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.
