Sit Still is a focus timer that gives you somewhere to be. Most focus apps punish you, Sit Still keeps you company. A cat sleeps in a painted room while you work, and the reward for sitting still is a collection you build. Blocking is real, and as firm as you want it to be. The rooms are the heart of it: watercolour illustrations painted like the pages of a childhood picture book, meant to feel cozy and nostalgic — to stir a memory of being small and safe somewhere — each with its own soundscape. APP BLOCKING FEATURES Three app blocking modes for a focus session: Companionship, Whitelist and Strict. Additionally, app blocking rules allow you to put away the apps that keep distracting you throughout the day. You can lock the apps on a schedule of your own or hold them to a daily limit. You can also set a bedtime lock on a night schedule you choose. WALLPAPERS AND WIDGETS Any room you have can be saved to your Photos as a wallpaper, drawn at your phone's full resolution, with your cat in the corner or without it. There are widgets too: the room you are sitting in with your focus stats under it, the collection with a different room every hour, and your streak on the Lock Screen and in StandBy. A TIMER WITH THREE SHAPES Countdown, open-ended, or pomodoro. The pomodoro starts at the classic 25 / 5 / 15, and all three lengths are yours to change. A session carries on with the screen locked, and shows itself on the Lock Screen and in the Dynamic Island. A COLLECTION OF ROOMS A permanent collection of rooms, from a bookshop loft in Porto to a stilt house on the Mekong Delta, and two new rooms on the first of every month that leave with it. Every room has its own illustration and its own ambience loop, levelled against all the others so changing rooms is never a lurch. A CAT, AND THINGS FOR IT TO WEAR Six companions, hand-drawn and animated. Focusing earns whiskers, and whiskers buy cat accessories and the monthly rooms. Pet the cat and it notices. WHAT YOU NEED TO DO, AND WHAT YOU DID A task list that stays in sync with your phone's own Reminders. A record of every session — hours, streaks, and the note you left about what you were working on. Sit Still Premium is an auto-renewing subscription, offered monthly or yearly at the price shown in the app. Payment is charged to your Apple Account at confirmation of purchase.

Verdict
The clearest difference is review sentiment: Sit Still at 100% against Hustly's 47%. Sit Still also leads on monetization model (freemium vs subscription). Hustly's advantage is rating (4.7 vs 4.0) and ratings volume (48 vs 1). On price, update cadence, ads 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. Hustly sells 4 in-app purchases, starting at $3.99 per month and Sit Still sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
Hustly holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Hustly has 48 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 47% of Hustly's written reviews are positive against 100% of Sit Still's, so the app with the better star average is not the one people write more warmly about.
Hustly ships an update every 9 days, Sit Still every 5 days. The most recent releases landed on October 1, 2026 and September 30, 2026 respectively.
