Hi In terms of using Quickbooks online, when im carry my phone, is there any apps for this or I have to use my Google Chrome?

Yes, QuickBooks has a mobile app available for iOS and Android, Daniel. Also, you can access QBO using Google Chrome or other supported browsers. Let me share more information about it.

To address the slow performance you're experiencing, I suggest regularly checking for updates and installing them as they become available. This can help ensure that you have access to the latest features and performance improvements. Follow these steps to refresh your data and clear the app's cache:

For iOS:

1. Go to Settings, then tap General.
2. Tap iPhone Storage, then tap the QuickBooks Online app.
3. Tap Offload App.
4. This will free up the storage without deleting your app's documents and data. 

For Android:

1. Go to Menu ☰, then tap More Options ⋮.
2. Tap Settings, then Refresh Data.
3. Tap YES to confirm.

If this doesn't work, proceed by uninstalling and reinstalling the app from your phone to resolve this issue.

Finally, I'd like to share this article to better manage your menu on the QBO app and how you can customise it to meet your workflows efficiently: Understand the navigation menu in QuickBooks Online.
