Personal Calculator

Personal Calculator is a clean everyday math utility with a teal glass Canvas keypad. Open the app, tap Start on the splash screen, and you land on a full-viewport calculator that fills the safe area on phones, tablets, and desktop windows — portrait or landscape, without letterbox bars.

Basic mode covers the essentials: clear, sign toggle (±), percent, divide, multiply, subtract, add, decimal point, and equals. The live expression line shows what you are building while the main display shows the current value, so chained arithmetic stays readable. Tap equals to resolve the expression and keep going from the result.

Switch to Advanced when you need scientific helpers without leaving the same glass panel. Advanced adds natural log, common log, absolute value, eˣ, square root, square, reciprocal, and power (xʸ) above the familiar arithmetic rows. Mode preference is remembered on the device so you return to Basic or Advanced the way you left it.

The gear opens Settings for soft background music, soft key sound effects, and language. Eight languages ship with the app: English, Vietnamese, Traditional Chinese, Simplified Chinese, Japanese, Spanish, Hindi, and French. Labels on Basic / Advanced, Settings, Start, and Close follow the active locale. Sound toggles persist locally so a quiet session stays quiet next launch.

Controls are pointer and touch friendly. Large key hit areas, a clear equals bar, and a teal accent on operators keep the pad readable at small sizes. The display uses high-contrast mint text on a deep night field. Layout recalculates on resize so the toolbar, display, and keypad stay centered and usable when you rotate or resize the window.

Offline use: after the first load, arithmetic and settings work without a network connection. Preferences for mode, music, sound effects, and language stay on the device. No account is required to calculate.

Tips: use percent for quick discounts and tip math; toggle sign when switching between credits and balances; clear before starting a new chain if the expression line still shows a prior operator; use Advanced for logs and powers when Basic rows are not enough; mute music in Settings when you want a silent pad.

Accessibility and comfort: high-contrast display text, generous key targets, soft optional tones instead of harsh beeps, and a responsive Canvas that respects system safe-area insets on notched phones. The splash Start button is large and centered for one-thumb reach.

Marketing gallery and store screenshots match this teal glass UI — splash with Start, Basic keypad, live expression, Advanced rows, equals results, Settings with music and language, mode switch, and wide layout — so listing art matches what you see in the shipped app on tyttoot.com and stores.

Personal Calculator focuses on everyday arithmetic and optional advanced helpers in one calm night palette. It is built as an original Tyttoot Canvas utility: symbol-first branding, English marketing chrome where required, and runtime UI localized in eight languages.

Use it for shopping totals, homework checks, unit conversions you already know how to set up, and quick scientific checks when Advanced is on. Short sessions and longer desk use both fit — the pad stays readable whether the window is tall on a phone or wide on a tablet.

The product name on the store is Personal Calculator. Icons are symbol-only keypad art without ranking badges. Feature graphics and phone screenshots follow the same teal glass look as the live Canvas so there is no style gap between marketing and the app you open.

Recent changes:
1.0.13 — A small banner now shows at the bottom of menu screens only: the start screen and the Settings panel. It never shows on the keypad, so it stays out of the way while you calculate. Menus were re-spaced so buttons and text sit above the banner, nothing covered; backgrounds still fill the screen. Ads now use this app's own AdMob units for steadier loading; interstitial timing is unchanged. Basic and Advanced keypads with a live expression line work as before.
