Help with your canvas
A little help.
More room to think.
CalcCanvas is a visual calculator for iPhone and iPad running iOS or iPadOS 17 or later.
Email info@sdilejslunce.cz. Include your device model, operating-system version, and a short description of the problem. Only attach a canvas or screenshot if you are comfortable sharing its contents.
Start a calculation
Create an empty canvas from the library, then add your first number or expression. Tap an existing number or part of a formula to edit it. Linked calculations update when their inputs change.
Find your way around
Drag the background to pan and pinch to zoom. Use Zoom to fit to see your work, or open Canvas actions → Canvas outline to reveal a specific block. Sections help organize related calculations.
Compare an alternative
Open Canvas actions → Scenarios and save the current inputs as a scenario. Changes made in that scenario keep the base inputs separate. Return to Base to see your original values; applying a scenario to the base is an explicit action.
Understand an answer
Use a formula block’s actions menu to explain its result. Canvas settings controls radians or degrees, percentage addition, and number display. Check these settings if an answer differs from what you expect. Currency labels do not fetch exchange rates or convert between currencies.
Save, share, and recover
Canvases save automatically on your device. Export an editable .calccanvas file for transfer or a separate backup, or share a PDF, image, or text report. The library’s document menu provides saved versions; restoring a version creates a copy. Local checkpoints are capped, so export important work separately.
There is no automatic iCloud sync between devices. Deleting the app removes app-controlled local storage, subject to system backup behavior. Files exported elsewhere remain in their chosen locations.
Languages
Use the library’s settings button to choose a language or follow the device language. English, German, Japanese, French, Spanish, Simplified and Traditional Chinese, Korean, Brazilian Portuguese, and Czech are supported. Your saved titles, notes, and formulas keep their original text.
Calculation limits
CalcCanvas uses finite-precision numeric values. It does not provide symbolic algebra, arbitrary precision, live exchange rates, or every possible unit conversion. Display rounding does not change stored values.
