### 5/5 — Amazing!

*2026-07-05*

I didn’t think I had so many dead pixels on my phone! Should’ve known from the amount of cracks I have on my screen. This app works so well to test out my phone for any damages. Definitely using Synapse in case I buy a new phone.

### 5/5 — Simple but Effective!

*2026-07-04*

The details this app gets into is game changing, I didn’t even know you could test these!

### 5/5 — Ghost touch?

*2026-07-04*

For someone who replaces screens and cameras all the time and need a form of quality check, this is definitely the way to go for a fast and easy touch test

### 5/5 — Saved me time and money !!!

*2026-07-04*

Excellent app! It has helped me a lot with my business by checking phones before I buy them. The basic check is free and works great. In my case, I decided to pay for the premium version to get more detailed information about any possible damage to the phones, and it has been totally worth it.

It has made my job much easier. It's fast, reliable, effective, and offers great value for the price. I highly recommend it!

### 5/5 — Great for checking phones

*2026-07-04*

I really like that you are able to check the phone before buying it specially when I buy on OfferUp or FB you never know if you’re getting what you paid for definitely worth downloading this app. Specially if you are buying an iPhone, and want to make sure the camera works, screen, that it charges. I’m very happy with it.
