Kort fortalt
Phasa: Period Tracker Calendar is a health and fitness app that predicts period start dates as a range with a confidence level, and can estimate fertile windows, phases, and pregnancy timelines. It suits people tracking cycles, trying to conceive, pregnant, or going through perimenopause. Logs stay on the iPhone with no account required, and it stands out for showing how many cycles back each pattern it finds is based on.
Resumé fra Debuts, baseret på app-siden i App Store.Om appen
Most period apps hand you one confident date. Bodies don't work that way. Phasa shows the days your period is likely to start, and that range tightens as it learns your rhythm — or stays wide, honestly, when your cycle is irregular.
HOW PHASA READS YOUR CYCLE • Looks at your recent cycles, sets aside the odd month out, and leans on the most recent ones • Shows a prediction window plus a confidence level that says what it's based on • Log basal body temperature and Phasa looks for the sustained rise after ovulation, then learns the length of your own luteal phase instead of assuming 14 days • Fertile window and phase for every day of your cycle
PATTERNS WITH THE EVIDENCE ATTACHED When Phasa spots something in your logs — headaches clustering before your period, low energy after short sleep — it tells you how many cycles that observation rests on. You decide how much it means.
LOG IN SECONDS Flow, symptoms, mood, energy, sleep, temperature, cervical mucus, notes and photos. A calendar that shows logged days, predicted periods and your fertile window at a glance.
MADE FOR DIFFERENT SEASONS OF LIFE Choose Period Tracking, Trying to Conceive, Pregnancy (week count, trimester and an estimated due date) or Perimenopause, where predictions widen to fit shifting and skipped cycles.
