# IMAIOS e vs mRay

The clearest difference is review sentiment: mRay at 100% against IMAIOS e's 48%. mRay also leads on in-app purchases (none vs 2). IMAIOS e's advantage is rating (4.9 vs 3.8) and update cadence (every 9 days vs every 2 months). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. IMAIOS e sells 2 in-app purchases, starting at $21.99 per month. mRay asks for nothing beyond the download.

IMAIOS e holds the better App Store score, 4.9 against 3.8. That said, the two scores are not equally well evidenced: IMAIOS e has 1.4K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 48% of IMAIOS e's written reviews are positive against 100% of mRay's, so the app with the better star average is not the one people write more warmly about.

IMAIOS e ships an update every 9 days, mRay every 2 months. The most recent releases landed on September 23, 2026 and September 8, 2026 respectively.
