# Device System Services vs Test Pro

The clearest difference is rating: Device System Services at 4.5 against Test Pro's 3.6. Device System Services also leads on review sentiment (52% vs 13%) and monetization model (free with in-app purchases vs subscription). Test Pro's advantage is ads (none vs shown) and iOS requirement (10.0 vs 16.6). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. Device System Services sells 1 one-off in-app purchase and Test Pro sells 6 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Device System Services holds the better App Store score, 4.5 against 3.6. That said, the two scores are not equally well evidenced: Device System Services has 394 ratings behind it against 70, so its average is the more settled of the two. Written reviews point the same way: 52% of Device System Services's written reviews are positive against 13% of Test Pro's.

Both ship on a similar rhythm, roughly every 4 months. The most recent releases landed on October 21, 2026 and October 20, 2026 respectively.
