- The vaginal ring is now available alongside the pill, IUDs, and the implant.
- Three new things to log - blood clots, smoking, and good sleep.
- Phase Patterns - see what you actually logged in the phase you're in, like "cramps in 4 of your last 5 luteal phases", with the number of cycles it's based on.
- Hormone Pattern - the four hormones drawn across your own cycle length, anchored to your ovulation instead of a generic day 14.
- Your energy on the chart - if you track energy, a dotted line shows your own logged levels across the cycle.
- We say when we're not sure - when your cycles vary too much to place a phase confidently, we tell you instead of guessing.
- Learn articles now show their evidence - sections labelled Well established, Mixed evidence, or Limited evidence.
