From saving calculations with tags to syncing your history across devices via Google Drive — EverCalc is designed for people who actually need their math history.
Every feature is designed to save you time and keep your calculations organized.
Every calculation you make can be saved with a custom title, category, tags, notes, and a favourite flag. No more scribbling numbers on paper or losing important results. Your entire calculation history is always at your fingertips.
Your calculations are too important to live on just one device. With EverCalc Pro, export your entire database to Google Drive and import it anywhere. Switching phones? Restore everything in seconds.
Complex calculations often span multiple steps. EverCalc captures each step within a single organized session. First, a save prompt appears. After that, every new step is silently appended — no repeated interruptions.
Tapped "Save Later" because you were in a rush? EverCalc saves it instantly as an untitled draft, marked with a 📝 Draft badge. Come back later to add a title, category, and tags at your own pace.
Changing phones should not mean losing your calculation history. Export your EverCalc database to Google Drive, install the app on your new device, sign in, and import. Everything is restored exactly as it was.
EverCalc uses a real mathematical parsing engine — not simple chain calculation. Type natural expressions like "250 + 15%" or "(50 + 10) × 3" and get accurate results following PEMDAS rules, with a live result preview.
Authentication, themes, haptics, analytics — every aspect of EverCalc is built to a premium standard.
