Tabulo – Multi-Tab Calculator

The Code Cipher

Bu ilova haqida

Tabulo is a simple, classic calculator with one big difference: tabs.

Keep separate calculations open side by side – groceries in one tab, rent in another, a trip budget in a third – and switch between them with a swipe. Need a result from one tab in another? Insert it as a linked value. Change the original and everything that uses it updates automatically.

MULTIPLE TABS
• Open as many calculations as you need and give each a name and a note
• Swipe the display to move between tabs
• Each tab keeps its own history, saved even after you close the app
• Rename, reorder, duplicate or share any tab

LINKED RESULTS
• Use the result of one tab inside another, e.g. Total = Groceries + Rent
• Linked values update live when the source tab changes
• Loops are prevented, and closing a tab never silently breaks the others

SEE AND EDIT EVERYTHING
• The whole calculation is always on screen, not just the last number
• The answer appears as you type
• Tap anywhere in the calculation to move the cursor and fix a digit
• Undo and redo every change – even after pressing C

ACCURATE BY DESIGN
• Exact decimal math: 0.1 + 0.2 = 0.3, and money adds up to the cent
• Standard order of operations, with a view that shows how your calculation was grouped
• Clear, predictable percent: 200 + 10% = 220, 200 − 10% = 180, 10% × 200 = 20
• Plain error messages instead of mysterious results

SCIENTIFIC WHEN YOU NEED IT
• sin, cos, tan and their inverses, in degrees or radians
• Square and cube roots, powers, ln, log, factorial, π and e
• Tucked away behind one button, so the keypad stays simple

COMFORTABLE TO USE
• Big, clear keys and a one-handed keypad mode
• Light and dark themes
• Number format that follows your region (1,234.5 or 1.234,5)
• Copy results and paste numbers from other apps
• Optional vibration on key press

PRIVATE AND OFFLINE
• No ads. No account. No tracking.
• Works completely offline – the app doesn't even have internet access
• Your calculations are stored only on your phone

Tabulo: many calculations, one calculator.
