# BuilderGPT vs RailMaker

The clearest difference is iOS requirement: BuilderGPT at 15.1 against RailMaker's 26.2. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. BuilderGPT sells 5 in-app purchases, starting at $4.99 per 7 days and RailMaker sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
