# Quant vs Variance

The clearest difference is review sentiment: Variance at 100% against Quant's 50%. Variance also leads on rating (5.0 vs 3.9) and update cadence (every 2 weeks vs every 7 months). Quant's advantage is iOS requirement (10.0 vs 26.0). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Quant sells 1 in-app purchase, starting at $1.99 per month and Variance sells 2 in-app purchases, starting at $24.99 per month. Whichever you choose, the download price is not the number that matters.

Variance holds the better App Store score, 5.0 against 3.9. Both are backed by a comparable volume of ratings — 7 and 5 respectively. Written reviews point the same way: 50% of Quant's written reviews are positive against 100% of Variance's.

Quant ships an update every 7 months, Variance every 2 weeks. The most recent releases landed on September 23, 2026 and September 30, 2026 respectively.
