# Halm vs Data_Engineering

The clearest difference is in-app purchases: Halm at none against Data_Engineering's 1. Data_Engineering's advantage is device support (3 vs 1) and iOS requirement (17.0 vs 26.1). On price and ads there is nothing between them.

Both are free to download. Data_Engineering sells 1 in-app purchase, starting at $1.99 per month. Halm asks for nothing beyond the download.
