Great App

I work as a paramedic. I love using this app in the field. Patients love it when I scan them and give them a quick diagnosis.

Great App to Cord Things

Nice to have when you need to investigate an alien planet or any radiation or EM anomalies. Well worth it. Get this!

Fun roleplaying app!

This app is a fun little roleplaying simulation app, turning your phone screen into a tricorder-adjacent screen, with authentic SFX, and cool little mock “data” that changes based on the 4 or 5 buttons you can press. Some buttons toggle, others bring up DNA scan info for the “BIO” button, etc.

None of the data correlates with anything your phone can “scan” or draw from like the Health app, but I didn’t really expect it to, it’s just a fun little app to keep on your phone for those sessions of playing the Star Trek TTRPG game, or visiting Star Trek Conventions.

I definitely think there’s room for improvement & expansion, as it only has the one screen which changes to show different types of data, (biological, geological, etc), but for $2, I would recommend it for any Trek fans.

Live Long, and Prosper, my friends. 🖖😄
