Lytes is an iPhone app developed by Free Radical Software LLC, designed to provide quick and easy access to information about the causes, symptoms, diagnosis, and treatment of electrolyte disorders. With the Lytes Selection Dial, you can easily drill down to the specific information you need within seconds.

The program's intuitive single-screen interface keeps things straightforward, making it easy to see causes, signs, diagnosis, and treatment with just a flick of your thumb. The app contains 50 pages of practical information for the wards, and Lytes remembers where you left off when you return. Additionally, it provides all disorders with a reference section that includes links to PubMed.
