Verdict

The call

The clearest difference is rating: BlueGrays at 4.2 against Arduino Programming Tutorial's 3.0. BlueGrays also leads on ads (none vs shown) and update cadence (every 5 days vs every 6 weeks). Arduino Programming Tutorial's advantage is in-app purchases (none vs 6). On price, device support and iOS requirement there is nothing between them.
