Why pH

A small number that says a lot.

Vaginal pH is a simple, low-cost signal you can check at home in about a minute. On its own it's just a number — but tracked over time, alongside how you feel and where you are in your cycle, it becomes context you and your clinician can actually use.

Lylac turns scattered readings into a clear, private picture of what's normal for you.

CYCLE-AWARE

Readings are viewed in the context of your cycle day, so normal fluctuations aren't mistaken for problems.

SYMPTOMS IN CONTEXT

Pair each reading with how you feel physically and emotionally — the full picture, not a single number.
