# STEP Vocabulary Builder vs Looplingo

The clearest difference is device support: STEP Vocabulary Builder at 3 against Looplingo's 1. STEP Vocabulary Builder also leads on iOS requirement (13.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. STEP Vocabulary Builder sells 3 in-app purchases, starting at $2.99 per 7 days and Looplingo sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
