Floating Bubble App Android — Always-On AI on Your Screen

Looking for a Floating Bubble App for Android?

You’re not alone. The search for a floating bubble app for Android usually starts the same way: you’re tired of switching between apps to do simple things. Copy a code from messages, check a translation, draft a reply — every task means leaving what you’re doing, opening another app, and finding your way back.

A floating bubble on Android solves this by putting a tool right on top of whatever you’re doing. No app switching. No lost context. Just tap the bubble, get what you need, and keep going.

But most floating bubble apps for Android are limited. They handle one thing — a calculator, a notes widget, a chat head. What if your floating bubble android app could summarize articles, extract OTPs and meeting links, draft replies, create flashcards, and chat with AI about what’s on your screen?

That’s Arc.

What Is a Floating Bubble App?

A floating bubble app is any Android app that displays a small, tappable circle (or panel) on top of your current screen. You tap it to expand a tool or window, then collapse it when you’re done. The bubble stays visible across app switches, so you always have quick access.

Android has supported this pattern since the Bubbles API in Android 10, and android 17 bubbles expand it further. But the OS-level bubbles are notification-triggered and limited to apps that implement the API. A floating bubble app for Android — a third-party tool like Arc — works independently: it’s always there, always available, and not tied to any specific notification.

Most people searching for a “floating bubble app” actually want something more versatile than a single bubble. Arc offers a floating sidebar — a thin edge panel you swipe to open. It works like a floating bubble (always on top, available in any app) but gives you access to a full suite of AI tools instead of just one feature:

Floating bubble: Small circle, single action (e.g., calculator, note)
Floating sidebar: Edge panel, multiple AI tools (summary, extract, write, chat, flashcards)

Think of the sidebar as a floating bubble that graduated from single-purpose to multi-purpose.

Arc: The Floating Bubble App for Android That Does More

Arc AI Screen Assistant is a floating bubble app for Android that lives on the edge of your screen as a persistent sidebar. Swipe to open it, and you get instant access to AI-powered tools that work on whatever you’re looking at:

AI Summary

Reading a long article or email? Tap AI Summary and Arc condenses it into key points — right over your current app. No switching to a separate summarizer. No copy-pasting. The summary floats on top, you read it, you close it, you continue.

Smart Extract

The real superpower. Tap Smart Extract and Arc scans your screen for actionable items:

OTP / verification codes — surfaced first with one-tap copy (auto-clears from clipboard in 2 minutes)
Meeting & video call links — Zoom, Google Meet, Teams
Events & dates — add to calendar directly
Contacts — names, phone numbers, emails with one-tap save
Addresses — open in Maps
Phone numbers — direct dial

Each extracted item gets a tappable action button. This is what makes Arc different from any other floating bubble android app — it doesn’t just float on your screen, it reads it and acts on it.

AI Writer

Draft replies, rewrite text, fix grammar, or create posts — right in the input field of any app. Works in WhatsApp, Gmail, Slack, Instagram DMs, or anywhere you type. The floating sidebar gives you four writing modes with tone and length options.

AI Chat

Ask follow-up questions about what’s on your screen. Arc uses your current screen content as context, so the conversation is relevant to what you’re actually doing.

Flashcards

Turn any screen content into study flashcards with one tap. Swipe through them in the built-in viewer. Great for studying from textbooks, notes, or web articles — all triggered from the floating bubble on your screen.

How Arc’s Floating Bubble Works on Android

Install Arc from the Google Play Store
Grant permissions — Accessibility Service (to read screen content) and overlay (to display on top of other apps)
A floating bar appears on the edge of your screen — this is your bubble
Swipe inward to expand the sidebar and see all AI tools
Tap any tool — Summary, Extract, Writer, Chat, Flashcards
Collapse when done — the bar stays on the edge, ready for next time

The entire interaction takes seconds. Swipe, tap, act. No opening a separate app, no navigating menus, no losing your place.

