Verdict

The call

The clearest difference is rating: n at 4.7 against onsA440's 2.0. n also leads on update cadence (every 2 weeks vs every 5 months) and ratings volume (3.2K vs 4). onsA440's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price, review sentiment, device support and iOS requirement there is nothing between them.
