# JuggernautBJJ vs Roll Time

The clearest difference is monetization model: Roll Time at free against JuggernautBJJ's subscription. JuggernautBJJ's advantage is ratings volume (499 vs 28) and iOS requirement (15.0 vs 18.0). On price, rating, review sentiment and update cadence there is nothing between them.

Both are free to download. JuggernautBJJ sells 1 in-app purchase, starting at $19.99 per month and Roll Time sells 1 one-off in-app purchase. 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 JuggernautBJJ against 5.0 for Roll Time. That said, the two scores are not equally well evidenced: JuggernautBJJ has 499 ratings behind it against 28, so its average is the more settled of the two. Written reviews are what separate them: 93% of JuggernautBJJ's written reviews are positive against 100% of Roll Time's.

JuggernautBJJ ships an update every 5 days, Roll Time weekly. Both last shipped on October 8, 2026.
