SmartBP is a heart-health app where users log blood pressure, pulse, weight, and more — with BMI, pulse pressure, and MAP calculated automatically. Users can tag entries with context (like “before dinner” or “left arm”) and sync seamlessly with Apple HealthKit. Despite these features, many users downloaded the app but didn’t engage daily.
As a UX designer, I focused on two goals: gamify logging to build daily habits and create an intuitive medication reminder system — all while keeping within brand constraints and without offering tangible rewards.
User research and analytics revealed a clear problem: many SmartBP users downloaded the app but stopped logging after a few days. Logging felt like a chore with no immediate payoff, and users often forgot readings or medications. Competitive analysis showed top health apps used gamification or reminders to boost engagement, but most relied on tangible rewards we couldn’t offer.
With the team, I sketched out a core idea: a 7-day streak challenge. Users who log their blood pressure every day for a week would earn a reward: one week of free premium access (unlocking advanced charts and statistics). The length (7 days) was chosen as a manageable habit cycle.
We made these design choices:
Streak Tracker UI: On the home dashboard, a prominent “Streak” banner showed days logged vs. goal. Each day you logged became a lit-up icon. Missing a day broke the chain.
Reward Tease: We designed a congratulatory screen for completing a streak.
Motivational Messaging: We added subtle motivational text (“You’re on a 3-day streak!”) and occasional push reminders (“Don’t break your streak – log your BP tonight!”).
Balanced Tone: Serious health tracking meant no cartoon graphics; brand blue-green theme guided colors with subtle accents for streaks.

The Pill Problem and Our Approach
Parallel to the BP log upgrade, I tackled medication adherence. Interviews confirmed that users often “forgot pills” or found existing reminder apps cumbersome. Envisioned SmartBP as a one-stop health companion, so I designed a medication module to schedule, remind, and log medicines easily.
Ideation
With the medication tracker, users can quickly add medicines, schedule doses, and rely on timely push reminders to stay on track. The log and adherence dashboard provide clarity on habits, and premium insights link medication adherence to blood pressure trends.
