SPI is free to download; Ghost Hunter M2 costs $7.99 up front. SPI sells 4 in-app purchases, starting at $4.99 per month. Ghost Hunter M2 asks for nothing beyond the download.

SPI holds the better App Store score, 5.0 against 4.6.

Written reviews complicate that: 73% of Ghost Hunter M2's written reviews are positive against 60% of SPI's, so the app with the better star average is not the one people write more warmly about.
