osanka. — posture & mood

osanka. is a quiet companion for your posture — no streaks, no guilt, no noise.

Through the day, osanka. sends gentle, well-timed reminders to sit tall, roll your shoulders back, or take a breath. You choose how often and during which hours — the app stays out of your way otherwise.

How it works
— Set your reminder interval and active hours once, in a two-minute setup.
— A single calm signal appears when it's time to check in with your body — no counters, no red badges, no pressure to keep a streak alive.
— A live aura on your Lock Screen and widget quietly reflects your session, so you always know where you stand without opening the app.

Built for people who sit for a living
osanka. is designed for people who spend their day at a desk — founders, engineers, writers, anyone whose work keeps them still for hours at a time. It's built to fit into that life without becoming another thing demanding your attention.

Share your progress
Turn a session into a clean, minimal card — square, portrait, or story format — and share it wherever you like. No clutter, no watermark noise, just your progress in the app's own visual language.

Design
Graphite, warm accents, serif type. osanka. looks and feels like the rest of your considered life — not like a hospital app.
