+## Acknowledgments
+
+I'd like to thank some people for their support and contributions
+during the development of RF Analyzer:
+
+- My partner **Anja**, who helped me a lot during the development of the new UI
+  (she's the reason this app finally has a clean UX and looks so polished!)
+- All **Testers on Reddit** who joined the beta test and reported issues
+- **Michael Ossmann** and the team around the HackRF which initially inspired
+  me to start this app years ago
+- **Martin Marinov**, the developer of the RTL-SDR Android driver
+- **Everyone who shared positive feedback** - your encouragement means a lot
+  and motivates me to keep improving the app!
