Features & Capabilities

BiorhythmΩ is a Chrome extension that visualizes your daily biorhythms across four cycles—Physical, Emotional, Intellectual, and Intuitive. Each cycle is calculated from days lived and shown as a value from -100 to +100, with clear graphs and instant numeric feedback. Switch dates easily to look at past, present, or future rhythms and use the visuals to plan activities with a better sense of your energy, mood, and performance. The tool emphasizes accuracy with formal algorithms and a clean, easy-to-read presentation, designed for use in study, sport, work, and daily decision-making.

Multi-user support lets you manage several profiles within one extension and compare rhythms across people. You can view a 31-day analysis, extract dates for state classification, and compute averages with the Union feature. Share biorhythm insights via messages or email, and access usage information, help, and contact options directly from the app. This extension aims to provide practical, data-driven insights for everyday life, while remaining a personal planning aid rather than medical advice.

Am so glad you guys make this app so easy to use 👌

I’ve been a believer in biorhythm since the 70s and this app is so versatile and useful. I sometimes don’t use it for days and then notice I’m forgetful, clumsy, etc. and then after looking up the chart I see why it could be. The same goes for the days that I feel more in tune and positive, energetic, the rhythms are high.
