BlakeCalc review

Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

BlakeCalc brings scientific calculations and a freeform drawing canvas together in a mobile app for students, engineers, scientists, and others working through mathematical problems. Available for iOS and Android, it includes more than 120 built-in functions, complex-number arithmetic, matrix operations, numerical differentiation, and definite integration. Its whiteboard supports pen colors, stroke widths, an eraser, and undo, so users can sketch or annotate alongside calculations.

The range of mathematical operations is the clearest reason to consider BlakeCalc. Matrix tools cover determinants, inverses, transposes, and eigenvalues, while numerical calculus handles differentiation and definite integration. Users can also switch among degree, radian, gradian, and DMS angle handling, and decimal, hexadecimal, binary, and octal modes. A library of physical and mathematical constants, unit conversion, and calculation history adds practical support for varied work. This makes the app a fit for mobile users who want more than standard scientific functions, especially when complex numbers and matrices matter.

BlakeCalc is free, and the published product details describe no paid tier to compare. Its platform coverage is limited to mobile, so users who need a desktop calculator should look elsewhere. Google Play lists the app as containing ads, a consideration for people who prefer an ad-free interface. The whiteboard is useful for sketches and annotations, but the app is still centered on calculator functions rather than a broader study or engineering workflow. Choose BlakeCalc for a free mobile tool combining advanced operations with a drawing canvas; choose another option if desktop access is essential or ads are a concern.
