Ever find that "6 + 9" is easy, but "7 + 9" feels tricky?
Do you struggle with certain number combinations? I did! As the author of this app, I used to find combinations involving 8 or 9 particularly challenging. I also found it difficult to quickly calculate prices while shopping.
That's why I created this flash calculation app – to improve my own mental math skills! And while developing and testing it, I've already noticed a real improvement in my addition skills. I'm confident you'll see a boost in your own mental math abilities too!
I hope you have fun and enjoy your challenges!
HOW TO US
Numbers flash on the screen at a set interval. Add them up in your head!
STAGES
There are 20 stages, each combining one of 5 different digit lengths (1 to 5 digits) with one of 4 flash intervals (6, 3, 1, and 0.5 seconds).
The most challenging stage is 5 digits with a 0.5-second interval – a true test of your skills! If you ever reach that level, you'll be a real "expert"!
Each stage has a unique name.
- 1 digit, 6-second interval: "Shell" stage
- 1 digit, 3-second interval: "Prawn" stage
- 1 digit, 1-second interval: "Turtle" stage
and so on...
EXPERT MEDALS AND LEVELS
Earn an expert medal for each stage by answering correctly 5 times in a row at that stage. Your current level is determined by the highest-level stage where you've earned a medal.

- Register multiple challengers so that the whole family can enjoy the app on a single device!
