Starts and calculates
No splash ad, no progress bar: the app lands on the keypad and shows the result live while you type.
Android · German & English · works without a network
Calculating, instantly.
QuickCalc opens straight onto a working keypad, calculates locally and stays quiet: no ads, no account, no permissions.
Coming to Google Play
The app is in review — the link will appear here.
What it does
The everyday calculator without the ballast: operator precedence, brackets, percent, sign change — and the things you need daily, without hunting for them.
Completely offline
The app does not even hold the internet permission. It cannot send anything, even if it wanted to.
History with timestamps
Every calculation stays in a list, newest first. Tap an entry to keep calculating, delete single entries or all of them.
Memory keys
MC, MR, M+ and M− like a pocket calculator — an active memory is visibly marked.
Numbers your way
“.” or “,” as decimal separator, thousands separator of your choice, rounding to 0, 1 or 2 places — the number is shown for example as 1 234.50.
Light and dark
Material 3, following the system or your own choice. Both stay readable.
The four everyday tools
Short paths for the cases that would otherwise need a scrap of paper and some mental arithmetic.
Tip & split the bill
5, 10, 15, 20 per cent or your own rate, split evenly between people — per person or with the remainder.
Percentage
X% of Y, X as a percentage of Y, increase and decrease — three questions, one screen.
Discount
What is left to pay after a percentage or fixed discount, including the amount saved.
VAT
Net to gross and back, with your own default rate (8.1% out of the box) — set it once and reuse it.
A look inside
Material 3, large digits, everything reachable with one hand. The screenshots show light mode; the app follows the system.
What is deliberately missing
QuickCalc is small because it leaves things out. Those are decisions, not unfinished corners.
No network, no ads, no account
The app contains no networking code and asks for no permission at all. History and settings live on the device only. There is nothing to sync, nothing to measure and nothing to sell.
- No scientific keypad. If you need sine, roots or logarithms, this is the wrong app.
- No currency or unit conversion. That needs rate tables — and those need updates from the network.
- No account, no cloud. If you want your history on a new phone, it cannot be transferred.
- No premium tier. There is nothing to unlock and nothing to buy.
Common questions
Answered briefly — technically accurate, not promotional.
Why does the app request no permissions?
Because it does not need any. Calculating, history and settings happen locally; there is no code path that reaches the network. That is also why the Play entry says “no data collected”.
Where is my history stored?
In a local database inside the app's storage. It disappears with the app if you uninstall it. No backups happen — not even by us.
Which languages are available?
German and English, both complete. The app follows the device language; number and date formatting follow your region rather than a hard-coded rule.
Can I reuse a calculation from the history?
Yes. Tapping an entry puts its result back into the keypad so you can carry on calculating.
How exact is the arithmetic?
Decimal, with operator precedence and brackets. The value is rounded for display only; calculations continue with the full precision.
Will the calculator cost money later?
No. QuickCalc is free and stays free; there is no premium tier, no subscription and no in-app purchase.
