Tailored to Your Research Needs
Every lab has its own way of working. That's why we've made PeptideCalc incredibly flexible, with support for every common peptide unit from mg and mcg to ng, pg, and IU. Choose exactly which units you want to see and hide the rest to keep your interface clean and focused.
Work with multiple syringe types? We've got you covered with support for U-100, U-50, U-40, and even custom configurations. Save your preferred settings as defaults, and the app adapts to your workflow – not the other way around. Plus, with Dark, Light, and System modes, your eyes will thank you during those late-night lab sessions.


Built for Professional Research
We understand the demands of professional research. That's why we've built in support for specialized calculations like bacteriostatic water and ensure precise measurements every time with our carefully crafted algorithms. Work offline with confidence – no internet connection required.
Your feedback drives our continuous improvements. Regular updates mean you'll always have access to the latest features and refinements. And because we believe in keeping things simple, there are no ads to distract you and no sign-up required. Just download and start calculating.

Really loving this app. Now I can easily track all my peptides in on place! 5 Stars!! I tried a few others (iOS and web based) but they all were either missing something I wanted or the UI was lame. Loving this app.