Floating Bubble App: Why Arc Beats Single-Purpose Bubbles

There are plenty of floating bubble apps for Android in the Play Store. Most fall into these categories:

Type	What It Does	Limitation
Chat heads (Messenger, WhatsApp)	Floating message bubbles	Only for that app’s messages
Floating calculator	Quick math on top of any app	Just a calculator
Floating notes	Quick note-taking overlay	Just notes, no AI
Floating browser	Mini browser in a window	Tiny viewport, limited
Arc floating sidebar	AI summary, extract, write, chat, flashcards, call insights	None — works across every app

The problem with single-purpose floating bubble apps is exactly that: they’re single-purpose. You install five different bubbles for five different tasks, and your screen becomes cluttered with circles.

Arc consolidates everything into one floating sidebar android experience. One swipe, one panel, every tool you need.

Real-World Use Cases for a Floating Bubble on Android

1. Copy an OTP Without Switching Apps

You’re logging into your bank. The verification code arrives as an SMS. Instead of switching to messages, memorizing the code, and switching back:

Swipe to open Arc’s floating sidebar
Tap Smart Extract
The OTP appears first — tap “Copy Code”
Paste it. The clipboard auto-clears in 2 minutes.

Total time: 3 seconds. Zero app switches.

2. Summarize a Long Article While Reading It

You’re in Chrome reading a 3,000-word article. You want the key points but don’t have time for the whole thing:

Swipe to open Arc
Tap AI Summary
Read the condensed version floating over the article
Close the sidebar and continue reading where you left off

3. Draft a Reply in WhatsApp

Someone sends you a long message in WhatsApp. You want to reply thoughtfully but don’t want to type a wall of text:

Swipe to open Arc
Tap AI Writer → Reply mode
Arc generates a polished reply based on the conversation
Tap to insert it into the chat field

4. Add a Meeting from an Email

A colleague emails you a meeting invite with date, time, and Zoom link:

Swipe to open Arc
Tap Smart Extract
The date gets “Add to Calendar,” the Zoom link gets “Join Meeting”
One tap each — done

Customizing Your Floating Bubble on Android

Arc’s floating sidebar is fully customizable:

Position: Left or right edge — pick what feels natural for your hand
Trigger size: Small, medium, or large edge handle
Auto-collapse timing: How quickly the sidebar hides after you’re done (instant to 5 seconds)
Per-app settings: Show Arc in some apps, hide it in others (e.g., hide in banking apps)
Custom AI actions: Create your own prompts for tasks you do repeatedly
Community actions: Browse 250 community-created actions in 10 languages

Device Integration

Arc’s floating sidebar also works with your phone’s built-in sidebars:

Samsung Edge Panel — add Arc as a shortcut
OnePlus Shelf — quick access from the OnePlus sidebar
OPPO Smart Sidebar — integrated with OPPO’s native panel

If your phone has a native sidebar, Arc works with it. If it doesn’t, Arc is your sidebar.

Privacy: Your Floating Bubble, Your Data

A floating bubble app for Android has broad screen access, so privacy matters. Arc’s approach:

Screen content is processed on-demand only — Arc reads your screen when you tap a tool, not passively in the background
Extracted items are ephemeral — nothing is stored on remote servers after you close the results
OTP clipboard auto-clears after 2 minutes for security
Per-app controls — block Arc from sensitive apps like banking
Optional region selection — extract only part of the screen, not everything

The floating sidebar sees your screen only when you ask it to, acts only on what you select, and forgets immediately.

FAQ: Floating Bubble App for Android

What is the best floating bubble app for Android?

Is a floating bubble app different from Android’s native bubbles?

Yes. Android’s native bubbles (including Android 17 bubbles) are notification-triggered and limited to apps that implement the Bubbles API. A floating bubble app like Arc works independently — it’s always available, not tied to notifications, and offers AI-powered tools. See our guide to Android 17 bubbles and floating windows for how the OS feature works.

Arc is designed for battery efficiency. The auto-collapse feature means the sidebar only draws power when actively in use. You can adjust collapse timing and per-app visibility to minimize impact.

Yes. They serve different purposes. Use native bubbles for quick message notifications. Use Arc’s floating sidebar for AI-powered multitasking — summaries, extraction, writing, and custom actions.
