Everything you need to know about personal cycle analysis for your health app
Ever wonder why some days you're full of energy and others you can barely get out of bed? Those are your biorhythms - natural cycles that affect your body, emotions, and intellect. Our Biorhythm API tracks these three cycles (physical 23 days, emotional 28 days, intellectual 33 days) to tell you when you're in peak form. Think of it like a weather forecast for your body - instead of rain or sunshine, it predicts your energy levels, mood, and mental clarity. It's super fast (under 500ms) and platforms using it see 42% more engagement because users trust the personalized advice.
Biorhythms work with simple cycles based on your birth date.
Physical cycle (23 days): your body energy, stamina, and strength.
Emotional cycle (28 days): your mood, creativity, and sensitivity.
Intellectual cycle (33 days): your mental focus, memory, and decision-making.
Each cycle rises and falls in a sine wave pattern.
When a cycle is high, you're in beast mode in that area.
When it's low, it's time to take it easy.
Our API calculates where each cycle stands on any date, shows you critical days (when a cycle switches from positive to negative), and predicts your best days for workouts, important decisions, or romantic dates.
Generic wellness advice is like telling everyone to work out at 6am - it ignores that some people are night owls and others are early birds.
Biorhythm analysis goes further: it tells you specifically when YOUR body is ready for intense workouts, when YOUR mind is sharpest for difficult tasks, when YOUR emotions need extra care.
Apps using our Biorhythm API report 42% more engagement because the recommendations actually work.
Instead of "Do yoga today" (which you ignore), you get "Your physical cycle is low - perfect day for gentle yoga and recovery" (which actually makes sense).
Integrating our Biorhythm API takes about 20 minutes if you know what you're doing.
First, grab an API key (instant, no waiting).
Then make a POST request with user birth date.
We send back JSON with current values of the 3 cycles, upcoming critical days, and timing recommendations.
Want to send notifications? Use our webhook feature - we'll ping your server when a user's cycle is high for movement or low for rest.

Most developers implement it in under an hour.
