What's Inside
KruNest isn't another solo tracker — it's a full accountability ecosystem built around the people who keep you going.
Create or join a private Kru with your friends, family, or teammates. Small groups, real accountability — no strangers, no noise.
Set shared fitness goals, track weekly progress per member, and compete on the leaderboard. Kru Momentum keeps you on track.
Rate your discipline across 4 levels every day. Build self-awareness and spot the patterns that power lasting habits.
Test yourself across Strength, Endurance, Flexibility, and Stability. Your radar chart evolves as you improve over time.
Log any workout manually or auto-sync with Apple Health. Full history organised by date, type and intensity.
Real-time group chat, emoji reactions, and a Nudge button to encourage members who've gone quiet. Because accountability needs a human touch.
Every week, KruNest writes your story. An AI-generated summary of your workouts, Pulse score, streak, and Kru highlights — so you see exactly how far you've come.
See your Kru's workouts roll in live. React with emojis, celebrate wins, and never miss a moment when someone in your circle crushes a session.
How It Works
Use KruNest on the web instantly (open beta, free) or request iOS or Android early access. No card required.
Start a private Kru and invite your Kru via a simple code or link. Your Kru, your rules.
Launch a group challenge, set the duration and targets, and watch the Kru Momentum build.
Log workouts, check your Daily Pulse, Nudge your Kru, and celebrate every milestone.
Our Mission
You've downloaded the solo tracker. You've set the streak goals. You've watched the motivational reels at 6am.
And then life happened.
The truth is, consistency isn't a personal failing — it's a design problem. Most fitness apps are built for individual willpower. But human beings don't work that way. We show up for each other.
KruNest is built around small, private groups — your Kru — where real accountability lives. Your Kru sets challenges together, logs workouts together, and checks in on each other every single day.
Because when someone in your Kru logs a 6am run, you feel it. When you miss a day, they notice. That's not pressure — that's the good kind of accountability that moves the needle.
"The secret to showing up? People who notice when you don't."
