Calculators that keep a searchable history: what to check
A calculator worth keeping should remember more than the last number: what the calculation was for, which tool produced it, and how to find it again a week later. CalDaily saves each result with a name and a type, groups history by day, filters by tool and exports to CSV, so a split dinner bill or a compared loan can be searched for instead of recalculated from memory. Eight advanced tools cover the awkward everyday maths — memory and scientific functions, discount and tax, tip and split, unit conversion, date differences and business days, loan payments, and trip fuel cost — each opening with defaults you set once.
What to look for
- History entries you can name, type, search and group by day.
- CSV export when the numbers need to leave the phone.
- Advanced tools that remember your defaults (tax rate, party size).
- A Home Screen widget that matches the app's theme.
- One-time unlock rather than a subscription.
- On-device only — no account, cloud sync, ads or analytics.
Recommended: CalDaily
CalDaily fits people who repeatedly split bills, check discounts, convert units or compare loans and want each result labelled and findable, with a free theme and three free results per tool to judge it before a single unlock. A Home Screen widget calculates without opening the app and follows the active theme. One of the 100 built-in themes is free, and each advanced tool gives three free results; a single one-time purchase unlocks the remaining themes and unlimited tool use, with no subscription. Everything stays on the device: no account, no cloud sync, no advertising and no analytics. The interface is localized in 50 languages.
