Slide Deck
App Design Walkthrough
Today, we'll explore the key features of budgeting apps and learn how to design our own Budget Buddy app!
Welcome to the App Design Walkthrough! Today, we'll learn about budgeting app features and brainstorm your own app concepts. Encourage engagement and questions.
Why Budgeting Apps?
- Visualize your money flow
- Make informed spending decisions
- Set and track financial goals
- Get real-time feedback
Explain why budgeting apps are helpful. Ask students to share if they have seen or used a money-tracking tool or app.
Feature: Income & Expense Tracking
- Record money you earn (income)
- Log money you spend (expenses)
- See balances in real time
Discuss income vs. expense tracking. Provide examples such as allowance as income and buying snacks as expenses.
Feature: Categories & Budgets
- Group expenses into categories (e.g., Food, Fun, Savings)
- Set spending limits for each category
- Compare actual spending to your budget
Talk about categories. Ask for examples of spending categories students use at home.
Feature: Alerts & Goals
- Get notifications when you approach budget limits
- Create saving goals (e.g., new game)
- Track progress toward your goals
Explain alerts and goal setting. Provide example of saving for a toy or game.
Design Tips: Keep It Simple
- Use clear labels and icons
- Maintain a clean layout
- Use consistent colors and fonts
- Make navigation intuitive
Share design principles. Encourage simple design and consistent visuals.
Brainstorming Your App
- List must-have features (e.g., tracking, alerts)
- Sketch the main screens (home, transaction, settings)
- Think about user steps and flow
- Use notes to explain your sketches
Guide students through the brainstorming process. Explain each step before they begin.
Next Steps
- Form your design teams
- Grab chart paper and markers
- Start sketching your app screens

Discussion
Needs vs. Wants Chat
Objective
Help students distinguish between “needs” (necessary items and services) and “wants” (nice-to-have items), laying the foundation for thoughtful budgeting.
Group Setup
• Divide into teams of 3–4 students.
• Assign one student as Recorder to capture ideas, one as Speaker to share with the class, and others as Contributors.
Instructions
- Spend 5 minutes defining needs and wants in your own words.
- Spend 10 minutes discussing the prompts below.
- Recorder writes key ideas and examples.
- Speaker shares one example of a need and one example of a want with the whole class.
Discussion Prompts
-
What is a Need?
• Describe something you must have to live or go to school.
• Why is it important?Your Definition & Example:
-
What is a Want?
• Describe something fun or nice to have but not required.
• How might it make life more enjoyable?Your Definition & Example:
- Sort the Items
Below is a mixed list. In your group, copy each item into the correct column.
| Needs | Wants |
|---|---|
| _____ Backpack | _____ Video game |
| _____ Lunch | _____ Designer shoes |
| _____ Textbooks | _____ Candy |

Real-Life Scenario
Imagine you have $10 allowance for the week. You need a bus pass ($4) and a healthy snack ($2). You want a comic book ($5).
• What will you choose to spend on?
• How much money will you have left?
• Would you save any? Why or why not?Your Plan & Reasoning:
Follow-Up Questions
• How do needs and wants affect your budget choices?
• If you had more money, how might your thinking change?
• How can identifying needs first help you reach a saving goal (like in our app design)?
After the chat, use your group’s ideas to inform your team’s budgeting app design in the Budget Buddy Project Guide. Good luck, Budget Buddies!
