Verdict
The clearest difference is in-app purchases: Shelly Switcher at none against Blue Switch's 1. Shelly Switcher also leads on ads (none vs shown) and iOS requirement (13.0 vs 18.0). Blue Switch's advantage is update cadence (every 3 months vs every 6 months). On price and device support there is nothing between them.
