So it’s basically the same as protectedtext.com

Most phones allow you to make emergency calls from from the lockscreen. I wouldn’t bother with an app if my xiaomi phone allowed me to have text info on the lockscreen. Not just medical info but also "if found pls contact - "

I have this installed already. Might come in handy during the zombie apocalypse :)

I used to do this but I’d prefer to have medical aid details, blood type and contacts accessible from lock screen.

Betterbird is good, not really minimalist but worth a try…
