# Marina Protocol vs SINNTS

The clearest difference is rating: SINNTS at 5.0 against Marina Protocol's 4.2. SINNTS also leads on ads (none vs shown) and update cadence (every 6 days vs every 3 weeks). Marina Protocol's advantage is ratings volume (18 vs 2). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Marina Protocol sells 10 one-off in-app purchases and SINNTS sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

SINNTS holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: Marina Protocol has 18 ratings behind it against 2, so its average is the more settled of the two.

Marina Protocol ships an update every 3 weeks, SINNTS every 6 days. The most recent releases landed on September 29, 2026 and October 6, 2026 respectively.
