We make apps
that make your life
quieter, sharper, better.
Viberostech is a small team building intentional mobile apps for iOS and Android. Calm, useful, well-crafted — no dark patterns, no noise.
Eight apps.
All made with care.
Letter Chain
A word game built on meaning.
Find words, set off falling-letter chains and see what every word means. A new Connections puzzle every day with 16 words in 4 hidden groups, a proverbs and idioms mode, and 250 hand-made chapters.
Dayama
Kanlı Okey, the 101 of Aegean coffeehouses.
Classic 101 Okey with the Dayama penalty: discard the tile that lets the next player open and it is written to your score ×10, ×20 or ×40. Smart bots offline, real players online, 16-player championships and private tables with friends.
Jop
Pis Yedili, played the coffeehouse way.
Get rid of your cards before anyone else. Sevens make the next player draw, the Jop goes on anything, and you say "Tekim" on your last card. Bots offline, online tables with friends and a championship every day.
Dreamscape
Sleep and relax soundscapes.
Layer up to five ambient sounds, tune each one and set a sleep timer that fades out gently. 21+ sounds, breathing exercises, guided meditations and sleep stories.
Three things we believe.
Calm by default
No streaks bullying you, no rage-bait notifications. Apps that respect your attention.
Small, opinionated
Each app does one thing, well. We say no a lot so you don't have to wade through settings.
Built to last
Indie pace, long horizon. We ship slowly so you don't have to live with our mistakes.
Building something we'd want to use every day.
Indie pace, long horizon. Each app stays small, opinionated, and quietly excellent. If that sounds like your kind of place, we'd love to hear from you.
