# Past Chicago vs Keymagine

The clearest difference is review sentiment: Past Chicago at 100% against Keymagine's 55%. Past Chicago also leads on in-app purchases (none vs 7). Keymagine's advantage is rating (4.8 vs 4.5) and ratings volume (295 vs 10). On price, ads and device support there is nothing between them.

Both are free to download. Keymagine sells 7 in-app purchases, starting at $4.99 per 7 days. Past Chicago asks for nothing beyond the download.

Keymagine holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Keymagine has 295 ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 100% of Past Chicago's written reviews are positive against 55% of Keymagine's, so the app with the better star average is not the one people write more warmly about.

Past Chicago ships an update monthly, Keymagine every 2 weeks. The most recent releases landed on November 1, 2026 and November 8, 2026 respectively.
