How to Create Drinking Water Reminder App

Creating a drinking water reminder app using MIT App Inventor involves designing the app’s user interface and programming the logic to send reminders. Here’s a step-by-step guide to help you create this app:

There Some following Steps for Designing

1. Setup and Create a New Project

1. Go to the MIT App Inventor website.
2. Click on “Create Apps!” and log in with your Google account.
3. Start a new project by clicking “Start new project” and name it something like “WaterReminder”.

2. Design the User Interface (UI)

1. Screen1:

   • Title: Set to “Welcome Water Reminder”.
   • Layout: Use VerticalArrangement for better organization.

1. Components:

• • Labels: Add labels to guide the user.
    • Label1: Set the text to “Welcome to Drinking Water Reminder”.
    • Label2: Instructions or info about the app.
  • Buttons: Add buttons for starting and stopping the reminder.
    • Button1: Set the text to “Start Reminder”.
    • Button2: Set the text to “Stop Reminder”.
  • TimePicker: To set the interval for reminders.
    • TimePicker1: Default interval setter.
  • Clock: Used to trigger reminders.
    • Clock1: Set TimerEnabled to false initially.
    • Set Time Interval: for Example 1 Sec = 1000
  • Sound : To play a sound with reminders.
    • Sound1: Upload a suitable sound file.

Block Coding 

Switch to the Blocks tab to add the logic.

1. Start and Stop Reminder:

• Button1.Click: Start the reminder..
  • Drag and Drop a Block <when Button1.Click> from Button1 Section
  • Drag and Drop a Block <set Clock1.TimerEnabled> from Clock1 Section
  • Add a Logic True and False Block from Logic Section and set it True to Start Counter
  • Attach all Blocks as Below….

2. Initialize the Clock Timer:

• When the app starts, set the clock interval using Clock1.Timer to a default value (e.g., 3600000 for 1 hour).
• Drag a Block <when Clock1.Timer> from Clock1 Section for activating sound alarm
• Take Another Bock <call Sound1.Play> from Sound1  Section
• Attach both Blocks like this…..

• Button2.Click: Stop the reminder.
  • Duplicate the whole Block of Button1.Click
  • Change the condition of <set Clock1.TimerEnabled> from True to False to STOP the Reminder sound.
  • Take Another Bock <call Sound1.Stop> from Sound1  Section
  • Attach all Blocks Like This……

Here is the Complete Block Code 

There are Some Steps to Generating APK File 

• Finish Project: Ensure all features are working and any bugs are fixed.
• Build APK: Click on the “Build” button in the MIT App Inventor interface and select “App (save .apk to my computer).”

• Download APK: This will compile your app and prompt you to download the APK file to your Phone.
• Direct Installation

1. Transfer APK: Move the APK file to your Android device using a USB cable, email, or cloud storage.
2. Allow Unknown Sources: Enable installation from unknown sources in your device’s settings.
   • Settings → Security → Install unknown apps → Select the file source (browser, file manager) and allow.
