# AVR Projects vs DFT 101

The clearest difference is in-app purchases: DFT 101 at none against AVR Projects's 10. On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. AVR Projects sells 10 one-off in-app purchases. DFT 101 asks for nothing beyond the download.
