### *---- "Face ID test not working"
Literally nothing is happening when I press begin test and then press the home button for a moment as it says. Idk man, this was recommended by a website for troubleshooting but it’s just not doing anything lol
-- MonicaQuinn, 2025-02-15

### *---- "Don’t bother"
Don’t bother 
Some tests do not work on iPhones 
Maybe Android, but not iPhones
-- iYanal, 2022-07-12

### **--- "Face ID does not work"
A few of the tests do not work.  Needed app to check Face ID but the test does not work
-- DH CA, 2022-05-19

### *---- "What a joke!"
Don’t bother, this is such an useless app. When I first saw it I thought ‘this will be good to find out about the iPhone I’m about to get’. Needless to say, it doesn’t provide any new information than you already know if you’re in the market for an used iPhone. My advice: do your research and you’ll get much more info than this app will ever provide.
-- iDevice.RAC, 2021-10-18

### ****- "Useful app, could be improved"
Good, comprehensive battery of manual tests. Too bad some other users don’t grok, dismiss the value. Free is excellent for pre-sale check on someone else’s device. Could be slicker in various ways: 1) automated serial # lookup from prefs, auto-submit to website, display results in app window. 2) Having to go to Photos app for video is goofy. 3) GPS zoom could be finer granularity. 4) could intercept button presses, automatically register. 5) Wish it supported earlier iOS versions. Regardless, worth at least $5. Sorry to see this seems to be abandonware; worth improving, perhaps selling to an iPhone repair outfit.
-- Doug Grinbergs, 2020-05-10

### ***** "Really useful"
I tried this app and it had all the possible testing features.  They have very accurate results.very happy with this app.Keep up the hard work! 😃
