Glyppo: GLP-1 & Weight Tracker

Your GLP-1 sidekick to track doses, log symptoms, and see progress with simple visuals, clear insights, and at-a-glance home screen widgets.

Inspiration

I love health-tech and wellness apps. As a person living with diabetes for over a decade, I’ve seen first-hand how the right tools can make day-to-day management easier and more empowering. Building apps like MIRA and Glu Sight showed me how thoughtful design can help people build habits and stay consistent with their health routines.

With the rapid rise of GLP-1 medications like Ozempic, Wegovy, and Mounjaro, millions of people are beginning treatment journeys and looking for support. Yet the apps that exist today often feel overwhelming. They try to do too much, put too many choices in front of users, and bury the core needs under layers of configuration.

I built Glyppo to fill that gap. It focuses on the essentials: doses, symptoms, weight, and progress. Nothing more, nothing less. The goal is to make tracking effortless so users can focus on their health, not the hassle.

What it does

Glyppo is a GLP-1 companion app designed to make treatment tracking simple and effective. It helps people using medications like Ozempic®, Wegovy®, Mounjaro®, Zepbound®, generics, and compounds stay on top of their journey without feeling overwhelmed.

With Glyppo, users can:

  • Log doses in seconds with a one-tap flow that supports editing and corrections
  • Track symptoms with severity and notes to spot patterns and side effects over time
  • Monitor weight changes with history, charts, and Apple Health sync
  • Use home screen widgets for countdowns, reminders, and at-a-glance progress
  • Stay on schedule with reminders that adjust for timezones, daylight savings, snoozing.
  • Export clean CSV reports (30, 60, 90 days) to share with care teams

Privacy and simplicity are built in. Sensitive data can be hidden from the App Switcher, and users only see what matters: doses, symptoms, weight, and progress.

How I built it

I built Glyppo entirely in SwiftUI for iOS 26 and above. Data is stored locally with SwiftData, with weight readings synced through Apple HealthKit when users grant permission. I implemented all permission requests using progressive disclosure so users are not overwhelmed with multiple prompts at the start. Permissions only appear when the feature is relevant.

The design makes extensive use of the new Liquid Glass system in iOS 26, which provides clarity and depth across the interface while keeping the focus on content. Accessibility has been a priority from the start, with full support for dynamic type, voiceover, and high contrast in future releases.

At the time I started building Glyppo, the iOS developer community was actively debating whether MVVM still made sense in SwiftUI. Since I already had extensive experience with MVVM, I decided to take the simpler MV approach and see how it would affect the project. The result was a leaner architecture that kept the app small and manageable while still allowing clean ways to test it. For an app like Glyppo, MV proved to be the right choice. It reduced overhead, avoided unnecessary architectural complexity, and let me focus on building features quickly. At the same time, the structure was designed so the app could still scale and support new features without issues.

RevenueCat powers subscriptions and paywall management. I integrated the RevenueCat Purchases SDK to handle entitlements, free trials, and renewals without manual server logic. Paywalls and offerings are managed remotely so pricing and copy can be adjusted without requiring an app release.

I used Xcode 26 for development and testing, along with AI assistants such as the built-in Xcode tool, AlexSideBar, and Cursor. Widgets were built using WidgetKit to provide quick access to dose countdowns, reminders, and fast logging for symptoms and weight progress directly from the home screen.

Challenges I ran into

A key challenge was balancing simplicity with completeness. Many existing GLP-1 apps overwhelm users with configuration and options. I needed to design an interface that was approachable for first-time users but still reliable for long-term tracking.

Another challenge was structuring subscriptions and entitlements in RevenueCat in a way that felt clear and non-intrusive. I also had to test different paywall flows to make sure the experience was consistent with Apple’s guidelines and user expectations.

Working with iOS 26 introduced additional challenges. Several new APIs, including those related to the Liquid Glass system, had little documentation at the time. I had to ensure that what I was building would continue to function properly in the final release of the operating system.

Beyond technical work, I also had to evaluate whether Glyppo was worth building beyond my personal passion for building wellness apps. GLP-1 is a relatively niche but fast-growing market. There are not many competitors, and worldwide GLP-1 treatments are often paid out of pocket rather than through insurance. That means many people who use GLP-1 for lifestyle purposes have the means to afford a subscription, provided the app delivers real value.

Accomplishments that I’m proud of

I first developed MIRA for the Shipaton. While it was a strong technical achievement, I realized after release that I had stepped into both an oversaturated market (journaling apps) and a niche one (video-first journaling) at the same time and it would take much longer to surface the value of the app.

That experience helped me pivot quickly and move up the timeline for Glyppo, which had originally been planned for later in the year.

What I’m most proud of is the execution: staying focused on the features that mattered, avoiding scope creep, and delivering a product that solved a clear need. I took Glyppo from idea breakdown to App Store release in just three weeks, compared to the three to four months it usually takes me to build an app I feel confident releasing.

What I learned

From my earlier apps MIRA and Glu Sight, I learned the importance of App Store Optimization (ASO). For Glyppo, I focused on metadata strategy from day one, using tools like Astro and App Store search prompts to identify opportunities and refine positioning. This helped ensure the app could reach the right audience and stand out in a market that is still emerging but highly competitive.

I also learned how important it is to think about monetization early. Using RevenueCat, I was able to structure subscriptions in a way that kept the experience clear for users while giving me flexibility to iterate on pricing and offerings.

I learned the value of community. Seeing so many builders share their challenges and approaches has been inspiring. I learned from their experiences, and whenever possible, I contributed advice of my own. That exchange reinforced the importance of collaboration, even in indie development.

Finally, I learned the value of focusing on pure execution. Instead of building feature after feature, I kept the scope small and delivered only what mattered. That clarity made it possible to go from idea to App Store release in three weeks without sacrificing quality.

What’s next for Glyppo: GLP-1 & Weight Tracker

The next phase for Glyppo is to expand thoughtfully, guided by data, user feedback, and a focus on simplicity.

On the product and business side, I plan to:

  • Integrate TelemetryDeck for richer insights into where users drop off, what features they engage with, and what pain points need to be solved.
  • Continuously improve visibility on the App Store through ASO refinements, Product Page Optimization, and other marketing initiatives.
  • Experiment with paywalls and subscription flows to increase LTV while keeping the experience fair and transparent,
  • Add RevenueCat’s Customer Center when the app gains more traction, to give users greater control over their subscriptions.

From a technical perspective, I plan to:

  • Explore Apple’s on-device intelligence when it can enhance usability in a meaningful way.
  • Respond to user feedback and prioritize features that both drive conversions and maintain Glyppo’s simplicity.
  • Research competitors to stay informed, while staying true to the goal of avoiding unnecessary complexity.

Above all, Glyppo will continue to grow with focus. Every new feature or experiment will be measured against the core principle of delivering clarity and value to people on GLP-1 treatments. The long-term vision is to make Glyppo the most trusted, accessible, and supportive companion app for this growing community worldwide.
