# SIMO vs Learn to Code

The clearest difference is price: Learn to Code at Free against SIMO's $4.99. Learn to Code also leads on rating (4.9 vs 4.2) and ratings volume (601 vs 55). SIMO's advantage is in-app purchases (none vs 10) and iOS requirement (14.0 vs 16.0). On update cadence, ads and device support there is nothing between them.

Learn to Code is free to download; SIMO costs $4.99 up front. Learn to Code sells 10 one-off in-app purchases. SIMO asks for nothing beyond the download.

Learn to Code holds the better App Store score, 4.9 against 4.2. That said, the two scores are not equally well evidenced: Learn to Code has 601 ratings behind it against 55, so its average is the more settled of the two. Written reviews point the same way: 58% of SIMO's written reviews are positive against 71% of Learn to Code's.

SIMO ships an update every 3 weeks, Learn to Code every 6 weeks. Both last shipped on September 29, 2026.
