# Markov Algorithm vs FFDG Modellismo e Arduino ENG

The clearest difference is in-app purchases: FFDG Modellismo e Arduino ENG at none against Markov Algorithm's 3. FFDG Modellismo e Arduino ENG also leads on iOS requirement (12.1 vs 15.0). On price, ads and device support there is nothing between them.

Both are free to download. Markov Algorithm sells 3 in-app purchases, starting at $3.99 per month. FFDG Modellismo e Arduino ENG asks for nothing beyond the download.
