# SPI vs EOTU

The clearest difference is rating: EOTU at 5.0 against SPI's 4.1. EOTU also leads on review sentiment (100% vs 59%) and in-app purchases (none vs 4). SPI's advantage is ratings volume (11 vs 2). On price, update cadence, ads and monetization model there is nothing between them.

Both are free to download. SPI sells 4 in-app purchases, starting at $4.99 per month. EOTU asks for nothing beyond the download.

EOTU holds the better App Store score, 5.0 against 4.1. That said, the two scores are not equally well evidenced: SPI has 11 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 59% of SPI's written reviews are positive against 100% of EOTU's.

Both ship on a similar rhythm, roughly every 5 weeks. The most recent releases landed on November 4, 2026 and October 30, 2026 respectively.
