Verdict

The call

The clearest difference is in-app purchases: Power Photo at none against Device System Services's 1. Power Photo also leads on ads (none vs shown) and rating (4.8 vs 4.5). Device System Services's advantage is ratings volume (394 vs 29). On price, review sentiment, update cadence and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Power Photo holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Device System Services has 394 ratings behind it against 29, so its average is the more settled of the two. Written reviews complicate that: 49% of Power Photo's written reviews are positive against 52% of Device System Services's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 4 months. The most recent releases landed on October 23, 2026 and October 21, 2026 respectively.
