### 1/5 — 広告邪魔

*2025-01-17, version 1.2.0*

画面にいちいち広告出すの邪魔してくんな！今すぐ消せ！

### 2/5 — let me buy it!!! (no ads)

*2023-03-27, version 1.2.0*

I do not mean to sound disrespectful, that is not my intent here, but this game has me passionate. 

I 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?

I could see if you were generating 100,000.00’s thousands in income off the ads… 

but I 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 my two stars:

+ ⭐️ ⭐️ for excellent game 

- ⭐️ ⭐️ ⭐️ for atrocious ads

Provide a pay to remove ads option, and I’ll 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.

I’ll 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.

### 1/5 — Great calculator app..

*2019-08-02*

If you got a system wide ad blocker which thankfully I do it’s great.
But without one it’s 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.

### 5/5 — Yes!  Thank him for updating!

### 5/5 — Needs update

*2017-12-07*

Ahh! I love this app. It’s 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. I miss it.

### 3/5 — Please update!

### 5/5 — Omg i dont know what to say

*2016-05-03*

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

### 5/5 — Seriously underrated app

*2016-05-01*

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. 😄
