RhythmBio

Some days you're sharp, some days you're flat. RhythmBio charts your physical, emotional, intellectual and intuitive cycles from your birthday, so you can plan around your best days. The four classic biorhythm cycles, physical (23 days), emotional (28), intellectual (33) and intuitive (38), become one daily rhythm score, a live wave you can scrub through, and a plain-English sense of what today might suit. FREE, ALWAYS • Your daily rhythm score and day type, with the cycles lifting it and holding it back • The live wave and a 90-day forecast, with a heads-up on crossing days • A journal to log how you actually felt, and see how closely it tracks the maths • An optional morning notification PRO • An AI-written morning briefing, personal to your cycles and to how you've actually felt • Family Hub: add your partner, kids and friends, see everyone's day at a glance, and get coaching for each person, from what to say today to handling a crossing day • Calendar scoring: link your calendar and every upcoming event is rated against your rhythm TRY PRO FREE FOR 7 DAYS Every new account gets all of Pro for its first week, with no payment and no card needed. After that, keep it with a monthly or yearly subscription, or carry on free. DON'T TAKE OUR WORD FOR IT Log how you feel for a week. Your journal shows how closely your real energy tracked the maths. Your call after that. HONEST BY DESIGN Biorhythms are a lens for reflection, not science or medical advice. RhythmBio suggests; it never tells you what will happen.
