# TTFA Academy vs Data Engineer Pro Prep

The clearest difference is update cadence: Data Engineer Pro Prep at every 3 weeks against TTFA Academy's every 7 months. Data Engineer Pro Prep also leads on iOS requirement (13.0 vs 15.1). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. TTFA Academy sells 10 one-off in-app purchases and Data Engineer Pro Prep sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
