Calculator Easy

Calculator Easy is a simple, accurate calculator that remembers your math. See the answer while you type, find every result again in History, add a note or a receipt photo to it, and open a mini calculator over any app.

Great for shopping, splitting bills, prices with tax or discount, budgets and everyday quick math.

HOW IT WORKS
1. Type your sum. The result shows live under it, before you press =.
2. Press =. The calculation is saved to History automatically.
3. Open History to search, add a note or photos, add results up or export them.
4. In another app? Turn on the floating calculator and tap the bubble.

CALCULATOR
• Live result while you type, with the whole expression on screen.
• Tap anywhere in the expression to move the cursor and fix a number. No need to start over.
• Real math order (× and ÷ before + and −), parentheses (missing closing ones are added for you), ± and %.
• Phone-style percent: 200 + 10% = 220, 200 × 10% = 20.
• +VAT and −% keys: add tax or take off a discount in one tap. Set your own rates in Settings (10% by default).
• Memory keys: MC, MR, M+, M−.
• fx scientific keys: sin, cos, tan (in degrees), ln, log, √, x², xʸ, π and e.
• Precise decimal math, so 0.1 + 0.2 shows exactly 0.3.
• Copy the result with the copy button or a long-press on the result.
• Clear messages instead of wrong answers: "Can't divide by zero", "Undefined", "Number is too large".
• Works with a hardware or Bluetooth keyboard.

HISTORY WITH NOTES AND PHOTOS
• Every result is saved when you press =, newest first, with the date and time.
• Write a note so you remember what a number was for: "Team lunch", "Rent split"…
• Attach photos of receipts, bills or price tags: take one with the camera or pick several from your gallery. Tap a photo to view it full screen and pinch to zoom.
• Search by expression, result or note.
• Long-press results to select them and see their total instantly. Copy the total, use it in the calculator or share the selection.
• Export your history as a CSV file (date, expression, result, note) to open in Excel or Google Sheets.
• Open any old calculation to copy it or send it back to the calculator and keep going.
• Delete one calculation or clear the whole history.

FLOATING CALCULATOR
• A calculator bubble that stays on top of any app, like a chat bubble.
• Tap the bubble to open a full keypad. Drag it anywhere; the bubble snaps to the screen edge and remembers its place.
• Tap ✕ to shrink it back to the bubble, or ↑ to open the full app.
• Results you calculate in the bubble are saved to History too.
• Turn it on from the app, from Settings or from a Quick Settings tile. Turn it off by dropping the bubble on the ✕ at the bottom of the screen, or from its notification.
• If you leave it on, it comes back after you restart your phone.

SETTINGS
• Light, dark or system theme.
• Decimal places: Auto, or 0 to 4.
• Key sound and vibration on/off.
• 8 languages: English, Spanish, French, Portuguese, Russian, Vietnamese, Indonesian and Hindi.

YOUR PRIVACY
• Your calculations, notes and photos are stored only on your phone and are never uploaded. No account needed.
• No camera or storage permission is needed: photos are taken with your camera app and chosen with the Android photo picker, only when you tap Camera or Gallery.

DISPLAY OVER OTHER APPS – WHY WE NEED IT
The floating calculator needs Android's "Display over other apps" permission to show the bubble on top of other apps. The bubble only shows the calculator. It does not read or change anything in other apps. The app asks for this permission only when you turn the floating calculator on, and a notification shows while it is on.

Premium removes all ads (banner, full-screen and app-open). History, notes, photos and the floating calculator stay free. You can manage or cancel your subscription anytime in Google Play.
