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.
Pick a goal — 1,500 squats in 30 days, 100k steps in two weeks. KruNest sets today's target based on what you've already logged. Built-in rest days keep streaks alive.
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.
Group Challenges
Pick an activity, a few minutes a day, a couple of days a week — for a few short weeks. Challenges layer on top of whatever you're already doing, not in place of it. Your Kru shows up with you, and one Momentum bar keeps everyone honest.
Strength & Endurance · 4 weeks
Week 3 of 4. Your Kru is on pace — 9 of 16 active days logged. A small daily rhythm with rest woven in, not piled at the end. Per-member weekly progress and one Kru Momentum bar for the whole group.
Built around your Kru. Challenges run inside a single Kru — leaderboards, weekly recaps, and the Nudge button keep everyone showing up, not just the keenest member.
Quests
Go for a number — 1,500 squats in 30 days, 100k steps in two weeks. KruNest sets today's target based on what you've already logged. Your Kru keeps you showing up.
1,000 Squats Quest
Day 1 you logged 50 squats. Today's target adapted to 52 — yesterday's 91 gave you breathing room. Calibrated to your Day 1 baseline, adapts when you crush or miss, with built-in rest days that don't break streaks.
3 Krus, same goal. Pick a quest in any Kru — the math, the rest days, and the streak come along for the ride. In multiple Krus? One log counts across all of them.

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."
