What Makes Calculator Quest Stand Out

A calculator and an RPG combine to form a miraculous hybrid!
Includes bonus quick-typing game and math game!
※Rest assured, this app also works as a calculator.

  • Use for regular calculator operations! Calc mode!
  • Type the numbers and symbols as fast as you can! Quickdraw Colosseum!

This Utilities game offers engaging gameplay and regular updates for mobile players.

Community Insight:

Best calculator app on iTunes! So glad its back.


We do not mean to sound disrespectful, that is not our intent here, but this game has us passionate. We do not understand why you would release something as cool as this game and not provide a PAY FULL price to remove ads & play offline option? We could see if you were generating 100,000.00s thousands in income off the ads but we HIGHLY DOUBT it, going off reviews -> this game does not have a huge public awareness, to justify not offering a pay to remove ads option, business wise, this makes no sense. – Only reason for our two stars: + for excellent game – for atrocious ads Provide a pay to remove ads option, and Ill increase to 5 stars – SOMEBODY COPY THIS CONCEPT AND REAP THE REWARDS if somebody can copy this game not literally but same tempo and speed, retro graphics cool retro sfx. Ill throw $10 at you. This concept is that good. It seems, the dev of this game, does not need money, somebody else should just go ahead and take the money, very low hanging fruit.


If you got a system wide ad blocker which thankfully we do its great. But without one its terrible as Ads are now showing up on the top blocking off the numbers & the only way to remove is to use ether the older versions of weblock or have DNSCloak. Thanks for making a great app actually require a Adblock to use.


Ahh! We love this app. Its so much more fun and better than the default calculator. Sadly, it needs to be updated for iOS 11. If you are capable please update this app. We miss it.


This is a great app and one time when we killed all the monsters the app crashed immediately lol.


This is a fun app. The numbers on the screen being monsters, the mini games, and the 8-bit style just makes it fun. Pls advertise.


It's simple and cute, we like it. :) 5/5.


Awesome RPG calculator ever!!! 10000/10.


We can't help our self Is cute , pixel , fantasy , and fun . That all.


It's a better calculator then the boring calculator that the iPod has:).


When you get stressed and bored of your Maths exercise, this app will help you. You can increase your skill in equating and it's quite fun.


This is different but super cool.


We love the little creatures and the lol games :3.


It's a unique game!It's very interesting and easy to play.


Neat little calculator, a bit different.


Sure. Why not. We love both so it works.


It's just a regular calculator with nice theme visual.


The whole premise for this game is just stupid. It's also not in English and the graphics are horrible.


We think its bad, its just a calculator.


We have never seen a RPG Calculator before, and we don't think we will see one again.


Now able to calculate everything.


We like to play it when we have time and we like it very much.


What a great app and game, we love it so much.


This is a really funny quest. We recommend it.


It is very funny and useful, do not miss it.


It is really a great app, we love it very much.


The boring figures becomes lovely animated the idea is really good. The app is practical and interesting. However, we hope can enhance the calculation function. Can be recommended to the girls.


Very original concept but needs more "gameplay". We like it.


Both of the games gradually become harder. This game comes in handy to freshen up on your math. We liked the retro graphics very much.


Though the games lacks of the RPG depth aspects, playing it will actually exercise your intellectual skill all through out. It's more like challenging yourself on how far you'll go rather than doing quest.


A really strange combination of a simple calculator and RPG elements. Yet, it's pretty good for what it's worth.


A simple but good calculator with fun mini games.


Excellent use of calculator. We never thought using a calculator could be a goo game until now.


A very good game for our little child to learn the numbers, They can play the game and learn to caculate at the same time.


This is a superb concept, especially for school-going kids. Perform calculations, while at the same time, leveling up! Brilliant idea.


Great combo. The only downside here is the games are great for teaching you to type on the calculator quickly, but not necessarily your calculator you have at home.


Funny and we like its prety calculator perfect for child.


Would like it if there was more games to play with it.


A unique idea but doesn't flow well all the time.


It's kinda interesting. Not really something we would use as a calculator though.


Just a calculator with characters showing each number.


Could you make the quest a real quest? It's just a calculator, not a quest at all.


We like the old school music, reminds us of when we were a kid. We believe this game could go a lot father though. Could make it longer, give level ups, harder questions as you get further into the game, and maybe give them items like skipping skipping a problem they cant solve. Would love to play something like that, maybe we should make it thanks for giving us the idea lol.


It's a nice quick little game that is perfect as an iPod game for the fact that it's easy to pick up and doesn't take up too much time. Plus it functions as a simple calculator as well.
