The clearest difference is rating: Tresta at 4.7 against ULTATEL Hub's 3.2. ULTATEL Hub's advantage is review sentiment (29% vs 17%) and device support (3 vs 1). On price, ratings volume, 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.
Tresta holds the better App Store score, 4.7 against 3.2. Both are backed by a comparable volume of ratings — 12 and 10 respectively. Written reviews complicate that: 17% of Tresta's written reviews are positive against 29% of ULTATEL Hub's, so the app with the better star average is not the one people write more warmly about.
Tresta ships an update every 4 weeks, ULTATEL Hub monthly. Both last shipped on October 24, 2026.
