Focus and rescue your Arctic friends. Turn study, reading and deep work into a growing island of penguins, seals and orcas. MAKE FOCUS FEEL REWARDING • Set a session from 10 to 180 minutes. As you focus, the ice melts; completing the session frees your chosen animal or decoration. • Place your rewards on your own ice island. Watch penguins huddle, seals greet one another at the water's edge and orcas swim and dive. • Shape the snow and ocean with Focus Ice earned from completed sessions. Day and night follow your device's clock. UNDERSTAND YOUR HABITS • Tag sessions for study, reading, languages or exercise. • Follow your streak, compare day, week, month and year charts, and revisit your session history. • Turn on Deep Focus to lock other apps during a session. Screen Time permission is required; essential system apps remain available. • Choose focus sounds such as rain, waves, white noise, lo-fi and piano. GO FURTHER WITH ARCTIC PRO • Analyze time by tag, see your six-month focus grid and discover your golden hours. • Organize To-Dos under your tags and start a focus session for a task. Create unlimited tags. • Save Deep Focus presets of the apps you allow for study and work. • Enjoy an aurora over your island and double a completed session's Focus Ice without ads. • Unlock the orca after your first paid subscription purchase, rather than during the free trial.

Arctic Habit's advantage is update cadence (every 2 days vs every 3 weeks). On price, rating, review sentiment and in-app purchases there is nothing between them.
