Getting patients to show up every day
2026 · Pulse · Mobile Health App
Introduction
Pulse is a personal health app for logging symptoms, tracking patterns, and sharing reports with doctors. The core feature had a 78% drop-off rate after the first week. I joined for eight weeks to find out why and fix it.
The Problem
The logging flow asked 14 questions every day. Severity, sleep, mood, diet, hydration, activity, and more. It had been designed with clinicians in mind, not the people filling it out.
Most users opened the app once, saw the form, and never came back. The ones who stayed logged maybe twice a week, which made the pattern data clinically useless.
Solution
I cut the daily check-in to three questions with one tap answers. Users could add detail if they wanted, but the minimum viable log took under 20 seconds.
Introduced a streaks system and a weekly pattern summary so users could see their own data becoming meaningful over time.
Moved the full 14-question form to a monthly deep-dive, framed as something to do before a doctor's appointment rather than every morning.
Added a smart nudge that triggered only when the app detected a gap in logging, not on a fixed schedule.
Results
Weekly active logging went from 22% to 71% of registered users within six weeks. Average session length dropped from 4 minutes to 40 seconds, which was the goal. Doctors using the platform reported a 3x increase in patients arriving with complete weekly data.
