# Sigma Mini vs BLUETTI

The clearest difference is rating: Sigma Mini at 5.0 against BLUETTI's 4.3. BLUETTI's advantage is review sentiment (66% 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 4.3. That said, the two scores are not equally well evidenced: BLUETTI 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 66% of BLUETTI'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, BLUETTI every 3 weeks. The most recent releases landed on October 1, 2026 and October 13, 2026 respectively.
