Verdict

The call

The clearest difference is rating: Digital Electronics Quiz at 5.0 against Electronics Circuit Calculator's 4.5. Electronics Circuit Calculator's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, in-app purchases, device support and iOS requirement there is nothing between them.
