Pick a moment that matters: a trip, a birthday, an exam, a wedding, a milestone, or a fresh start. Attach the daily commitments that get you there. Then count down, and show up. Kairos turns your countdown into a plan, and helps you arrive ready. • Commit your way, for any kind of goal: - Build a streak. Check off recurring habits and keep the chain going. - Hit a target. Track progress toward a number: miles run, pages written, money saved. - Hold the line. Count the days you've stayed away from something, or count up from day one. • Everything in one place. Your Today view gathers every commitment from every countdown into a single daily list, so you always know what today asks of you. • Stay on pace. Kairos shows your history and projects what it takes to finish on time, so you never have to wonder if you'll make it. • Always in sight. Lock Screen and Home Screen widgets keep your countdown and your commitments one glance away, and you can check them off right from the widget. The days are counting. Make them count. Arrive ready.

Verdict
The clearest difference is in-app purchases: KeyZ at none against Kairos's 3. KeyZ also leads on ratings volume (10 vs 2) and iOS requirement (12.0 vs 17.0). Kairos's advantage is ads (none vs shown) and update cadence (every 3 days vs monthly). On price, rating, review sentiment and device support there is nothing between them.

Both are free to download. Kairos sells 3 in-app purchases, starting at $4.99 per month. KeyZ asks for nothing beyond the download.
On the App Store both sit at effectively the same score — 5.0 for KeyZ against 5.0 for Kairos. That said, the two scores are not equally well evidenced: KeyZ has 10 ratings behind it against 2, so its average is the more settled of the two. Written reviews are what separate them: 93% of KeyZ's written reviews are positive against 100% of Kairos's.
KeyZ ships an update monthly, Kairos every 3 days. The most recent releases landed on October 24, 2026 and October 13, 2026 respectively.
