Stewi stands for stewardship.
We believe we’re all stewards of this incredible planet. Being a steward means caring for people and the Earth — and proving it through everyday actions.

Introducing Stewi

Stewi is a mobile app that helps you take small, positive actions for the planet — and see your progress grow over time.

Instead of just talking about sustainability, Stewi helps you do something about it. Small actions. Real impact.

Our goal is simple:
Help you and your family care for the Earth and its people — while saving money and building better habits. A true win-win.

🌿 Two Ways to Take Action

You can choose between two types of actions:

Make it a Habit

Repeat it over time (30 logs) until it becomes second nature.
Example: Take 5-minute showers.

Try Once

A one-time improvement.
Example: Switch to LED light bulbs.

Both types help you move forward — just in different ways.

🌎 Why It Matters

Each action can help you:

  • 💰 Save money

  • 📚 Learn something new

  • 🌱 Help the environment

  • ❤️ Improve your health

Many actions include built-in calculators so you can see how much money you're saving.

🌳 Watch Your Tree Grow

As you complete actions, your tree grows.

Tree growth is based on your overall progress:

  • 45% from Try Once completions

  • 55% from Habit progress

Your tree never goes backwards — we keep your highest progress.

⭐ Progress, Points & Levels

Stewi uses a friendly progression system:

  • Try Once completion = 15 points

  • Habit log = 1 point

  • Every 30 points unlocks 5 new actions

You also earn XP and levels to celebrate your consistency.
You never lose progress — this is about encouragement, not pressure.

📊 Simple Insights

The Insights tab shows helpful patterns like:

  • This week vs last week momentum

  • Your most consistent habits

  • Your recent wins

No spreadsheets. Just clarity.

🔒 Your Data Stays Yours

Your data is stored on your device.
We do not sell it. We do not share it.

Stewi is built to empower — not track you.
