Verdict

The call

The clearest difference is in-app purchases: Key at none against Touchscreen Pro's 1. Key also leads on ads (none vs shown) and iOS requirement (13.0 vs 15.6). Touchscreen Pro's advantage is update cadence (every 5 days vs every 21 months). On price and device support there is nothing between them.
