Reckive is the calculator that remembers.

Most calculators forget everything the moment you hit equals. Reckive doesn't. Every multi-step calculation is automatically saved, so nothing you've worked out ever disappears — whether you're splitting a bill, building a budget, or working through a multi-part problem for class.

HOW IT WORKS
Type your expression naturally, parentheses and percentages included, and watch the result update live as you type. Hit equals, and Reckive quietly saves the session in the background. Keep calculating, and each new step is added to that same session automatically, so your whole train of thought stays together in one place.

STAY ORGANIZED
- Save calculations with a title, category, and tags
- Add notes so you remember why a number mattered
- Mark favorites for the calculations you reference often
- Search across titles, expressions, results, tags, and notes
- Untitled saves are flagged as drafts automatically, so nothing slips through

BUILT FOR HOW YOU ACTUALLY CALCULATE
- True expression evaluation with correct order of operations
- Percentages and parentheses handled properly, every time
- Sign in with Google, Apple, or email
- Warm, tactile design with optional haptic feedback
- Light and dark themes
