# Deviapp vs Device Monitor

The clearest difference is rating: Deviapp at 4.5 against Device Monitor's 3.4. Deviapp also leads on ratings volume (477 vs 11) and iOS requirement (12.2 vs 16.0). Device Monitor's advantage is ads (none vs shown) and update cadence (monthly vs every 3 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Deviapp sells 2 in-app purchases, starting at $9.99 per 7 days and Device Monitor sells 5 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Deviapp holds the better App Store score, 4.5 against 3.4. That said, the two scores are not equally well evidenced: Deviapp has 477 ratings behind it against 11, so its average is the more settled of the two.

Deviapp ships an update every 3 months, Device Monitor monthly. The most recent releases landed on November 3, 2026 and November 8, 2026 respectively.
