# AutoCode vs NASTF

The clearest difference is rating: AutoCode at 4.7 against NASTF's 3.7. AutoCode also leads on ratings volume (102 vs 6) and review sentiment (81% vs 67%). NASTF's advantage is monetization model (free vs paid) and update cadence (every 3 weeks vs every 2 months). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

AutoCode holds the better App Store score, 4.7 against 3.7. That said, the two scores are not equally well evidenced: AutoCode has 102 ratings behind it against 6, so its average is the more settled of the two. Written reviews point the same way: 81% of AutoCode's written reviews are positive against 67% of NASTF's.

AutoCode ships an update every 2 months, NASTF every 3 weeks. The most recent releases landed on October 2, 2026 and September 27, 2026 respectively.
