Blue Logic Soft is a one-person software studio. Sudoku, backgammon, a task manager, a unit converter — few ads, easy on the eyes, offline when it can be.

The apps are on Android and iOS. The store listings and this site are the same studio.


We keep scope small. A feature has to earn its place. No account if we can help it; open it and it does the job.

Rain ambience, a nostalgia quiz and a digital shop live on other doors. The window here is the mobile apps.
