# Greenside AI vs SecondNine

The clearest difference is ratings volume: Greenside AI at 219 against SecondNine's 6. SecondNine's advantage is review sentiment (100% vs 92%). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Greenside AI sells 6 in-app purchases, starting at $14.99 per month and SecondNine sells 2 in-app purchases, starting at $4.99 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 — 4.9 for Greenside AI against 5.0 for SecondNine. That said, the two scores are not equally well evidenced: Greenside AI has 219 ratings behind it against 6, so its average is the more settled of the two. Written reviews are what separate them: 92% of Greenside AI's written reviews are positive against 100% of SecondNine's.

Greenside AI ships an update fortnightly, SecondNine every 10 days. The most recent releases landed on October 16, 2026 and September 30, 2026 respectively.
