# Fill vs Crack the Code

The clearest difference is in-app purchases: Crack the Code at none against Fill's 1. Crack the Code also leads on ads (none vs shown). Fill's advantage is update cadence (every 6 days vs every 2 weeks) and iOS requirement (12.0 vs 15.1). On price, rating, review sentiment and ratings volume there is nothing between them.

Both are free to download. Fill sells 1 one-off in-app purchase. Crack the Code asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for Fill against 5.0 for Crack the Code. Both are backed by a comparable volume of ratings — 3 and 4 respectively. Written reviews split almost evenly too, at 100% and 100% positive.

Fill ships an update every 6 days, Crack the Code every 2 weeks. The most recent releases landed on November 4, 2026 and November 5, 2026 respectively.
