Verdict
The clearest difference is monetization model: Silver Fox BJJ at free with in-app purchases against JuggernautBJJ's subscription. JuggernautBJJ's advantage is ratings volume (499 vs 18) and update cadence (every 5 days vs fortnightly). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. JuggernautBJJ sells 1 in-app purchase, starting at $19.99 per month and Silver Fox BJJ sells 3 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.
JuggernautBJJ holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: JuggernautBJJ has 499 ratings behind it against 18, so its average is the more settled of the two. Written reviews point the same way: 93% of JuggernautBJJ's written reviews are positive against 80% of Silver Fox BJJ's.
JuggernautBJJ ships an update every 5 days, Silver Fox BJJ fortnightly. The most recent releases landed on October 19, 2026 and September 30, 2026 respectively.
