Two-variable systems work too. Would appreciate the ability to save solved equations for later. ### 4/5 — Helpful for studying *2026-06-01* Used this through my entire stats course. Scientific functions are reliable. Equation solver helped me check my work. Needs a fraction input mode. ### 4/5 — History is a lifesaver *2026-06-01* Being able to scroll back through past calculations saves me time. Wish I could pin specific entries or star them for quick reference. ### 4/5 — Works locally and fast *2026-05-31* No internet needed for core functions which is great. Scientific calculator is reliable. History stores everything locally. Would appreciate iCloud sync for history. ### 4/5 — No login, just calculate *2026-05-31* Love that no sign-up is required. Everything works offline. Programmer calc handles binary conversions smoothly. Wish results showed in all bases at once. ## Frequently asked questions about CalcNest ### What calculation functions does CalcNest offer?
