# Devmaxx vs Variance

The clearest difference is review sentiment: Variance at 100% against Devmaxx's 21%. Variance also leads on rating (5.0 vs 4.4) and monetization model (freemium vs subscription). Devmaxx's advantage is ratings volume (495 vs 5) and iOS requirement (17.5 vs 26.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Devmaxx sells 2 in-app purchases, starting at $8.99 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 4.4. That said, the two scores are not equally well evidenced: Devmaxx has 495 ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 21% of Devmaxx's written reviews are positive against 100% of Variance's.

Both ship on a similar rhythm, roughly every 2 weeks. The most recent releases landed on September 22, 2026 and September 12, 2026 respectively.
