Verdict
The clearest difference is review sentiment: Pi at 100% against IU Mobile's 36%. Pi also leads on rating (4.9 vs 3.9) and update cadence (every 10 days vs monthly). IU Mobile's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, in-app purchases and device support there is nothing between them.
