CalDaily: Calculator & History

CalDaily is a calculator app that remembers the thinking behind each number. Name and tag any result, search it a week later, and use eight advanced tools: scientific functions, percentages and tax, tip and split, loans, unit conversion and more, with a home screen widget and CSV export.

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. It is a calculator with history that groups itself by day, filters by tool, and exports to CSV when you need your numbers in a spreadsheet.

Eight advanced tools
Eight advanced tools cover the everyday math 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.

One calculator for everyday jobs
Use it as a tip calculator when the bill arrives, a loan calculator when you compare a car loan or a mortgage, a unit converter for recipes and DIY, or a scientific calculator for homework. Work out percentages for discounts and tax, count business days before a deadline, or estimate the fuel cost of a road trip.

Calculator widget
The home screen widget runs the calculator without opening the app, and matches whichever theme you are using.

One hundred themes
One hundred themes are built into the app, from quiet ceramics to deep prisms, each with its own key shape, material and light. One theme is free, and an in-app purchase unlocks the full version with all the other themes and unlimited use of every advanced tool.

Private by design
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.

Made for moments like these
• Splitting a dinner bill and finding the split again next week
• Comparing two loans side by side
