Alori: Irregular Period Cycle

Most period apps assume your cycle runs like clockwork. Alori is built for the rest of us.

If your periods are irregular, different every month, often late, or hard to predict, generic trackers can guess wrong and leave you anxious. Alori is different. It learns your actual rhythm and shows how confident it is in every prediction and why.

Predictions You Can Trust

Instead of giving you one date that may be wrong, Alori shows an honest prediction window, such as “Period likely Mar 12–16,” with a confidence score. It adapts to your real history instead of forcing your cycle into a 28-day template. When your cycle shifts, Alori re-anchors automatically.

Confidence Scores That Make Sense

See how sure Alori is about your next period and what is driving the prediction. For example: “Your cycles vary by about 5 days, and Alori adapts to that.” No false certainty. No silent guessing.

Know What Is Coming Before It Arrives

Alori helps you prepare with proactive forecasts, such as “PMS likely in about 3 days,” personalized from the symptoms you actually experience.
