Daily symptom tracking, with optional extras

DRSP, your own symptoms and interventions

Score 21 validated DRSP symptoms every day on a scale of 1–6: about 2 minutes. You can track more, but you don’t have to. Add up to 20 of your own symptoms (same 1–6 scale), grouped by area such as pain, sleep or skin. And up to 20 interventions: medication, supplements or other approaches such as exercise, sleep or diet, with dose or amount and frequency. Your own symptoms and interventions are not part of the DRSP total or the cyclic overview; they are there for your own picture and for your healthcare provider.

Tracker: filling in a new day with cycle mark and DRSP questions (1–6)
Tracker grid: DRSP symptoms per day in a colour-coded raster
Interventions: medication, supplements and other approaches, by type
Custom symptoms: extra symptoms besides DRSP

Heatmap, charts and cycle comparison

See patterns at a glance

A colour-coded heatmap, symptom course, category comparison, impact per phase and cycle comparison: all patterns in one place.

Cycle comparison: current cycle versus average DRSP per phase
Symptom course: DRSP total per cycle day with phase colours
Category comparison: average DRSP per category per phase
Impact on work, social life and relationships per cycle phase
Heatmap grid: symptom scores per day (colour codes 1–6)
Chart: pick up to three symptoms to compare

Structured pattern recognition

Cyclic overview

Based on the C-PASS method by Eisenlohr-Moul et al. (American Journal of Psychiatry, 2017). Makes cyclic patterns in your DRSP data visible. Per finished cycle, once enough days before and after menstruation are filled in.

Cyclic overview: cycle card with phase bar, scores and support days
Cyclic overview: cyclic domains, core symptom and functional impact
Cyclic overview: DSM-5 domains, pre- and postmenstrual phase compared
Cyclic overview: DRSP symptom details, averages and four criteria per symptom

Automatic phase detection

Cycle tracking

Follicular, ovulation, luteal and menstruation. Understand your cycle and how it lines up with symptoms.

Today: cycle ring, phase and daily check-in
Cycle calendar: month view with phase colours, menstruation and today marked
Timeline: days with phase, scores and notes
Profile: current cycle, streak and support days
Support: signals and actions for a support day
