A new set at midnight. Rest days never break your streak.

Memtry is a free collection of short memory tests you can actually finish with your coffee. Each game targets one faculty: the span tests press working memory, the grids press spatial recall, Stroop presses attention. Your scores and streak stay in your browser; there is no account and nothing to install. Missing one day never breaks a streak here.
