# Fastival vs 16

The clearest difference is review sentiment: 16 at 100% against Fastival's 53%. 16 also leads on rating (4.0 vs 3.6). Fastival's advantage is ads (none vs shown) and ratings volume (13 vs 4). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Fastival sells 1 one-off in-app purchase and 16 sells 5 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

16 holds the better App Store score, 4.0 against 3.6. Both are backed by a comparable volume of ratings — 13 and 4 respectively. Written reviews point the same way: 53% of Fastival's written reviews are positive against 100% of 16's.

Fastival ships an update monthly, 16 every 6 weeks. Both last shipped on September 17, 2026.
