Pick a moment that matters: a trip, a birthday, an exam, a wedding, a milestone, or a fresh start. Keep it as a simple countdown, or give it goals and the steps that get you there. Kairos keeps your dates in view, and helps you arrive ready. • Goals, your way: - Set goals for any countdown, as many as you like - Add tasks. Schedule when to do them and save them for later when you're overwhelmed. - Build a routine. Check off recurring habits and keep the streak 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 what’s due across every countdown into one daily list, with suggestions for what to do next. • 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. • Count down, or count up. Track days until, days since, and yearly dates like birthdays that roll over on their own. • Always in sight. Lock Screen and Home Screen widgets keep your countdowns at a glance. The days are counting. Make them count. Arrive ready. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is in-app purchases: Lionote at none against Kairos's 3. Lionote also leads on device support (4 vs 1) and iOS requirement (13.0 vs 17.0). Kairos's advantage is update cadence (every 4 days vs every 2 weeks). On price and ads there is nothing between them.
