Not sure if this would be of interest to anyone or even useful, but I sometimes needed this so I made it for myself. It uses the same algorithms as WFGUI so should be similarly accurate. It is very basic, as I have only just spent a couple of days putting the basic functionality together. Just needs mic permission and currently has no settings or options, just presents you with the frequency and W&F WRMS (DIN) and calibrated to only 3150 Hz. You can download the APK here: https://www.dropbox.com/scl/fi/v647...tter.apk?rlkey=smbljox9kuj82gxsf9u51blj3&dl=0 If there is some interest in such an app, I can look to putting it on the Play Store, and add more features such as peak, 3000 Hz baseline, etc.
So I am trying to get this up on the store now, but there is a new Google Play policy that requires a closed test phase with a minimum of 12 users for a minimum of 14 days. If anyone wants to help join this, you will need to PM me your Google Play email address so I can add you to the list of testers, then you can join using this link: https://play.google.com/apps/testing/com.sk.wowflutter If interested, drop me a PM and I'll add you. I have improved the UI and will look to add features such as switching between 3150 / 3000, and between modes such as WRMS and Peak.
