Bloom is a responsive web app, so the same app.bloom.study that you use on a laptop also works on your phone or tablet. There is no separate iOS or Android app to install. Open the URL in your mobile browser, sign in, and the layout adapts to your screen size with touch-friendly controls. Every feature available on desktop (chat, documents, canvas, quizzes, voice input) is available on mobile, just rearranged to fit a smaller screen.
This guide walks through what changes on mobile, how to switch between the Chat and Workspace views, and how to add Bloom to your home screen so it opens like a native app.
Before you start
You need:
- A phone or tablet with a modern browser. Chrome, Safari, Firefox, and Edge all work. Use the latest version for the best experience.
- An existing Bloom account. If you do not have one yet, sign up at app.bloom.study on any device.
- A working internet connection. Bloom uses streaming responses, so a stable connection helps.
Step 1: Open Bloom on your phone
Open your mobile browser and go to app.bloom.study. Sign in with the same email or institutional SSO you use on desktop. Your Blooms, conversations, quizzes, and uploaded documents are all the same account, so anything you started on a laptop will be waiting for you on mobile.
Step 2: Navigate the mobile layout
Bloom switches to its mobile layout at screen widths of 1023 pixels or below, which covers all phones and most tablets in portrait orientation. The desktop sidebar collapses behind a menu button, and the side-by-side Chat + Workspace view becomes a pair of top-level tabs you can switch between.
The mobile-specific changes you will notice:
- Sidebar: tap the menu button (top-left) to open it. Tap outside or pick a destination to close it. This is where you switch between Blooms, open conversation history, and reach Settings.
- Top-level tabs: when a Bloom has Workspace features available (documents, canvas, quizzes, Desmos), you will see Chat and Workspace tabs at the top. Pick one at a time, since both panels cannot fit side by side on a phone.
- Documents: the page-aware document viewer still works, you just view the document in the Workspace tab and switch back to Chat to ask about it. Bloom remembers which page you were looking at when you switch tabs.
Step 3: Use chat features on mobile
The chat composer works the same way it does on desktop, with one space-saving change: at screen widths of 430 pixels or below, the Deep Think and Guided toggles collapse into a single options button. Tap the slider icon next to the message field to open a popover where you can switch them on or off.
Other things to know:
- Voice input: tap the microphone icon in the chat input to dictate your question. Your browser will ask for microphone permission the first time. If you see a “No microphone device was found” message, check that your phone has microphone access enabled for the browser in system settings.
- Streaming responses: Bloom streams replies token by token, the same as on desktop. Keep the tab in the foreground while a response is streaming, since some mobile browsers throttle background tabs.
- Attachments: tap the attachment icon to upload an image or document from your phone (camera roll, Files, or cloud drives). Long-press the input area to paste an image you copied from another app.
- Equations and code: render correctly on mobile. For long code blocks, swipe horizontally inside the block to scroll without scrolling the whole conversation.
Step 4: Add Bloom to your home screen
Adding Bloom to your home screen turns it into a one-tap shortcut that opens in standalone mode (no browser address bar or tab strip). It looks and feels like a native app.
iOS (Safari)
- Open app.bloom.study in Safari.
- Tap the Share button (the square with an upward arrow) at the bottom of the screen.
- Scroll down and tap Add to Home Screen.
- Confirm the name (“Bloom” by default) and tap Add.
Android (Chrome)
- Open app.bloom.study in Chrome.
- Tap the three-dot menu in the top-right corner.
- Tap Add to Home screen (or Install app if Chrome offers it).
- Confirm and tap Add or Install.
The Bloom icon now appears on your home screen with the same honeydew-yellow logo you see in the app. Tapping it opens Bloom directly, skipping the browser entirely.
Common issues
The sidebar will not close after I pick something
Tap anywhere outside the sidebar (on the dimmed overlay) to close it manually. If the overlay is unresponsive, refresh the page. This is usually a one-off render issue.
I cannot see the Workspace tab
The Workspace tab only appears when the current Bloom has Workspace features enabled (documents, canvas, quizzes, or Desmos). On a brand-new Bloom with no documents and no canvas content, you will only see the chat. Upload a document or open the canvas, and the tab will appear.
Voice input does nothing when I tap the mic
Your browser likely needs microphone permission. On iOS, go to Settings > Safari > Microphone and allow access for app.bloom.study. On Android, tap the lock icon in the address bar and toggle Microphone on. Reload the page after granting permission.
Streaming responses pause or cut off
Mobile browsers can throttle background tabs and inactive screens to save battery. Keep the Bloom tab in the foreground while a response is streaming. If it stalls, scroll up to confirm the message did not already complete, then send a quick “Continue” if it really stopped.
The page looks broken or layouts overlap
Update your browser to the latest version. Bloom supports the current and previous major version of Chrome, Firefox, Safari, and Edge. Older builds of Safari in particular can render newer CSS incorrectly.
