THE DAILY CHALLENGE

Real Effort. Honest Care.

Your movement directly nourishes your pet. Every step and active workout converts into transparent Care Points with zero artificial inflation.

👟 1 STEP = 1 CP

Measured Steps

Synced directly from Apple Health or Android Health Connect. Pure walking and running steps feed your pet stride for stride.

⚡ 1 KCAL = 20 CP

Eligible Workouts

Cycling, rowing, swimming, and HIIT contribute active calories. Walking workouts never double-count step points.

🟢 DAILY GOAL

The Care Ring

Close your ring before midnight. Finalizing your daily care goal advances your companion's survival ledger toward Day 40.

🌿 NO GUILT

Streak Protection

Sick or traveling? Gentle Mode pauses streaks kindly. Pets never perish, and survival days are never erased.

The little reason people keep moving.

From an evening walk around the block to keeping a 40-day lion thriving, see how a virtual companion makes everyday movement genuinely rewarding.

I used to forget about my evening walk. Now I check on my cat and end up going around the block.

Emily R.
Sample

My lion just hit 40 days, and now the challenge is getting real. I thought I was doing great before. Lol.

Marcus T.
Sample

I love my little virtual pet. It gives my steps a reason beyond watching a number go up.

Sarah M.
Sample

The first time my dog looked happy after a walk, I got it. This is a surprisingly fun way to stay active.

Daniel K.
Sample

My routine was getting boring. Having a pet to care for made the same walk feel different.

Olivia P.
Sample

My friends and I keep checking whose pet is doing best. It’s a friendly push to get outside.

Jason B.
Sample

I’m a little hooked on checking my pet’s progress. I’ve started taking the stairs just to give it a boost.

Nicole A.
Sample

The lion is no joke. I picked it for the challenge, and it definitely makes me think twice about skipping a walk.

Andrew C.
Sample

It feels good to see my activity turn into something my pet needs. I look forward to opening the app.

Rachel S.
Sample

I never cared much about a step counter. I do care about keeping my shark going.

Kevin L.
Sample

My sister and I started together. Seeing her pet climb the leaderboard gets me moving every time.

Jessica W.
Sample

Some days all I do is take a longer walk after dinner. Seeing that count still feels rewarding.

Brian H.
Sample

I chose the llama because it made me laugh. Now I’m invested in seeing it grow up.

Amanda F.
Sample

The daily goal is simple to understand, and the pet makes it a lot more fun than another fitness chart.

Tyler N.
Sample

I like that I can see how close my pet is to its goal without digging through a bunch of screens.

Megan D.
Sample

I started with a cat and kept going because I wanted to see the adult version. The growth is a great touch.

Chris J.
Sample

My friends tease me about checking on my deer. Then they ask how to get one.

Lauren V.
Sample

It turned my lunch break into walking time. I still get my break; my pet gets its care.

Eric P.
Sample

I wasn’t looking for a serious training app. This gave me a small challenge I actually enjoy coming back to.

Hannah G.
Sample

One of my clients had trouble getting started between sessions. I suggested she try the pet challenge. She began walking more often, and we’ve had something positive to build on together.
