Our Story
A brain-training app that lives on your wrist — no phone, no excuses.
Apple Watch is the most personal computer ever made — it's on your body every waking hour. Yet most watch apps are either fitness trackers or notification mirrors. We kept asking: what else can this tiny, always-there screen be good for?
The answer was sitting in decades of cognitive science. Memory training doesn't need a big screen. It doesn't need a keyboard. You only need a few seconds of focused attention — exactly what a watch session is.
We set a hard rule from day one: the app must work without the iPhone, fit within 60 seconds, and feel genuinely fun rather than clinical. Every design decision — the haptic feedback on a correct tap, the growing tension as sequences get longer, the immediate score — came from that constraint.
Mem Blitz is the result: three tight, replayable games that make the commute, the coffee queue, or the 30 seconds before a meeting actually useful for your brain.
Each game is grounded in established cognitive research — not invented difficulty
The Directions game targets visuospatial working memory — the brain system that holds and manipulates spatial information. Repeating directional sequences activates the phonological loop and visuospatial sketchpad described in Baddeley's model of working memory (1974).
The Color-Word game is based on the Stroop interference task (Stroop, 1935). When a color word is printed in a conflicting ink color, automatic word-reading competes with the deliberate task of identifying the ink. Practicing this builds cognitive inhibition — the ability to suppress an unwanted automatic response.
The Numbers game replicates the digit span task — one of the oldest and most replicated tests in cognitive psychology (Jacobs, 1887). Average adults recall 7 ± 2 digits. Research suggests that regular practice can gradually extend this capacity by improving chunking strategies and attentional focus.
Where Mem Blitz is headed
Directions, Color-Word, and Numbers — fully playable on Apple Watch Series 4 and later. Haptic feedback, sound effects, and personal high scores included.
Persistent high scores per game. Configurable haptic and sound feedback. Minimal, distraction-free watchOS UI.
Mem Blitz is currently in final review. We'll be live on the App Store very soon.
We're designing new memory challenges — pattern recognition, auditory memory, and more. Rooted in the same science, just as quick to play.
