MindForge
Train your brain. No wifi needed.
Two games that sharpen reaction and focus, running entirely on your phone. No account, no ads, and no network code at all.
Built on what it refuses to do
Every constraint below is enforced in the codebase, not promised in a policy.
Two games, three speeds
Stroop Rush trains reaction under interference. Schulte Grid trains visual search. Each at Chill, Classic or Blitz.
No network code at all
Not "we don't sell your data" — there is nothing in the app that can reach the internet. No account, no ads, no analytics.
Four languages, two right-to-left
English, German, Persian and Kurdish Sorani, with real RTL geometry and Eastern Arabic numerals on the tiles.
Colour is never the only signal
Every answer key carries a fill pattern too — solid, stripe, dot, ring — so a game about naming colours needs no colour vision.
A streak worth keeping
A Daily Mix picks your session, a streak counts the days you showed up, and Stats holds every personal best and recent run.
Open source, all of it
Apache-2.0 on GitHub. The privacy claims above are checkable by reading the code, which is the only way a privacy claim is worth anything.
The whole app
Captured on an iPhone 14 simulator at 390x844. The last two are Persian, the same screens in right-to-left.
Not on the App Store yet
The code is public in the meantime — clone it, build it, or read it to check that the privacy claims on this page are true.
