- Join Humbert, a Minotaur striving to regain his legendary fitness and reputation.

The fitness app landscape is full of titles that gamify exercise, from Marvel Move’s superhero-audio runs to The Conqueror’s virtual tours of Middle-earth. But only one begins with a grumpy Minotaur named Humbert, determined to rebuild both his public image and his glutes.
That app is Threkka, a unique twist on fitness that blends a tycoon simulator, a folklore-inspired dreamscape, and a habit-forming health tracker. It launched quietly on the App Store earlier this year and has been crafting an increasingly curious universe, one cardboard treadmill and GPS-challenged unicorn at a time.
In Threkka, your physical activity in the real world powers the revival of the Gym Between—a once-great wellness hub in the interdimensional realm of Liminalia. Whether you log a walk with Apple Watch or complete a Strava HIIT session, your effort generates Sweat, the game’s core resource.
Spend Sweat to level up your Champions, unlock new upgrades, and maintain the quirky inhabitants of Liminalia in peak condition. Every step and repetition creates a ripple effect across both worlds, connecting your fitness objectives to a far more engaging pursuit than daily streaks or progress charts.

Built on proprietary systems like “fitOS” and “Dragon Drop,” Threkka feels like a game first, not a tracker. It features simple one-finger controls, delightfully absurd shop menus, and a cast of lovingly designed characters who experience authentic recovery cycles and stat progression. Your Champions don't just gain levels; they need rest, manage fatigue, improve at specific exercises, and grow stronger over time—mirroring your own journey.

And if all that seems a little too wholesome, don't fret. You can still place an interdimensional PhaseTime call to the developers, feed your unicorn some GPS stabilizer, or ponder the narrative logic behind a confetti-powered treadmill.
