Verdict
The clearest difference is rating: SMART Union at 3.3 against Prime Storage's 3.0. SMART Union also leads on ratings volume (28 vs 4). On price, review sentiment, update cadence and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
SMART Union holds the better App Store score, 3.3 against 3.0. That said, the two scores are not equally well evidenced: SMART Union has 28 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 29% of SMART Union's written reviews are positive against 32% of Prime Storage's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on August 28, 2026 and September 19, 2026 respectively.
