CMCalc vs Periodic Table & Chem Balancer
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
CMCalc
This app emulates a classic 1980s computer math calculator, offering decimal arithmetic, binary conversions, and logic functions. It supports parentheses for complex calculations and includes modern features like copy/paste and landscape mode.
- Decimal arithmetic
- Binary conversions (decimal, binary, octal, hexadecimal)
- Binary logic functions
- Operator grouping with parentheses
- Hexadecimal input (A-F)
- Copy and paste results/functions
- Landscape mode

The CMCalc application is a replica of the Casio CM-100 Computer Math Calc solar powered calculator that was sold in the mid 1980’s. It performs simple decimal arithmetic and basic binary conversions (decimal - binary - octal - hexadecimal) and binary logic functions. While it is a standard infix calculator, it supports operator grouping with parentheses. For hexadecimal calculations, the input keys include A through F. CMCalc application performs all the same functions as the calculator, and has the same look as the original. There are a couple features that were not conceivable in the 1980’s on a calculator … such as the ability to copy and paste the results or the entered function, and a landscape mode for devices with 4 inch or larger screens. The face of the calculator can be viewed in two modes including a traditional application style, and a photo replica of the original calculator face.

Verdict
The clearest difference is rating: Periodic Table & Chem Balancer at 5.0 against CMCalc's 4.6. Periodic Table & Chem Balancer also leads on update cadence (every 20 months vs every 45 months). CMCalc's advantage is ratings volume (7 vs 1) and iOS requirement (12.0 vs 15.6). On price, ads, in-app purchases and monetization model there is nothing between them.
