# HeatNext vs Noise

The clearest difference is in-app purchases: Noise at none against HeatNext's 1. Noise also leads on iOS requirement (13.0 vs 15.0). HeatNext's advantage is update cadence (every 2 months vs every 10 months). On price, ads and device support there is nothing between them.

Both are free to download. HeatNext sells 1 in-app purchase, starting at $22.90 per year. Noise asks for nothing beyond the download.

HeatNext ships an update every 2 months, Noise every 10 months. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
