Hey makers! I built Percently (https://percently.io) because I couldn’t find a calculator that was fast, flexible and mobile-friendly. Percently gives you accurate results instantly.
It’s free, ad-lite! Would love your feedback, votes & comments. 🙏
MDBuild is a lightning-fast, privacy-first markdown editor and knowledge-base platform that brings together live preview, Mermaid diagrams, KaTeX math, export to PDF/HTML/DOCX/image, and optional cloud sync—all under one clean interface.
