    Due to its newer and less widely adopted nature, there might be limited third-party libraries and plugins readily available compared to more mature frameworks.

Questions & Answers

As answered by people managing Runnify and Nullstack.

Which are the primary technologies used for building your product?

Runnify's answer

Flutter (iOS & Android), REST APIs, and smartwatch APIs (Garmin, Coros, etc.).

What makes your product unique?

Runnify's answer

Runnify combines science-based running coaching with the flexibility of modern technology. Instead of offering generic plans, every training program is tailored to the runner’s current fitness level, goal, available training days, and progress.

Every workout includes guided warm-up, the main session, and cool-down routines, while strength, mobility, and running technique sessions are integrated into the training plan. Runnify also syncs with leading sports watches, making it easy to follow structured workouts wherever you train.

Who are some of the biggest customers of your product?

Runnify's answer

We’re currently focused on individual runners rather than enterprise customers.

Thousands of runners use Runnify to prepare for races ranging from their first 5K to the marathon. Our community includes beginners, recreational runners, and athletes looking to improve their personal bests under the guidance of Olympian coach Daniel Andújar.

Why should a person choose your product over its competitors?

Runnify's answer

Most running apps either generate plans automatically or offer static training schedules.

Runnify is different because it focuses on personalized progression designed by experienced running coaches. Whether you’re preparing for your first 5K or trying to set a new marathon personal best, your plan adapts to your goal and fitness level instead of forcing you into a one-size-fits-all schedule.

Unlike many competitors, Runnify also includes strength training, mobility, running drills, guided warm-ups, cool-downs, progress tracking, and structured workouts that can be sent directly to compatible sports watches.

How would you describe the primary audience of your product?

Runnify's answer

Runnify is designed for recreational runners of all abilities.

Our users range from complete beginners training for their first 5K to experienced runners preparing for 10K, half marathon, or marathon races and aiming to improve their personal bests.

It’s ideal for runners who want expert guidance without hiring a personal coach.

What's the story behind your product?

Runnify's answer

Runnify was created by runners who believed personalized coaching should be accessible to everyone.

The project was developed together with Olympian and professional running coach Daniel Andújar, combining years of coaching experience with modern technology. Our mission is simple: help every runner train smarter, avoid injuries, and enjoy consistent progress, regardless of experience or performance level.
