Nurrow

Nurrow is a focus timer with a pet that grows when you do. Pick a length, 25 minutes, an hour, whatever fits, and hit start. Your pet settles in beside you while you work. When the session ends, you've earned shards: the currency you spend on eggs that hatch into new pets to keep, name, and collect. It isn't a punishment system. Skip a few days and your pet gets a little glum, but it perks back up the next time you sit down. It's there to make starting feel less like work and more like showing up for something that's waiting on you. WHY IT WORKS Most focus apps stack timers on top of guilt. Nurrow flips it: the reward is small, frequent, and tied to something that feels alive. You're not chasing a streak for its own sake; you're trying to hatch the next egg and see what's inside. FEATURES • Focus and Chill modes, pick the pressure that fits your day • Customizable timer for Pomodoro, deep work, or study sprints • Hatch eggs and grow a collection of 100 pets, common ones hatch fast, rare ones take real focus time • Pet Home, a cozy room to visit and decorate while your pet roams on its own • Share your hatch reveals as a card with friends • Six cozy habitats to choose and unlock • Journal your sessions and track real focus hours • Ambient sounds: rain, café, nature, lo-fi • Local notifications only, no account, no login, no tracking OFFLINE BY DEFAULT No account. No email. Your data lives on your phone. Terms of Use: https://nurrow.app/terms Privacy Policy: https://nurrow.app/privacy
