# OptionPosition+ vs Black

The clearest difference is rating: OptionPosition+ at 4.0 against Black's 3.0. OptionPosition+ also leads on ratings volume (20 vs 5). Black's advantage is in-app purchases (none vs 3) and review sentiment (100% vs 84%). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. OptionPosition+ sells 3 in-app purchases, starting at $2.99 per month. Black asks for nothing beyond the download.

OptionPosition+ holds the better App Store score, 4.0 against 3.0. Both are backed by a comparable volume of ratings — 20 and 5 respectively. Written reviews complicate that: 84% of OptionPosition+'s written reviews are positive against 100% of Black's, so the app with the better star average is not the one people write more warmly about.
