# IU Mobile vs Pi

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.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Pi holds the better App Store score, 4.9 against 3.9. That said, the two scores are not equally well evidenced: IU Mobile has 187 ratings behind it against 34, so its average is the more settled of the two. Written reviews point the same way: 36% of IU Mobile's written reviews are positive against 100% of Pi's.

IU Mobile ships an update monthly, Pi every 10 days. The most recent releases landed on September 5, 2026 and September 20, 2026 respectively.
