# JuggernautAI vs Liftosaur

The clearest difference is monetization model: Liftosaur at free with in-app purchases against JuggernautAI's subscription. Liftosaur also leads on review sentiment (90% vs 73%). JuggernautAI's advantage is ratings volume (5.7K vs 390) and iOS requirement (15.6 vs 17.0). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. JuggernautAI sells 1 in-app purchase, starting at $34.99 per month and Liftosaur sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

That said, the two scores are not equally well evidenced: JuggernautAI has 5.7K ratings behind it against 390, so its average is the more settled of the two. Written reviews are what separate them: 73% of JuggernautAI's written reviews are positive against 90% of Liftosaur's.
