Introduction: Why Choose AppSheet?

Before we begin, let's understand why AppSheet is worth learning.

Three Core Advantages

1. No Coding Required

Traditional App development requires learning Swift, Kotlin, or at least JavaScript.

AppSheet doesn't.

If you can use Excel or Google Sheets, you can make an App.

2. Google Ecosystem Integration

AppSheet is a Google product.

It seamlessly integrates with Google Sheets, Google Drive, and Gmail.

If your company uses Google Workspace, adoption has virtually zero barriers.

3. Super Fast Development Speed

Traditional App development: 3-6 months.

AppSheet: Hours to days.

This isn't an exaggeration—it's true.

Your First App: Task List

We're going to make a simple task list App.

Features include:

• Add tasks
• Mark completion status
• Set due dates
• Assign owners

Step 1: Prepare Data Table

First, create data in Google Sheets.

1. Open Google Sheets

Go to sheets.google.com and create a new blank spreadsheet.

2. Name the File

Name the file "Task List"

3. Create Fields

Enter the following field names in the first row:

A	B	C	D	E
TaskID	TaskName	Status	DueDate	Owner

Important Notes:

• Use English for field names to avoid issues
• Each field name must be unique
• First column should ideally be an ID

4. Add Sample Data

Starting from the second row, enter some test data:

TaskID	TaskName	Status	DueDate	Owner
T001	Complete Weekly Report	To Do	2025-12-20	John
T002	Reply to Customer Emails	In Progress	2025-12-18	Sarah
T003	Prepare Meeting Slides	Completed	2025-12-15	John

The data table is now ready.

Step 2: Connect Data

Now connect Google Sheets to AppSheet.

1. Return to AppSheet

Open the AppSheet console (appsheet.com)

2. Create New App

Click "Create" → "App" → "Start with your own data"

3. Name the App

Enter an App name, e.g., "My Task List"

4. Select Data Source

Select "Google Sheets"

Find the "Task List" file you just created

Select the worksheet (usually Sheet1)

5. Wait for Auto-Generation

AppSheet will automatically analyze your data structure.

After a few seconds, your first App is generated!

It's still basic, but it already works.

---

Step 3: Set Field Types

AppSheet will automatically guess field types, but usually needs adjustment.

1. Go to Data Settings

Click "Data" → "Columns" in the left menu

2. Adjust Field Types

Field	Recommended Type	Description
TaskID	Text	Unique identifier, set as Key
TaskName	Text	Task name
Status	Enum	Dropdown: To Do/In Progress/Completed
DueDate	Date	Date picker
Owner	Text	Person responsible

3. Set Enum Options

Click the Status field, and in "Type Details" set options:

• To Do
• In Progress
• Completed

This way users can select status from a dropdown instead of typing manually.

4. Set Display Names

Each field can have a "Display Name" set:

Field	Display Name
TaskID	Task ID
TaskName	Task Name
Status	Status
DueDate	Due Date
Owner	Owner

This way the App interface displays friendly names.

---

Step 4: Set Up Views

Views determine how data is presented.

1. Go to UX Settings

Click "UX" → "Views" in the left menu

2. Set Up Main List View

Find the system-created View (usually called "Task List")

Adjust these settings:

• View type: Table or Deck (cards)
• Sort by: DueDate (sort by due date)
• Group by: Status (group by status)

3. Create Calendar View

Click "New View" to add a view:

• View name: Calendar
• View type: Calendar
• Start date: DueDate

Now you have a calendar view.

4. Adjust Card Display

If using Deck View, you can set:

• Primary header: TaskName
• Secondary header: Owner
• Summary column: Status

Step 5: Create Forms

Forms let users add and edit data.

1. Check Form Settings

AppSheet automatically creates forms.

Find "Task List_Form" in "UX" → "Views"

2. Adjust Field Order

Put the most important fields at the top:

1. TaskName (Task Name)
2. Status
3. DueDate (Due Date)
4. Owner
5. TaskID (can be set to auto-generate)

3. Set Default Values

In "Data" → "Columns", you can set default values for fields:

Field	Default Value
Status	To Do
DueDate	TODAY() + 7 (seven days later)
TaskID	UNIQUEID()

This way when adding a task, status is automatically "To Do" and due date is automatically one week later.

4. Set Validation Rules

Ensure data quality:

• TaskName: Required
• DueDate: Valid If = [_THIS] >= TODAY() (cannot select past dates)

---

Step 6: Test the App

Before publishing, you must test.

1. Use Live Preview

The right side of the AppSheet editor has a live preview.

Click "Preview" to simulate the phone screen.

2. Test Basic Functions

• Add a new task
• Edit an existing task
• Change task status
• Check the calendar view

3. Phone Testing

Download the AppSheet App (iOS/Android)

Log in with the same Google account

Your App will appear in the list

4. Check Syncing

Add data in the App and check if Google Sheets updates synchronously.

It should be instant.

---

Step 7: Publish and Share

Once testing is complete, you can publish.

1. Click Deploy

Click "Manage" → "Deploy" in the left menu

2. Run Deployment Check

AppSheet will run automatic checks to ensure no serious issues.

If there are errors, it will show prompts. Fix them and try again.

3. Set Sharing Permissions

In "Users" set who can use it:

• Domain users: Same company Google Workspace users
• Allowed users: Specified Email list
• Public: Anyone (requires paid plan)

4. Send Invitations

Enter team members' Emails and send invitations.

They'll receive an Email and can click the link to use the App.

Congratulations! Your first App is complete.

Advanced Tips

Now that you've learned the basics, let's learn some advanced tips.

Conditional Formatting

Make different statuses show different colors.

1. Set Status Colors

In "UX" → "Format Rules" add rules:

Rule 1: Completed shows green

• Condition: [Status] = "Completed"
• Icon: Green checkmark
• Highlight color: Light green

Rule 2: Overdue shows red

• Condition: AND([Status] <> "Completed", [DueDate] < TODAY())
• Icon: Red warning
• Highlight color: Light red

Rule 3: In Progress shows yellow

• Condition: [Status] = "In Progress"
• Icon: Yellow dot
• Highlight color: Light yellow

This makes task status visible at a glance.

Automated Notifications

Let the App send reminders automatically.

Note: Automation features require Starter plan or above. For detailed plan comparison, see AppSheet Pricing Complete Guide.

Set up deadline reminders:

1. Go to "Automation" → "Bots"
2. Create a new Bot
3. Set Event:
   • Event type: Schedule
   • Schedule: Every day at 9 AM
4. Set Process:
   • Find tasks due tomorrow that aren't completed
5. Set Task:
   • Send Email to Owner

This way every morning, owners receive reminders for tasks due the next day.
