About Dablew Tools

Dablew Tools makes simple, fast calculators that help students track and plan their grades — your GPA, the score you need on a final, and your current weighted class grade. It is built and maintained by Dablew Devs.

What makes us different

• Fast. Pages are lightweight and load almost instantly, even on a phone.
• Private. All calculations run in your browser — we never send your grades to a server or store them.
• Free. No sign-up, no paywall. The site is supported by unobtrusive display ads.

A note on accuracy

Our calculators use standard grading formulas and common scales. Schools vary, so always confirm important results against your institution's official policy or registrar.
