How does Horiva track perimenopause symptoms differently from general period trackers?
General period trackers are built around a 28-day cycle model. Horiva's tracking logic is designed for the irregularity of perimenopause — cycles that skip, shorten, lengthen, or overlap with symptom clusters that don't map to a predictable schedule.
Can I use a symptom tracker to prepare for a doctor's appointment?
Yes. Symptom logs that cover multiple weeks or months give your doctor a much clearer picture than self-reported recollection. Horiva's symptom pages explain what data is most useful for different types of medical conversations — hormone testing, sleep evaluation, mental health screening.
Which perimenopause symptoms are hardest to track with existing apps?
Cognitive symptoms like brain fog and memory changes are poorly handled by apps designed for physical cycle data. Mood pattern tracking is also weak in most general trackers. The symptom pages document what each symptom requires for accurate tracking and whether existing apps support it.
