# BCAA vs Surge

The clearest difference is price: BCAA at Free against Surge's $2.00. BCAA also leads on ratings volume (6 vs 1). Surge's advantage is in-app purchases (none vs 6). On rating, update cadence, ads and device support there is nothing between them.

BCAA is free to download; Surge costs $2.00 up front. BCAA sells 6 in-app purchases, starting at $3.99 per month. Surge asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for BCAA against 5.0 for Surge. That said, the two scores are not equally well evidenced: BCAA has 6 ratings behind it against 1, so its average is the more settled of the two.

BCAA ships an update every 3 weeks, Surge fortnightly. The most recent releases landed on November 2, 2026 and November 9, 2026 respectively.
