Customer Reviews

Great to find a Trachtenberg coaching app!

The technique is quite challenging so finding this is a great help.

Once you get used to the unique interface it's great. I'm finding the time constraints in the tests quite challenging but I suppose that's the point, only when you get proficient at a particular test are you ready to progress to the next stage.

My only minor quibble is that the app works perfectly on an iPad except that it's permanently in portrait mode (which is fine) but doesn't rotate by 180 if you turn the device upside down. Unfortunately this means that the app is always upside down if you use the standard apple folding case.

Superb app

I learnt this system from the book and use the app on my daily commute. It really is superb for sharpening and perfecting the techniques needed.

I cannot fault it but would like to make a few suggestions.

Firstly, it would be nice to have an overall test to practice several techniques, instead of constantly switching. The user could select the multipliers and the amount of questions for each.

Secondly, a summary screen would be handy, listing all methods; x11 - C+N, x12 - 2C+N, etc.

Thirdly, how about either another app or update to the multiplier or divider app which covers square & square roots?

Fourthly, another app which teaches/generates fast addition sums, with an answer checking facility.

Finally, a speed adder to add 2 & 3 single numbers together against the clock, up to 29. This would help speed up all calculations. Also, a combined super app, free or reduced for owners of both current apps?

Thanks devs. Very good work.

Ps: why are the ratings not shown for your apps? There are now 3 reviews for this one.

Great. Trachtenburg practice!

Been trying to learn thus from the book. But this is much better as there are timed trials and as many practice questions as you want. Great for hardwiring the techniques!
