Export to PDF or Excel. ACCOUNT AND SYNC (NEW) Optional account with email, Apple or Google sign-in. Sync your lab notebook, calculation history and validation projects across your devices. The app stays fully usable without an account. ABBREVIATION GLOSSARY Tappable explanations for 131 scientific abbreviations. Tap any blue abbreviation in any module to learn its meaning: LOD, LOQ, Cmax, AUC, ddCt, pI, kcat and more. BILINGUAL Turkish and English all modules, reports, and glossary. REPORTING PDF (with automatic citation block useful for publications), Excel, JSON export. One-tap image sharing. PRIVACY AND ADS The app works fully without an account, and your calculations run on your device. Create an account only if you want cloud sync - then your lab notebook, calculation history and validation projects are stored on our servers so your devices stay in sync. The free version is supported by ads. Ads use a device advertising identifier and usage data, and this data may be shared with advertising partners. Pro removes all ads. You can delete your account and all synced data at any time from Settings, or at https://chembiocalc.com/delete-account PRO SUBSCRIPTION Unlimited calculations, all Pro tools (HPLC suite, Method Validation, PopPK, NGS Coverage, etc.), Lab Notebook Pro, ad-free experience.
