# luai5.2.1 vs C Shell

luai5.2.1 and C Shell both sit at 4.4 stars, but that hides the real split: 91% of luai5.2.1's written reviews are positive against 56% of C Shell's. luai5.2.1 also leads on monetization model (free vs free with in-app purchases). C Shell's advantage is ratings volume (63 vs 7). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. luai5.2.1 sells 7 one-off in-app purchases and C Shell sells 2 in-app purchases, starting at $4.49 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.4 for luai5.2.1 against 4.5 for C Shell. That said, the two scores are not equally well evidenced: C Shell has 63 ratings behind it against 7, so its average is the more settled of the two. Written reviews are what separate them: 91% of luai5.2.1's written reviews are positive against 56% of C Shell's.
