### 5/5 — This is actually real

*2019-07-13, version 1.0.33*

This app is really good at first when I was looking for an iv calculator for Pokémon go I was aspecting that it would be fake or wouldn’t work half the time but to my surprise it actually worked and the calculations are always spot on and come in very useful for when I’m deciding which Pokémon to evolve

Would recommend to others
Loved this app
10/10

### 1/5 — WAS the best app

*2019-01-30, version 1.0.30*

Was the best app for pokemon go at the beginning.. since a update , i cant log in. Always said “wait for the update” and nothing is being fix since several months, despite all the comments. Really disappointed, the peoples that manage this app doesn't care at all.

### 1/5 — Logout use the hard

*2019-01-23, version 1.0.30*

How come use the logout mode only...?

### 1/5 — Can you fix the problem?

*2018-12-30, version 1.0.30*

I’m still not able to login into the app :c

### 2/5 — Login mode

*2018-11-30, version 1.0.30*

Will you ever fix the login mode? Cause that was the best feature.

### 2/5 — Still waiting :|

*2018-11-16, version 1.0.29*

When is login mode coming? It needs to be done already

### 1/5 — “Login maintenance” is BS

*2018-10-18, version 1.0.26*

The thing that made this app so good and unique was the automatic rating system that pulled your trainer info from your account, but that feature has been dead for almost a year with no word from the devs.

If I wanted to manually input information I’d just use pokegenie.

### 1/5 — Indefinitely in “maintenance mode”

*2018-09-29, version 1.0.26*

The app is pretty useless if we can’t log into it because it’s 95% of the app. Please update it if possible or just pull it from the store if it’s not possible

OLD REVIEW: The app was great. It's helped me so much with which Pokémon I should cull. It would be nice is there was a way to get rid of the ads (in app purchase?). Additionally, there seems to be quite a long delay from tapping on the Pokémon from it actually showing it. If it showed the Att/Def/Sta levels in the list of Pokémon? Just a thought.

### 1/5 — What happened?!

*2018-09-04, version 1.0.26*

This app use to be amazing in that it was tied to the game and made it quick and easy to review the IV rating of all my Pokémon. Now for the last couple weeks it has had a login error under maintenance that makes the app useless.

Update: it has now been almost two months and this app still does not work. My friends and I are deleting this app and wishing it a peaceful death.

Update: so the app had an update, yet in the genius of the developer, they did not address the issue that the app does not allow you log in and use it. It is now 6 months of “under maintenance” and no help is in sight.

### 1/5 — Angers

*2018-07-28, version 1.0.26*

This app should be taken down if your not going to work on it anymore use to love it but the input takes too long since there’s not update! It’s worth one star now
