### 5/5 — Terrific

*2020-09-16, version 4.4.19*

Don’t normally review but I think this app is great and I am a free user that has not paid for premium

### 5/5 — Simple nice app

*2019-06-10, version 3.5*

Very nice app, but you have to pay for premium to be able to use all features.

### 1/5 — Joke

*2018-12-03, version 3.4*

Complete wast

### 1/5 — the preceding reviews are 100p accurate

*2018-12-02, version 3.4*

i gave the dev benefit of doubt.. and got snowed just like my predecessors. 

your app is completely 0x00.

enjoy another apropos reference.. 

floccinaucinihilipilification,
 [ floccipend ]- -- the estimation, or categorization, of something as worthless, floccipend is defined:: "to regard as insignificant".
(from Latin flocci pendere: "to hold at little value"). 

 enjoy the 4$ ... !'coder'

### 1/5 — Absolute Waste

*2018-10-28, version 3.3*

I don’t ever write reviews, but I’m taking the time to write one for this sad excuse for an app.  It’s utter garbage. You can’t do anything with the free version since it’s impossible to import another key without being a Premium member. So basically, you’re just wasting space on your phone. Don’t bother.

**Developer response:** Free users can have one keypair at a time and import up to 10 public keys.

### 1/5 — useless sandbox

*2017-05-09, version 2.0.1*

can't import or export keypairs, so you are stuck in a mediocre interface - USELESS

**Developer response:** Current version supports import/export of PGP keys to/from clipboard or text files. PGP keypairs of 1024-4096 bits can also be generated by CrypTon App
