User Reviews

Look4Sat offers an ad-free, visually appealing experience with useful features like custom TLE input and responsive developer support, but reviewers most often complain about instability, data loss after updates, usability quirks, device-specific issues, and occasional data accuracy problems. Improvements in reliability and cross-device behavior would help unlock its strong feature set.

Pros

Ad-free experience with no subscriptions.
Visually appealing interface and overall ease of use.
Supports custom TLE input for tracking satellites.
Developer is responsive and helpful.

Cons

App is glitchy and crashes frequently.
Updates erase saved satellites and settings or fail to display selected satellites.
UI/UX usability issues: difficult satellite selection, slow pass estimation, and conflicting time displays.
Device compatibility issues on some devices (e.g., Pixel 8 Pro; Samsung One UI) causing instability.
Data accuracy problems and incomplete satellite data (some satellites not found; keps data mix-ups).
