# SQL Primer vs SQL Code Play

The clearest difference is in-app purchases: SQL Primer at none against SQL Code Play's 3. SQL Primer also leads on ads (none vs shown) and rating (3.2 vs 3.0). SQL Code Play's advantage is update cadence (every 12 months vs every 27 months). On price, device support and iOS requirement there is nothing between them.

Both are free to download. SQL Code Play sells 3 in-app purchases, starting at $0.99 per month. SQL Primer asks for nothing beyond the download.

SQL Primer holds the better App Store score, 3.2 against 3.0. That said, the two scores are not equally well evidenced: SQL Primer has 20 ratings behind it against 2, so its average is the more settled of the two.

SQL Primer ships an update every 27 months, SQL Code Play every 12 months. The most recent releases landed on September 15, 2026 and June 1, 2026 respectively.
