Verdict
The clearest difference is in-app purchases: BitSpinner at none against Electronic Circuit Design Quiz's 7. BitSpinner also leads on ads (none vs shown). Electronic Circuit Design Quiz's advantage is update cadence (every 3 weeks vs every 4 months) and iOS requirement (12.0 vs 26.0). On price and device support there is nothing between them.
