Frequently Asked Questions
How do I start a voice calculation?
Tap the microphone button and start speaking your numbers and operations naturally. The app listens continuously -- just say numbers followed by operations like "5 plus 27 plus 35000".
What does the "Read" button do?
Tap "Read" to hear your full calculation list read back to you. This lets you verify every entry without looking at the screen -- perfect for catching mistakes.
How do I add tax to my calculation?
Just say "plus tax" or "tax" during a calculation. You can set your tax rate in Settings. The app will automatically apply the percentage to your current total.
How do I export my calculations?
Tap the share icon at the top of the calculator. You can export as CSV (for Excel/Google Sheets) or plain text (for notes and messages).
How do I copy the result quickly?
Long-press the result number at the bottom of the screen. It will be copied to your clipboard instantly.
Can I see my previous calculations?
Yes! Tap the history icon (clock) at the top right. You'll see a full audit trail of all past calculations with timestamps.
What's the difference between Basic and Scientific mode?
Basic mode follows standard left-to-right calculation (1 + 2 × 3 = 9). Scientific mode respects mathematical order of operations (1 + 2 × 3 = 7).
