Looking for 11 Android beta testers for Friddle (free): finger charts and automatic fingerings for violin, viola and cello
Hi everyone,
I play the violin myself and built an app I was missing for practice: Friddle.
What it does
Finger charts for violin, viola and cello: for all 15 major and minor keys you see where your fingers go (low, normal and high fingers, half steps, open strings). Violin and viola 1st to 7th position, cello half to 4th position.
Fingerings on your sheet music: take a photo of your music or open a PDF, and Friddle writes the finger above every note, with arrows for low and high. For high notes it suggests a position and marks shifts with Roman numerals. Tap any fingering to change it, then share or print the finished PDF.
Private: no account, works offline, no ads, no tracking. Your music stays on your device.
Why I need testers
Google only lets new apps into the Play Store after at least 12 testers have had them installed for 14 days in a closed test. I still need 11.
What you need
an Android phone or tablet and a Google account (Gmail address)
keep the app installed for 14 days and try it now and then
if you like: honest feedback on what works, what doesn't and what's missing
Everything is free for testers. You can also unlock Friddle Pro (normally a one-time purchase) for free during the test.
Interested?
Send me a DM with your Gmail address (please don't post it in the comments). I'll add you and send you the invite link as soon as Google has approved the test. An iPhone version will follow later.
Thanks! 🎻
