A few things
you might wonder.
Can I practice without an internet connection?
Yes. Core training, lessons, and progress work on your device. Downloading the app, making purchases, and restoring purchases need an internet connection.
Does it work on iPad?
Yes. Foldmetry supports iPhone and iPad running iOS or iPadOS 17.0 or later. The app includes English and Simplified Chinese.
What is the difference between Annual and Lifetime Pro?
Both unlock the same Pro features. Annual is a subscription, with a 7-day trial for eligible users. Lifetime is a one-time purchase. Apple handles payment and subscription management.
Is this an IQ test or an official exam?
Foldmetry is a spatial reasoning practice tool. Timed practice offers aptitude-style pacing, but it is not a standardized test and is not affiliated with an examination authority.
