Health tracking app development

We build health tracking apps with IoT and connected device integration— so you can offer smarter insights, achieve better user engagement, and get stronger results.

Who is this for?

  • Healthcare providers
  • Fitness and lifestyle startups
  • Wearable tech companies

What your custom health tracking app can include

Activity and fitness tracking

Capture detailed movement data like steps, workouts, heart rate, and calories burned. Whether connecting to wearables or using native device sensors, your app can give users accurate, real-time insights into their fitness progress.

Nutrition and hydration logging

Make it simple for users to track what they eat and drink. We can build custom food databases, barcode scanners, and smart tracking systems that encourage healthier eating habits without feeling like a chore.

Sleep monitoring

Help users understand how well they’re sleeping—and how to improve it. We enable sleep tracking modules that measure sleep cycles, quality, and duration, paired with visual feedback and personalized improvement tips.

Chronic condition management

Support users managing ongoing health issues with custom modules for tracking symptoms, medication schedules, blood pressure, glucose levels, and more. These features help users stay engaged with their care routines and simplify provider communication.

Personalized goal setting

Give users a way to set health milestones and track their journey. From daily step counts to long-term wellness targets, we build flexible goal frameworks that adjust to user behavior and celebrate progress along the way.

Data visualization and insights

Raw data alone isn’t enough. We create clear, user-friendly dashboards and visual reports that turn health information into meaningful insights, helping users make smarter decisions about their health every day.

Multi-platform accessibility

Users expect access across all their devices. We design systems that perform smoothly across iOS, Android, web, and wearables, creating a truly connected health experience no matter where your users are.

Great, but why DECODE?

Here’s why you should hire us to develop your custom health tracking app:


One team, one client

When we work with you, you’re not just another name in the queue. You’ll have a dedicated, cross-functional team focused entirely on your project. That means fewer handovers, faster decisions, and a team that knows your product inside and out.

We understand connected health

Health tracking isn’t like building a to-do app. It involves wearables, IoT, secure APIs, structured health data, and real-time syncing. We’ve built and integrated with these systems before. You won’t have to educate us on HL7, Bluetooth pairing, or HIPAA.

Total transparency

We work in the open. You’ll always know what’s happening, what it costs, and why we’re making certain decisions. From day one, we set up clear communication and shared tools, so there are no surprises—just progress.

What you can expect

  • Higher user engagement with actionable health insights
  • Better retention rates by building features that grow with users’ needs
  • Access to real health data that unlocks smarter insights, services, and strategies
  • Improved user health outcomes through smarter tracking, reminders, and feedback loops

NEXT STEPS

Before we start our partnership, we have to make sure
we’re a right fit for you.

Over a relaxed call or two, we’d like to hear as much as possible about your project
(fully NDA’d of course).

We’ll talk about:

  • Your expectations
  • Services you need
  • Your vision

There are a few steps in this phase:

  • We’ll hand-pick a team based on your desired seniority level and other requirements.
  • We’ll send you their CVs so you’ll know every engineer working for you.
  • If necessary, we can set up interviews between you and every engineer.

Only when you’re 100% on board with our choice, we’ll go to the next phase.

If everything sounds good to you, we’re ready to get started.

This could be the start of a
great partnership
