Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
UltraConvert is free to download; Mini Sell costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Mini Sell holds the better App Store score, 5.0 against 4.0. Both are backed by a comparable volume of ratings — 2 and 1 respectively. Written reviews complicate that: 0% of Mini Sell's written reviews are positive against 100% of UltraConvert's, so the app with the better star average is not the one people write more warmly about.
