PepCalc is an incredibly useful tool for anyone working with peptides. The calculator is accurate, versatile, and covers multiple syringe options, which makes experiments much easier. I really like the ability to save and edit calculations, add notes, and even export results as PDFs. The peptide library and reconstitution guide are great resources, and the light/dark mode option makes it comfortable to use anytime. A must-have app for research and learning!

I purchased the subscription version as this looked good yet app still says free, no code no nothing. Developer reached out and after a few emails the issue has been sorted and I am now very happy with the app, just what I was looking for
