Verdict

The call

The clearest difference is in-app purchases: ZNotePad at none against Gamepad Doctor's 1. ZNotePad also leads on ads (none vs shown). Gamepad Doctor's advantage is update cadence (every 2 days vs every 2 months). On price, device support and iOS requirement there is nothing between them.
