# X vs Fitnesse

The clearest difference is in-app purchases: X at none against Fitnesse's 2. X also leads on ratings volume (426 vs 46). Fitnesse's advantage is review sentiment (100% vs 75%). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Fitnesse sells 2 in-app purchases, starting at $12.99 per month. X asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for X against 5.0 for Fitnesse. That said, the two scores are not equally well evidenced: X has 426 ratings behind it against 46, so its average is the more settled of the two. Written reviews are what separate them: 75% of X's written reviews are positive against 100% of Fitnesse's.

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on September 23, 2026 and June 10, 2026 respectively.
