 # Look4Sat: Radio satellite tracker
-Ham radio and weather satellite tracker and passes predictor inspired by [Gpredict](http://gpredict.oz9aec.net/) from [Alexandru Csete, OZ9AEC](https://github.com/csete).  
-Using the mavenized version of [predict4java](https://github.com/davidmoten/predict4java) lib under the hood created by [David A. B. Johnson, G4DPZ](https://github.com/g4dpz) and [Dave Moten](https://github.com/davidmoten).
+Amateur radio and weather satellite tracker and passes predictor for Android.
+
+The very app creation and design is hugely inspired by the open-source [Gpredict](http://gpredict.oz9aec.net/) desktop satellite tracking application, created by [Alexandru Csete, OZ9AEC](https://github.com/csete) and contributors, supported by the [Libre Space Foundation](https://libre.space/).
+
+The [Libre Space Foundation](https://libre.space/) team is also behind the epic [SatNOGS](https://satnogs.org/) project that provides an extremely easy to use [API](https://db.satnogs.org/api/) and [DB](https://db.satnogs.org/) with a huge amount of information about satellites, their telemetry and transmitters, which the app uses under the hood.
+
+For TLE data calculation and passes prediction Look4Sat uses the mavenized version of [predict4java](https://github.com/davidmoten/predict4java) library, created by [David A. B. Johnson, G4DPZ](https://github.com/g4dpz) and [Dave Moten](https://github.com/davidmoten). Thank you guys for your hard work making this lib efficient and easy to use!
