# Bowldyna Studio vs TrueLine

The clearest difference is device support: Bowldyna Studio at 3 against TrueLine's 1. Bowldyna Studio 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. Bowldyna Studio sells 1 one-off in-app purchase and TrueLine sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
