Hey everyone,

I released my first app to the AppStore yesterday. Its a free math game to improve your arithmetic and memory skills.

It would be great if you could check it out and leave some feedback

Thank you!

Is this a joke app?
13.50 + 3.00 + 13.00 = I enter 29.50 and get told wrong answer.
11.50 + 8.00 + 3.00 = 22.50 also wrong.
and many others. Bizarre.

Hey @Asp, thanks for your feedback!

This should not be possible, the way it is programmed. I also did a lot of testing and everything works fine.

I guess you did not recognize the multiplication. As you can see on the first screenshot, some numbers have a "2.0x" on the left side of the line. So you have to add the product to the current sum!
Maybe it showed you something like this:
+ 11.5
+ 8.0
+ 2.00 x 3.00

It would be great if you could check this again and let me know if it still does not work as expected

Thank you!

Hi Tobi_b. I picked up on the multiplication thanks. The screenshot shows -35 points for the correct answer of 35. Whats going on with that?

Hey Asp,

Thanks a lot for the screenshot.

Are the three visible numbers the first three numbers of this game? You have to sum up all the numbers which appeared - also those which appeared previously and you do not see anymore! Its part of the game to keep the total sum in mind while adding the new numbers. If you click on the "=" you always get the last correctly entered sum - add the new number to this sum.
It would be great if you could try this again

Thank you!

Thanks for the explanation Tobi. I had also tried to keep a running total of all the numbers on each successive screen, which didnt work either! I can see what is happening now though, with just a single number or product needing to be added each time. Makes perfect sense.

@Asp Im glad its not a bug

If you have the chance try it on an iPhone with a screensize of 4" or bigger. Its optimized for iPhones and it looks much better than on an iPad

Nonetheless this makes me think about implementing a better tutorial before the first game starts. On smaller devices the game logic and how the numbers appear on the list is not very clear because only 3 numbers are visible. On bigger screens you see up to 7 numbers and its more obvious that the task is to sum up all of them..

Thank you for the feedback, it helped me a lot!

Didnt realise the iPad display was that much different from a phone. Youre right though, seeing 7 numbers would clarify the logic, but a good idea to mention about the one number addition in the tutorial. Anyway, thanks for clarification as Ive been looking for a more complex math app. I only have the iPad so will stick with it. The display is fine now I know whats happening!

Hey Asp,

I changed the app from iPhone to Universal so there is an iPad version available now. The layout does not look very good yet but I think it looks much better than before. I will try to make further layout optimization on the iPad in the future.

Thanks for the update Tobi. Looks way better on iPad and I can now read the menus which were blank before. Good to have a challnging math app as most of these seem to be geared to kids arithmetic. Having said that I can only manage the easy time trial. Hope some more people join the competition.
