Nila and your phone's health app
Your phone already counts. Nila is what happens after the counting.
Both iPhone and Android now do a decent job of collecting the basics — sleep, steps, resting heart rate, heart rate variability, cycle days — and newer iPhones will nudge you to see a doctor when your cycles have been irregular for a while. That is genuinely useful, and Nila doesn't try to replace it.
What your phone won't do is tell you what any of it means for a body in perimenopause, hand you the research behind an answer, write the letter for your appointment, or put you in a room with women a year ahead of you. That is the part Nila is for.
Side by side
Daily numbers
Your phone
Sleep, steps, resting heart rate, HRV and cycle days, collected from your phone and any wearable you own.
Nila
The same daily totals, brought in once a day and set beside the symptoms you logged that day.
Cycle irregularity
Your phone
Newer iPhones can notice a run of irregular cycles and suggest you talk to a doctor.
Nila
Takes that conversation further: what to ask, what the evidence says, and a doctor-ready letter you can hand over.
Symptoms
Your phone
A short list of logged symptoms, mostly cycle-shaped.
Nila
Menopause-shaped tracking — hot flashes, sleep, mood, joints, brain fog, libido — with an eight-week view.
Answers
Your phone
None. It shows the data and stops.
Nila
A graded research library and a chat that only answers from it, with the source shown.
People
Your phone
None.
Nila
A community of women in the same window, and a directory of menopause-trained practitioners.
Which phone
Your phone
Apple features are iPhone-only. Android has its own, different set.

The same Nila on both, so your history follows you if you switch.
The line we hold
No score, no grade, no verdict
Plenty of apps take the same numbers and turn them into a readiness score, a recovery percentage or a symptom grade. Nila doesn't. Your sleep hours arrive as sleep hours. If a number doesn't match how the night actually felt, trust how it felt — the number is an estimate from a sensor, and it is not a measure of how you are doing.
Where these numbers come from
These numbers come from your phone, watch or ring, not from a lab. Sleep hours and sleep stages in particular are estimates a device makes from movement and heart rate, and they can be some way off what a sleep study would find. Nila shows them back to you exactly as they arrived: no score, no grade, no reading of what they mean. If a number doesn't match how the night actually felt, trust how it felt.

Where this comes from
Apple and Google both publish what their health apps collect and how cycle tracking works. Nothing on this page is a claim about how accurate their estimates are.
