⚡ Real-Time Sync via Google Firebase (Free)
Follow these steps once. After setup, this app works on any phone or computer — all data syncs instantly across your whole team.
Open console.firebase.google.com in a browser → click "Create a project" → name it mapano-budget → skip Google Analytics → click Create.
In your new project: left menu → Build → Realtime Database → click "Create database" → choose Singapore (asia-southeast1) → select "Start in test mode" → Enable.
After creating the database, go to the Rules tab and make sure it looks like this, then click Publish:
{
"rules": {
".read": true,
".write": true
}
}
If this says false instead of true, the app cannot save any data — that is why adding members or releasing funds does not work.
Click the ⚙️ gear (Project Settings) → scroll to "Your apps" → click the </> (Web) icon → name it BudgetApp → Register. Copy the entire firebaseConfig = { ... } block shown.
Open this file BudgetMonitor_Mapano.html in Notepad (right-click → Open with → Notepad). Find the section that says PASTE YOUR FIREBASE CONFIG HERE near the top of the <script> block. Replace the placeholder values with your real values.
In the same area, change const OWNER_PIN = "1234" to your preferred secret 4-digit number. Save the file.
Upload the file to Google Drive, share the link with your staff. They tap the link, open it in any browser — no app to install. Or share via Viber/Messenger as a file attachment.
Until Firebase is configured, the app runs in Demo Mode — everything works but data is stored on your device only (not shared with staff).
