CalDaily: Calculator & Themes

Every result you keep can be named, tagged and found again. Eight advanced tools, a Home Screen widget, and one hundred themes — all working entirely on your device.

A calculator you will actually keep using, because it remembers the thinking behind each number.

Most calculators forget the moment you close them. CalDaily keeps every result, and lets you give it a name and a type, so a week later you can search for the dinner you split or the loan you compared instead of trying to reconstruct it. History groups itself by day, filters by tool, and exports to CSV when you need it in a spreadsheet.

Eight advanced tools cover the everyday maths that a plain keypad makes awkward: memory, scientific functions, discount and tax, tip and split, unit conversion, date differences and business days, loan payments, and trip fuel cost. Each one opens with the defaults you set once, so you are not retyping the same tax rate or party size every time.

The Home Screen widget runs the calculator without opening the app, and matches whichever theme you are using.

One hundred themes are built into the app, from quiet ceramics to deep prisms, each with its own key shape, material and light. One is free, and a single purchase unlocks the rest along with unlimited use of every advanced tool. There is no subscription.

Everything happens on your device. There is no account, no cloud sync, no advertising and no analytics. Your calculations stay with you.

Fully localized in 50 languages, with layouts that hold up in every one of them.

Who it is for: anyone who splits bills, checks discounts, converts units for recipes or DIY, plans dates and deadlines, compares loan options, or simply wants a calculator that looks like it belongs on their Home Screen.
