When searching for a pick, there were many with Micro USB ports, but only a few with USB-C so chose based on that. In the app, you choose what ear your working on, but found my brain needed the opposite view.
After initially pulling out chunks of wax, sometimes I feel blocked but can see it's my ear canal being irritated, and with it clear, can use olive oil drops or moisturiser on a cotton tip to treat the sore areas.
FYI there is also “Island” (white triangles on blue yellow background) on the Google Play Store which does similar if you don’t want to bother with FDroid.
I use it for isolating work apps, only oddity is having to install a second instance of my favourite keyboard and browser app, and if I want to attach a photo to say Teams, the file picker will show nothing until you switch it to browse personal files.
