# Pacific Fire vs Sigma Theory

The clearest difference is in-app purchases: Pacific Fire at none against Sigma Theory's 7. Pacific Fire also leads on review sentiment (87% vs 58%) and ratings volume (152 vs 8). Sigma Theory's advantage is update cadence (fortnightly vs every 6 weeks) and iOS requirement (13.0 vs 15.6). On ads, monetization model and device support there is nothing between them.

Pacific Fire costs $5.99 and Sigma Theory $6.99 up front. Sigma Theory sells 7 one-off in-app purchases. Pacific Fire asks for nothing beyond the download.

Pacific Fire holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Pacific Fire has 152 ratings behind it against 8, so its average is the more settled of the two. Written reviews point the same way: 87% of Pacific Fire's written reviews are positive against 58% of Sigma Theory's.

Pacific Fire ships an update every 6 weeks, Sigma Theory fortnightly. The most recent releases landed on September 28, 2026 and September 10, 2026 respectively.
