Calcfolio is not just a calculator — it's a calculation notebook
Calcfolio is not just a calculator — it's a calculation notebook. Every time you tap =, Calcfolio saves that calculation automatically inside a named notebook. Label it, find it later, reuse it. Your numbers finally have context. NOTEBOOKS Create unlimited notebooks for any project or purpose — "Freelance Quote", "Renovation Budget", "Grocery Run". Every calculation lives in the right place from the moment you make it. ANNOTATE YOUR CALCULATIONS Tap any calculation in your log to add a label. Write "materials cost" next to 45 × 3. Write "monthly target" next to 12000 ÷ 30. Know what every number meant, even weeks later. FULL HISTORY Every session is saved automatically. Browse past notebooks, search by label or expression, and scroll back through your entire calculation history — nothing is ever deleted unless you choose to. REUSE PAST RESULTS Tap any result from a past notebook and use it directly in a new calculation. No more re-entering numbers you already computed. STATISTICS See how many calculations you've made today, this week, and across all notebooks. A built-in activity chart shows your calculation history at a glance. DESIGNED TO FEEL NATIVE Premium dark interface built for iOS. Smooth spring animations, haptic feedback on every key tap, and a display that scales beautifully from iPhone to iPad. PRIVATE BY DESIGN No account. No sign in. No data ever leaves your device. Everything is stored locally. WHO IT'S FOR Freelancers quoting projects. Students working through problems. Professionals tracking numbers across tasks. Anyone who has ever closed their calculator and immediately forgotten what they just worked out. Calcfolio is the calculator that remembers.
