Verdict

The call

The clearest difference is rating: iRock at 4.5 against e's 3.0. iRock also leads on ratings volume (511 vs 2) and update cadence (monthly vs every 2 months). e's advantage is monetization model (free vs free with in-app purchases) and review sentiment (67% vs 55%). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. e sells 3 in-app purchases, starting at $22.99 per 3 months and iRock sells 8 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

iRock holds the better App Store score, 4.5 against 3.0. That said, the two scores are not equally well evidenced: iRock has 511 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 67% of e's written reviews are positive against 55% of iRock's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

e ships an update every 2 months, iRock monthly. The most recent releases landed on October 29, 2026 and October 31, 2026 respectively.
