# Second Nature vs Liva

The clearest difference is update cadence: Second Nature at every 2 days against Liva's fortnightly. Second Nature also leads on monetization model (free vs free with in-app purchases) and review sentiment (66% vs 57%). Liva's advantage is rating (4.7 vs 4.3). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Liva holds the better App Store score, 4.7 against 4.3. Both are backed by a comparable volume of ratings — 57 and 15 respectively. Written reviews complicate that: 66% of Second Nature's written reviews are positive against 57% of Liva's, so the app with the better star average is not the one people write more warmly about.

Second Nature ships an update every 2 days, Liva fortnightly. The most recent releases landed on September 24, 2026 and September 21, 2026 respectively.
