Heatmap Studio shows a table of numbers as a color heatmap. You can start from a blank grid, paste a table, or import a CSV or TSV file. You can edit cells and labels, choose colors, and view basic figures such as the minimum, maximum, and average. Projects are stored in the app on this device. You can export a PNG image or a CSV file. The colors are there to help you view the numbers. Please check important numbers yourself.

Verdict
The clearest difference is in-app purchases: Heatmap Studio at none against Dyslexia Notes's 2. Dyslexia Notes's advantage is ads (none vs shown) and update cadence (every 3 months vs every 12 months). On price, device support and iOS requirement there is nothing between them.
