It's a life-changer for me. Now Byerrm is only ever one tap away. I also added the ability to adjust the volume of the app with the crown, and fixed a pesky crash that's plagued me for years! Hope you enjoy it. ### 5/5 — Have needed this! *2018-11-23* Plan to use instead of applause. Kids also love it. **Developer response:** I added stats into the app, mostly for my daughter who occasionally goes nuts on the app. She's frequently coming back to try to beat her high score "Byerrms Per Minute (BPM)", and it drives my wife crazy. ### 5/5 — It’s the byerrm life for me, now. *2018-11-08* #JustByerrm **Developer response:** Hahah.
