# Sigma Mini vs Anker Power

The clearest difference is rating: Sigma Mini at 5.0 against Anker Power's 4.5. Sigma Mini also leads on iOS requirement (11.0 vs 15.1). Anker Power's advantage is review sentiment (70% vs 38%) and ratings volume (1.5K vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Sigma Mini holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Anker Power has 1.5K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 38% of Sigma Mini's written reviews are positive against 70% of Anker Power's, so the app with the better star average is not the one people write more warmly about.

Sigma Mini ships an update every 2 months, Anker Power fortnightly. The most recent releases landed on October 1, 2026 and October 20, 2026 respectively.
