CalcES Notebook is a free online notebook made by MathDa for phone and computer. Its math lines are formulas that compute the same answers as the scientific calculator. Notes stay in the browser where you write them; move them by exporting a file and importing it elsewhere.
CalcES Notebook keeps an exercise's givens, explanations and calculations together in one note. Use it as a notepad for working through a problem: add a heading, an image of a diagram, or two columns labeled Given | Solution. Put related formulas in a frame to keep a formula sheet together.
On the scientific calculator, press the Note button to save the current expression into your note, or choose Save to notebook on a History entry. You can also open a note's formula in the calculator, or copy and adapt a physics or chemistry template.
Named values let a formula sheet recalculate when an input changes. For a spring exercise, define k and m, then write ω = √(k/m). Change either input and the value of ω updates.
Tap a result to switch between fraction or root form and decimal form where available. Each note keeps its own angle unit, such as degrees or radians. Add a unit label beside a result.
The phone's math keyboard has fractions, roots, powers, functions, Greek letters and names defined earlier in the note. Text lines use your phone's usual keyboard; on a computer, type formulas directly or open the floating math keyboard.
CalcES Notebook saves notes automatically in the browser on the device where they are written. Export a note or all your notes to keep a copy. Clearing the browser's site data erases notes you have not exported.
