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.

Verdict
The clearest difference is ads: Underlairs at none against Arctic Habit's shown. Underlairs also leads on ratings volume (8 vs 1) and iOS requirement (15.0 vs 17.0). 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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Underlairs sells 3 in-app purchases, starting at $0.99 per month and Arctic Habit sells 2 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 5.0 for Underlairs against 5.0 for Arctic Habit. That said, the two scores are not equally well evidenced: Underlairs has 8 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
Underlairs ships an update every 3 weeks, Arctic Habit every 2 days. The most recent releases landed on October 24, 2026 and October 23, 2026 respectively.
