That would be fine if it didn’t clear it every time I go back into pokemon go after manually entering it. Thankfully the renaming purchase works, as it should considering it’s being offered for free on other apps. Please patch asap. ### 3/5 — Doesn’t work most of the time. *2026-06-15, version 1.0.26* When I use it I often have to type in the moves myself because it never gets it. I do like how it tells you which pokemon are good against raid bosses tho that’s cool. ### 4/5 — Hmm *2026-03-26, version 1.0.25* For some reason, the app doesn’t work the same as it does on android. Maybe I’m using it wrong is there an overlay so one can play Pokémon GO and watch IVs simultaneously? ### 5/5 — Super slick and fast *2025-07-21, version 1.0.22* I paid for the upgrades. Very much worth it. Out of the apps that do renaming based on screen scrapping this is the most slick. I wish the history of seen Pokémon was slicker, more like what pokegene has. But the naming power here and how it scans is so much nicer. ### 5/5 — God dang this is good *2025-07-14, version 1.0.22* Now I know a trash if Pokémon’s ivs now I can see what to evolve ### 5/5 — Good and evolving *2025-07-09, version 1.0.22* Overall pretty happy with CalCy, the renaming could be more straight forward and have more diversified presets depending on user. Would like to see algorithm implemented ### 5/5 — very helpful to me and discovering levels of my pokemon. *2025-07-02, version 1.0.22* Very helpful ### 4/5 — Decent *2025-05-25, version 1.0.22* Could explain things a little better for some of us that aren’t that familiar with how it all works, but overall it’s a decent app ### 5/5 — Does what it says *2025-03-12, version 1.0.20* Little gimmicky at first, but once you get to learn how it works, maybe watch a YouTube video on it, it definitely helps. Especially with Pokebox and raids and all that shi. Would recommend. Only issue I have is that you need so many different apps to do so many different things. Poke Battler, Stadium Rank Checker, I mainly use Calcy IV to quickly check IVs and figure out level -> makes bulk importing to Pokebox a lot simpler with a spreadsheet. ### 3/5 — Bugged lately *2025-03-05, version 1.0.20* This is probably one of the best supplementary apps to Pokémon go out there but within the last few updates there’s been an issue where the app will scan the Pokémon currently with the IV screen open and the notification will pop up with the stat spread but it will fail to show up on the keyboard. At first I thought this was an issue with Kyurem since it has multiple forms but this issue has shown up on other ‘mons as well. Until this gets fixed, I’ll give it a 3. ### 5/5 — I love this *2025-02-19, version 1.0.20* The app works every time never had issues and you DONT NEED TO PAY I love this app and i never play without it ### 4/5 — Problema de lectura *2025-02-02, version 1.0.20* Excelente aplicación pero hace días después de la actualización en mi iPhone no quiere leer el IV del Pokémon. Por favor solucionen el problema, es la mejor aplicación. & Sugerencia seria posible que la versión de IPhone sea igual que la de Android está súper genial. Bendiciones! ### 5/5 — Great app *2025-01-27, version 1.0.20* This app helps so much for organizing and seeing how good my Pokémon are and my best Pokémon for gyms and what Pokémon in the gym I’m fighting that I should use great app I recommend using this app ## Most critical reviews (10 lowest-rated) ### 1/5 — Very bad I *2026-04-12, version 1.0.26* I waited over ten minutes to appear and nothing appeared so 1 star buns ### 1/5 — Inaccurate *2025-08-17, version 1.0.22* Things that say high percentages are actually one star or less ### 1/5 — Outdated *2025-08-12, version 1.0.22* Straight doesn’t work. Pokegenie is the only one that still works ### 1/5 — Yeah don’t bother *2025-07-08, version 1.0.22* Don’t bother downloading this app. It’s trash ### 1/5 — Don’t work *2025-04-11, version 1.0.21* Doesn’t work for my iPhone 15 pro max ### 1/5 — App doesn’t work *2025-03-27, version 1.0.20* this app doesn’t work at the moment. it’s supposed to work as a screen recorder while you play the game and give you notifications for the IVs of whatever you’re trying to catch in that moment. however it only seems to consistently work after you’ve caught the pokémon, which is useless since you have all of the information on its moves, IVS, and can just look up the pvp rank for the pokémon with that IV anyways. making this app completely useless. ### 1/5 — Doesn’t work *2025-03-16, version 1.0.20* Tried everything and the app will not show in game information as stated. A real bummer. ### 1/5 — Doesn’t work *2024-12-09, version 1.0.19* Doesn’t work at all. Downloaded this app a few times. Still doesn’t do anything is claims to do. ### 1/5 — Uncooperative *2024-06-28, version 1.0.14* Seeemed to be effecting my texting on private sites such as kredit karma and on my notes, a serious bug that I do not appreciate ### 1/5 — Doesn’t work *2024-03-19, version 1.0.12* Gave it a try to IV check Galarian birds before wasting Master Ball, set it up with my trainer level, etc. Hasn’t gotten one IV right yet on any mon I’ve caught. Not until the appraisal screen does it figure out the correct IV. ## Most praised reviews (10 highest-rated) ### 5/5 — Very good IV checker for iPhone *2026-09-05, version 1.0.29* I’m fairly impressed on how well this works, it’s fast response time, accurate results. I’m very pleased with this app, would recommend! ### 5/5 — Works well *2026-07-31, version 1.0.29* I did a quick trial and this worked better than PokeGenie on my device. Seems even better with fast scan (payment required, very fair price). ### 5/5 — reliable and refreshing:) *2026-07-09, version 1.0.27* no paying premiums for basic features (except for name3 which is weird since it's used in one of the default strings) , no taking screenshots which is AMAZINGG...all-around a great addition to my day-to-day PoGo experience ! thx <3 ### 5/5 — Awesome So Far *2026-07-04, version 1.0.26* No screenshots needed. Easy instructions to set up. You don’t have to pay for auto-deletion of screenshots or pay for premium once you run out of tries. Highly reccomend! ### 5/5 — Very Functional *2026-06-23, version 1.0.26* Allows for super specific customizations from PVP ivs to stats for raiders. Super easy to use and only $1.50 monthly for the premium version. ### 5/5 — Must Have *2026-01-05, version 1.0.24* Must have for every Pokemon Go player ### 5/5 — Finally! *2025-11-12, version 1.0.24* Finally! An app that reads the stats/IVs and is updated! Great job and thank you! ### 5/5 — Good *2025-10-16, version 1.0.24* Good ### 5/5 — Some missed scans *2025-09-29, version 1.0.22* Missing some of the regis ### 5/5 — Great app *2025-08-11, version 1.0.22* Love the app. It’s great for checking your Pokémon %s .
