-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!
-
-Also, I'd like to mention Dr T.S. Kelso for his invaluable contribution to the industry and for his [Celestrak](https://celestrak.com) website, that stores, updates and provides access to TLE data.
-
-The app is built using Dagger2, Retrofit2, Kotlin and Kotlin coroutines, Architecture Components and Jetpack Navigation.

+### Let this app look for satellites for you!
+
+Thanks to the huge database provided by Celestrak and SatNOGS you have access to more than 3000
+active satellites orbiting Earth at this very moment. You can search the entire DB by satellite
+name or by NORAD catalog number. Track them with ease!
+
+Satellite positions and passes are calculated relative to your location. In order to get reliable
+predictions set the observation position using GPS or QTH Locator in the Settings menu.
+
+The application is built using predict4java library, Kotlin, Coroutines, Dagger2, Retrofit2, Moshi,
+Architecture Components and Jetpack Navigation. It is now and always will be completely ad-free
+and open-source.
 
 ## Main features:
 
-*  Calculating satellite passes for up to one week (168 hours)
-*  Calculating passes for the current or manually entered location
+*  Predicting satellite positions and passes for up to 4 days (96 hours)
 *  Showing the list of currently active and upcoming satellite passes
 *  Showing the active pass progress, polar trajectory and transceivers info
 *  Showing the satellite positional data, footprint and ground track on a map
-*  Offline first: passes predictions are made offline.
-Weekly updates of TLEs and transceivers DB are recommended.
+*  Custom TLE data import is available via files with TXT or TLE extensions
+*  Offline first: calculations are made offline. Weekly update of TLE data is recommended.
