# SPI vs SpiritData

SPI and SpiritData both sit at 5.0 stars, but that hides the real split: 100% of SpiritData's written reviews are positive against 60% of SPI's. SpiritData also leads on iOS requirement (13.0 vs 17.0). SPI's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases).
