About this app

*** Start enjoying the fastest and easiest IV calculator for Your Little Monsters ***

Calcy IV calculates the IV, DPS & PvP Ranks of your monsters and displays them conveniently in-game.

You can see possible IV even before catching a monster. Additionally, Calcy IV automatically generates nicknames in every possible format and assembles your perfect battle teams for Raids.

--------------

Calcy IV only relies on screenshots and needs no login. It can be used offline and is very battery-friendly. There is no need to leave the game while using Calcy IV.

--------------

** Overview & IV **

Every monster has hidden stats - the Individual Values (IV). They can be seen in the appraisal of your team leader and determine how strong a monster can get in terms of CP or when fighting other players.

Without needing any setup or any clicks, Calcy IV adds a little overlay while you play the game that perfectly integrates in it and helps you to decide which monster you want to invest stardust and candy in. With this app, you can see the IV range before you even caught the monster. Additionally, you can add several stats like DPS or PvP Ranks to the output that you otherwise would not see in the game.

When you see a good monster, you can tap the overlay to see its full stats, including DPS, the cost to level it up, and many more.

Are you a raider, a PvP player, a collector, or do you want to know just *everything* about a monster? Whatever your goals, you can set up Calcy IV completely to your needs.

** Trainer Battles / PvP **

Whether you are a PvP veteran or you want to start diving into the battles with other trainers, Calcy helps you finding the right monster for it.

In fights against other players all attacks deal different damage then usually. Calcy calculates the damage per turn accordingly in these fights.

Moreover, due to the CP limit for PvP leagues, the optimal IV for PvP fights are very specific combinations that may be hard to find. Calcy calculates these optimal IV and tells you for every monster how close it is to perfection (the so called "PvP Rank" or "PvP IV").

** Battle Simulation & Raid Counters **

Calcy's battle simulator will calculate the perfect battle team from all of your monsters for every raid. It is accessible by simply scanning a raid boss or pressing the overlay button a bit longer and then tapping the green raid boss symbol.

Calcy not only shows you how to beat the boss but also exactly how much damage you do. This allows you to decide whether you may need 2, 3 or 4 people for this raid. Of course, this calculation takes the different moves, weather and friendship buffs into account.

You can easily find the recommendations directly in the game with the help of a generated search string.

+++++ The battle simulator always works with high precision and includes the Breakpoints of your monsters (the next level where the damage of your attack-moves increases) +++++

** Renaming **

Calcy automatically generates a nickname based on many adjustable blocks (containing e.g. IV, move types, DPS, and PvP stats) and copies it to your clipboard. Then you can easily insert it in the game.

When it works, it is a great app. However, it is way more likely to only partly work on any given day. My app in particular likes to randomly decide it won't mark genders anymore. Like I can still see the gender characters on the Pokemon I renamed in Pokemon Go just a half hour ago, but now the app just doesn't see gender at all, so it's not a "phone having issues displaying characters" problem. Perhaps next week the app will deign to recognize and label genders. Inconsistent.

Hi, thank you for the report. Please try to reset the scan configuration of Calcy (in the 3-dot menu in the right top corner of Calcy) and try it again. If this doesn't help, please contact us under 'Contact Support' in the left navigation panel or at calcy-iv@tesmath.com and we can take a closer look.

This app is really helpful when assessing a Pokemon's fight power in battle. It's much easier to keep track of who I want to keep and who I want to transfer. Most of the time, it rates the Pokemon at a specific percentile. Other times it gives a range. 69-80%, even after an appraisal, isn't helpful. Otherwise, I love it!

Hi, thank you for the feedback. A range for % is displayed when there are multiple combinations of IV left. You can scan the appraisal of your team leader or level up your monsters to get a more accurate range. Right now, it is not possible to be more precise without breaking the ToS.

I almost never play Pokémon GO without Calcy IV. I mainly use this app to check and keep track of PvP IVs and ranks--which it is excellent for--and I recently started using it to generate my raid teams by highest DPS, as well. It's customizable to show only the stats that are relevant to your playstyle, and they continually come out with new features to improve it. It does take a little bit of setup to get the *most* out of it, but it's easy to set up. I use the bottom tier ad-free version.
