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 ### 3/5 — IV go *2018-07-28, version 1.0.26* I like the app but it keeps saying that it’s under maintenance for this phone and it’s compatible I would like to log back in to see the ivs rating of my new Pokemon I caught ### 2/5 — 로그인 유지 서비스 업데이트 *2018-07-14, version 1.0.26* 로그인 유지 서비스 업데이트 해주세요. 로그인이 안됩니다. ### 1/5 — Error *2018-07-06, version 1.0.26* I got a response to a previous review saying there’s an update that fixed the issue. There’s no available update and the app still won’t open ### 2/5 — Was the Best poke go app for IVs out there *2018-07-02, version 1.0.26* Just need to know when the update will be here. Hopefully soon, getting tired of taking screenshots to see how good or bad my Pokémon are. 3 months of nothing is not garnering any good faith. ### 1/5 — Used to be 4 Star now 1 Star *2018-06-28, version 1.0.26* The app was near perfection when the auto login feature worked. For the last several weeks it displays a message about server maintenance. I used to suggest this app to friends over all the others that were manual or screenshot methods. I’ll update my rating when the app works again. ### 1/5 — Can’t login *2018-06-28, version 1.0.26* Can’t login. Keeps saying wait for update but there has been no update to fix login issues ### 1/5 — Red Warning! *2018-06-28, version 1.0.26* Title pretty much says it all, but just be aware that a ban will ensue if you aren’t quick with using this app as well as making sure to revoke permissions to use your email address. (I always just install the app, mark my Pokémon with the graded letter beside it’s name, log out, delete the app, and then disassociate the entire app with my email address. It’s the same as it never having been used at all as I still have yet to receive a warning or ban on my second account.) Here’s to hoping this helps someone/s! 😻Best wishes, loads of love, butt load of light, and happy hunting! ### 3/5 — Not updated? *2018-06-27, version 1.0.26* When will the developers update this app? This was by far the BEST app to get IV’s in a MASS SCALE!!!! Please update this app! ### 1/5 — Needs update *2018-06-22, version 1.0.26* It constantly says login services are under maintenance ### 2/5 — Android to iOS *2018-06-20, version 1.0.26* Giving 2 of 5 because on my android this was the BEST IV app out there but since switching to my iPhone the app doesn’t work tf you just stop working on it or something so I know to delete it or wait I have way to much to be inputting every Pokemon manually and it doesn’t even give a 100% reading in manual entry so please fix your app ### 1/5 — Dead app *2018-06-14, version 1.0.26* No longer updated, broke for 3 months ### 4/5 — A *2018-06-12, version 1.0.26* Are u going to update this app at all ### 1/5 — Bad *2018-06-03, version 1.0.26* Bad ### 3/5 — When is the fox coming? *2018-05-31, version 1.0.26* When is this app gonna get fixed? I loved it when it worked! ### 1/5 — Terrible. *2018-05-31, version 1.0.26* We’ve been waiting for a month for an update and they give no incite in to when or if it will be up again. Terrible. Update: they still have no date or definite answer if the app will ever be up and running. ## Most critical reviews (10 lowest-rated) ### 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 ### 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 ### 1/5 — Needs an update! *2018-07-20, version 1.0.26* Great app before just needs an update ### 1/5 — Broken app *2018-07-16, version 1.0.26* Can’t use the online version anymore ### 1/5 — Was good but not now *2018-07-14, version 1.0.26* Was a great app but no update in 4 months it doesn’t work anymore. Don’t waste your time till it gets updated. ## Most praised reviews (10 highest-rated) ### 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 ### 5/5 — Under maintenance complainers please read *2018-07-02, version 1.0.26* The reason it’s not working, and I agree it was a great app, is because of Niantic blocking third party scanners etc. Because of this the simple google login to review your Pokémon at a glance is gone. You will have to input manually as the app can no longer pull information from the POGO app via login. So really you stop complaining about it. It was a great app but Niantic ruined it. There’s no way for the developer to update it unless they switch it to screenshot method - which we all hate. ### 5/5 — Love it *2018-06-01, version 1.0.26* Hands down the best IV app out there. Can’t wait for it to come back!! ### 5/5 — Cool app but *2018-04-23, version 1.0.26* Did Niantic shut this app down too? ### 5/5 — Awesome app *2018-04-21, version 1.0.26* Makes it fun and easy to check your Pokémon ### 5/5 — Great ap *2018-04-20, version 1.0.26* Just need the update to come out already so I can use it again ### 5/5 — Update *2018-04-16, version 1.0.26* Needs new update ### 5/5 — Lost without it *2018-04-14, version 1.0.26* Seriously the best out there, when it’s working properly. You end up relying on it so much that once it’s down you’re lost and suffer using other checkers. Using on an iphone 6plus and never had any issues with soft bans or shadow banning. Really hoping they can fix whatever Niantic did and bring it back up soon. ### 5/5 — Love this App!!! Fast and effective! *2018-04-11* The only thing is that this update is taking forever to come out and there’s so many events going on right now that it’s crucially needed I refuse to buy more storage space. ### 5/5 — Please fix *2018-04-05, version 1.0.26* Please patch this app so it can work again --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
