Science (271 programs)

Pros: Type calculations with your keyboard or use the vintage numerical onscreen keypad. Easy user interface with numerous keyboard shortcut options.

Cons: Overly simplistic, plain visual design makes for poor presentation. Still just a calculator - not anything original or new to see here.

Pros: Conversational programming. Easy to adapt to. Builds and works fast. Solid interface.

Cons: Usable only with specific mills. Doesn't support all mill types. Very slow error handling. Minimal included help.

Pros: Formatted like a regular oscilloscope. Fast fourier transform (FFT) works well. Clear and responsive display. All scope controls offered.

Cons: Not for novice users. Lacks some common oscilloscope features. No user manual. Low frequency response.

Pros: Free. Identical to the official calculator. Available offline. Gives you GRE tips.

Cons: Support needs improvement.
