# VolFix.NET vs HeatMap

The clearest difference is in-app purchases: VolFix.NET at none against HeatMap's 3. VolFix.NET also leads on ads (none vs shown). HeatMap's advantage is ratings volume (224 vs 15) and device support (4 vs 2). On price, rating, review sentiment and update cadence there is nothing between them.

Both are free to download. HeatMap sells 3 in-app purchases, starting at $4.49 per month. VolFix.NET asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for VolFix.NET against 4.9 for HeatMap. That said, the two scores are not equally well evidenced: HeatMap has 224 ratings behind it against 15, so its average is the more settled of the two. Written reviews split almost evenly too, at 84% and 83% positive.

VolFix.NET ships an update every 3 weeks, HeatMap fortnightly. The most recent releases landed on October 14, 2026 and October 16, 2026 respectively.
