4/5Fun 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. 🖖😄

4/5Very amusing fake application
I’ve used this application to make a point on a few occasions, including to several years ago when I proved to my 8 year-old daughter that I could detect how many cookies she ate. Two problems exist with its use on OS15: (1) Emergency function no longer launches count animation and (2) there is no sound and nothing to adjust under Settings.

5/5AMAZING EVEN IN 2024
Downloaded this, knowing the risks based on the past reviews. However, I can’t say I’m disappointed. This was honestly an amazing app and it’s really fun too. The developer clearly listens to his users because even after a review said the sounds stopped working the sounds are now working again. Perfect for any Treckies 🖖

4/5Fun tricorder app
It has one bug that kept me from giving it 5 stars. The emergency data upload button no longer shows the upload video/animation. Otherwise everything else works.

5/5Still good today!!
I still use this app all these years later! It’s an amazing app and the only thing it needs is a phone case that looks like a “Quadcorder” back! All the sounds are perfect and the different functions use the actual sensors in the phone to give you somewhat relevant values. Worth every penny!

2.0
Yeah, yeah. I am sorry. This fell through the cracks. To make it up to you, I have added: - Support for devices up to iPhone 6+. - 7 New Sounds added - New Buttons for those with bigger screen. - New F1/F2 Mode - Background sound can be turned on/off in-app by tapping the speaker near the EMRG button. - More LEDs - New icon Things that went away. - Old scanning GUI (The one from the very first version) - Pressing the Library button, only plays a sound. You now cycle through the screens by tapping each GEO MET BIO button again. - Real world stuff. (GPS, Decibel, Magnetic Scanning). Those screens are still there they just display random numbers now. If you don't see something, it's probably because you have a phone with a smaller size. The new buttons / sounds / etc are for iPhone 5s and up. I wanted to fill up the space, so instead of making the buttons bigger, I added more.
