Verdict
The clearest difference is monetization model: BookmarkPro at free against Device Kit's freemium. BookmarkPro also leads on review sentiment (100% vs 77%). Device Kit's advantage is ratings volume (93 vs 1). On price, rating, 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. BookmarkPro sells 1 one-off in-app purchase and Device Kit sells 4 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 5.0 for BookmarkPro against 4.9 for Device Kit. That said, the two scores are not equally well evidenced: Device Kit has 93 ratings behind it against 1, so its average is the more settled of the two. Written reviews are what separate them: 100% of BookmarkPro's written reviews are positive against 77% of Device Kit's.
BookmarkPro ships an update weekly, Device Kit every 10 days. The most recent releases landed on October 30, 2026 and October 31, 2026 respectively.
