WHAT MAKES AYKO CALC DIFFERENT

• TRANSPARENT: every calculator shows Formula, Step-by-step, When to use, Why, Pitfalls and Reference. You see exactly what the number means.
• PATIENT MODE: enter age, weight, height, creatinine and blood pressure once; all relevant calculators are pre-filled across the session.
• CUSTOM CALCULATORS: write your own formula in a sandboxed editor; save, organize and share via JSON.
• OFFLINE: every calculation runs on-device; no account needed and your inputs never leave your phone.
• BILINGUAL: full English and Turkish, instantly switchable, follows device language.
• DARK MODE: system-aware light/dark theme.

AYKO Calc is free, supported by a single, unobtrusive banner on the home screen - never inside a calculation.
