Perfect for watch – Brainess - Train your Brain Review

This is exactly what I wanted for my watch. Although the popular ones with subscriptions are all available for Apple watch, I refuse to keep paying for an app for as long as I want to use it (those apps just aren't worth the eventual hundreds of dollars). Brainess is a one-time pay app, and although simple, is the fastest responding app on my watch so far which makes it far superior to many of the puzzles and games I've already purchased (whose delayed response is frustrating and often game ending). This is the perfect little app for a quick moment of mental exercise. I highly recommend.
