Common questions
Do I need an account?
Winston Scientific works without sign-in or account creation.
Does the app need the internet?
No. The calculator, grapher, Function Lab, unit converter, constants library, statistics, formula library, and history all work fully offline.
How do I switch between degrees and radians?
Tap the angle-mode pill in the top-left of the Calc, Graph, or Function Lab screens to cycle RAD → DEG → GRAD. You can also set it in Settings. Radians is the default so calculus results in Function Lab match the standard convention; if your trig answers look off, check this badge first.
Where are the unit converter and constants?
Open the Tools tab. It contains the Unit Converter (17 categories, 140+ units), the Physical Constants library (45 CODATA 2022 constants you can tap to insert or copy), Statistics, and Settings.
How does the Study tab work?
The Study tab is a searchable library of 68 formulas. Formulas marked with a function icon open a live mini-solver you can fill in to compute a result.
Where do the constants and conversion factors come from?
Physical constants use NIST CODATA 2022 recommended values and unit-conversion ratios use the defined values in NIST SP 811. Both are bundled in the app.
