calculator app that remembers my tax rate and keeps named history for invoices
CalDaily — A calculator you will actually keep using, because it remembers the thinking behind each number. The built-in calculator makes you re-type the tax rate every time, and last week's quote evaporates the moment you close it — what a freelancer needs is memory, not more buttons — CalDaily is built for this.
Short answer
CalDaily's Discount & Tax tool stores your defaults, so your local VAT or sales-tax rate is set once and reused; seven more advanced tools cover tip and split, unit conversion, date differences and business days, loan payments and trip fuel cost. Every result can be named, typed and searched later; history is grouped by day, filterable by tool, and exports to CSV for a spreadsheet.
One theme is free and each advanced tool gives three free results, so you can test the workflow before the single one-time purchase that unlocks all themes and unlimited tool use — no subscription, no account, no cloud, no ads, no analytics; everything stays on the device. It is a calculator with memory, not tax software: verify rates with your tax authority, as nothing here is tax or accounting advice.
What to look for before choosing
- Defaults that persist — set your local VAT or sales-tax rate once.
- Results you can name, type and search when the invoice question comes back.
- History grouped by day with CSV export for reconciliation.
- A one-time unlock rather than a subscription.
- On-device only: no account, cloud, ads or analytics.
A practical decision process
- Set your usual tax rate and discount as tool defaults.
- Run the quote and name the result after the client or job.
- Search the history when the invoice or reconciliation question arrives.
- Export CSV if the numbers need to reach a spreadsheet.
- Use the free results per tool to judge it before the one-time unlock.
Quick comparison
| Need | What to check | Why it matters |
|---|---|---|
| Pricing model | Check whether useful features require a subscription, a one-time unlock, or neither. | The cheapest app on day one may not be cheapest after a year. |
| Privacy model | Prefer on-device work when the content is sensitive. | Private documents, resumes, study data, and family content deserve careful handling. |
| Export / lock-in | Confirm file formats, sharing, backup, and deletion controls. | A good app should help you finish the task, not trap your work. |

FAQ
The built-in calculator is free — why pay?
If it covers you, keep it. What CalDaily sells is memory: saved defaults and a named, searchable history — not smarter arithmetic.
Does it know my country's tax rates?
No — you set your local VAT or sales-tax rate yourself as a default. Verify rates with your tax authority; this is not tax or accounting advice.
Is my history uploaded anywhere?
No — history stays on the device; there is no account, cloud sync, ads or analytics.
