OneADay Puzzlebook
An Android app with daily puzzles across Sudoku, tectonic, word guess, word seeker, binairo, 0h n0, and tent tree.
Small daily apps for real life
A family of focused apps for the rhythms that repeat: one puzzle, one list, one recipe, one calm little win at a time.
The apps
Each OneADay app keeps its surface simple and its purpose clear, so you can get in, do the thing, and get back to your day.
An Android app with daily puzzles across Sudoku, tectonic, word guess, word seeker, binairo, 0h n0, and tent tree.
Collect recipes, import from the web, cook step by step, plan meals, match dinner ideas, and build shopping lists.
Create lists or kanban boards for todos, plans, chores, projects, and the small things that otherwise evaporate.
The idea
OneADay is built around approachable, repeatable moments. The apps avoid noisy dashboards and oversized systems. They are meant to feel personal, clear, and useful from the first tap.
Focused by design. Every app has one main job and keeps that job close to the surface.
Made for everyday use. Quick enough for a spare minute, complete enough for real routines.
Part of one family. Shared warmth, shared polish, and a familiar OneADay rhythm.
