Niche, but if anyone has a #Kardia #KardiaMobile portable ECG and has a rooted Android phone, be aware that they silently changed the app to not run on rooted phones with the latest update. I did not appreciate finding this out on a bike ride when I wanted to take an ECG. (Hiding it in Magisk works, but I had to clear my data to stop it from crashing, so I've also lost my historical ECGs. Luckily it's only been half a year or so.)
