app to split a dinner bill with tip and still find the math a week later

CalDaily — A calculator you will actually keep using, because it remembers the thinking behind each number. Splitting a bill at the table is easy; the hard part comes a week later when someone asks what they paid — and the built-in calculator remembers nothing — CalDaily is built for this.

Short answer

CalDaily's Tip & Split tool remembers your usual party size and tip percentage, works from a Home Screen widget without opening CalDaily, and lets you name the result — 'Friday dinner' — so it is searchable later, with history grouped by day, filterable and exportable to CSV.

Be clear about what it is not: CalDaily is not an expense-splitting or IOU tracker — it keeps the calculation and its result, it does not track running balances between people. If you need that, use a dedicated shared-expenses tool; CalDaily fits the person who settles at the table and just wants the maths to survive. Free to try with three free results per tool; a single one-time purchase unlocks unlimited use, with no account and no subscription.

What to look for before choosing

  • Tip and split defaults that remember last time's party size.
  • A Home Screen widget that does the maths without opening the app.
  • Named, searchable results grouped by day.
  • CSV export if the group wants the record.
  • One-time unlock, no account — and no pretence of debt tracking.

A practical decision process

  1. Set your usual tip percentage and party size once.
  2. Split from the widget at the table.
  3. Name the result after the dinner before you pocket the phone.
  4. Search it when the question comes back a week later.
  5. Settle up in person — this app keeps maths, not balances.

Where CalDaily fits

CalDaily fits the designated bill-splitter who settles on the spot and wants the calculation findable later — not someone tracking balances between friends over time.

FAQ

Is this like a shared-expenses or IOU app?

No — it keeps the calculation and its named result, not running balances. If you need to track shared expenses between friends over time, use a dedicated tool for that.

Do I have to open the app every time?

No — the Home Screen widget calculates directly and follows the active theme.

What does the purchase unlock?

Each tool gives three free results and one theme is free; a single one-time purchase unlocks the rest — no subscription, no account.
