, 2026 app update added location and time handling changes, redesigned the observation bar, and fixed catalog search and visibility issues.
Privacy: The privacy policy says the app is linked to the telescope model and serial number and that UNISTELLAR collects product usage information such as activation date and place, responsiveness, and errors.
Support: UNISTELLAR provides an online help center with app guidance, including installation, minimum requirements, updates, and telescope control.
Maker and headquarters: The maker is UNISTELLAR SAS, headquartered at 5 allée Marcel Leclerc, 13008 Marseille, France.
Celestial catalog: The app’s Galactic Guide lists over 5,000 celestial objects and recommends targets based on location and time of night.
