Weights & Biases
Monitor training runs anywhere
Only for iPhone
Free · Designed for iPhone. Not verified for macOS.
Stay on top of your machine learning runs—without staying at your desk.
The Weights & Biases mobile app lets you monitor experiments in real time and get notified when something important happens.
Whether you’re training large language models, fine-tuning models, or running sweeps, you can:
• View live and completed runs
• Zoom and pan through training curves
• Track loss, accuracy, throughput, and custom metrics
• Receive notifications when runs finish or fail
• Get alerted when key metrics change
• Quickly sanity-check results between meetings
The app connects securely to your existing W&B projects so you can monitor progress from anywhere. No dashboards to rebuild—your runs are already there.
The W&B mobile app is available for Free, Academic, and cloud-hosted Enterprise (SaaS) accounts. Dedicated and on-premises deployments are not yet supported.
more Finally I can see my experiments on the go when I’m travelling, used to go to the mobile webpage all the time but having an app with notifications for failed experiments is superb.

Love the ability to see experiment results on the go, but I’d like to be able to group and tag runs similar to how the web version works.

iPhone Duo Support
- Introducing iPhone Duo support! Runs and panels appear side by side on the expanded display, and hiding or showing a run updates its charts immediately. ARIA shows a single new chat button and a sidebar toggle that looks and sits like one. Open any project on iPhone Duo to try it.
What’s New
- A redesigned metric chart detail view is cleaner and shows more information. It opens fullscreen from the metric card with a zoom transition, lists each line in a legend under the title, and uses evenly spaced axis ticks that stay in place when you zoom.
- Choose the x axis for a chart from the built-in axes or any numeric key your run logs, and search your keys with “Search X axis”.
- The app icon is blue instead of yellow, reflecting Weights & Biases as part of CoreWeave Forge.
Bug Fixes
- Runs tab loads faster for users who were seeing slow loading.
- Metrics keep loading as you scroll to the bottom of projects with many metrics, such as large_runs_demo.
- Run Overview shows your config parameters with their usual names, without SDK storage wrappers or internal metadata.
- ARIA chat history displays each thread’s title.
- Trigger lists load every page of triggers and show the correct starred state for each project.
- The line plot options sheet stays put when you pull down, instead of refreshing.
26.30 6d ago
What’s New
- Approve or deny ARIA requests for network access directly in a conversation, so tasks that need to reach a website, like downloading a dataset, can continue from your phone.
- Sheets look and behave more consistently, with system corner curvature, matching backgrounds, and a clearer close button.
- Profile, run overview, and notification settings pages keep a comfortable maximum width in landscape on larger devices.
Bug Fixes
- Splash screen text is legible in both light and dark mode.
26.29 Oct 12
What’s New
- ARIA saves your unsent draft, including run mentions, so it’s still there when you reopen ARIA.
- Tap blank space or response text in ARIA to dismiss the keyboard.
- ARIA conversations older than 30 days stay in your history, grouped by month.
- Push notification onboarding has a redesigned look.
Bug Fixes
- Mentioning runs and projects in ARIA works outside of a project context.
- Sampled image history includes the final logged step, and jumping to an exact step opens that step.
- Empty metric details keep the “No data available” message instead of showing a blank plot.
- The Runs list shows an empty state when a search returns no results.
- ARIA history titles show the mentioned run’s name instead of its internal ID.
- ARIA chat history and the composer omit the placeholder project name for conversations started without a project.
- Search fields keep the capitalization you type instead of capitalizing the first letter.
- VoiceOver announces changes in loading state.
- VoiceOver reads a correct label for the star button on individual run charts in the single-run view.
- The Runs charts section toggle has a VoiceOver label.
26.28 Oct 5
What’s New
- View image metrics from several runs at once on a project’s Panels tab. Page through each run’s image tile, scrub across steps with the slider, and switch samples with the sample picker when a run logs more than one image per step. Tap a run’s tile to open that run’s image metric detail view.
- Logged image captions appear on the image metric detail screen and in the fullscreen image viewer, with a tap to expand long captions into a scrollable panel.
Bug Fixes
- Fixed a visual glitch in the notification creation menu’s loading state.
- Chat history and the composer omit the internal default project placeholder name.
26.27 Sep 28
What’s New
- ARIA responses arrive faster, streaming in as they’re generated.
- Pin your favorite ARIA conversations to keep them at the top of the history list, regardless of new activity.
- Image cards for runs that are actively logging update with new steps automatically, without needing to pull to refresh.
- Viewing an image metric’s detail view after tapping it from a card, or scrolling a card in and out of view, no longer re-fetches data you’ve already loaded.
- Image metrics preserve your position and image counts as new data arrives, instead of resetting your scroll position or losing already-loaded images.
Bug Fixes
- The Runs tab reliably loads instead of occasionally getting stuck in a perpetual loading state.
- Runs in charts display in a consistent, stable order.
- Charts with a mix of logged images and videos show the metric’s supported image history instead of hiding the entire metric.
26.26 Sep 21
Ranged Bins on Charts
- Introducing ranged bins on your metric charts! When data is downsampled, a shaded band around the line shows the range of values hidden by aggregation, giving you a clearer sense of variance at a glance. Turn on the ranged bin tooltip in line plot settings to see the full range when you tap a point.
Bug Fixes
- VoiceOver improvements: the app’s name is pronounced correctly, run navigation headers and run charts announce a run’s state, and decorative icons like the search magnifying glass are no longer announced.
- Links within ARIA respond correctly to taps and open as expected.
- The ARIA chat list fills the screen correctly when you have no chats yet.
- Tapping the ARIA chat history button transitions to your chat history with a more natural animation.
26.25 Sep 14
Hide and Show Runs
- Introducing run visibility controls! Hide individual runs from the runs list to focus on the ones that matter, and your choices stay saved across the app. Look for the new control in any project’s runs list.
Bug Fixes
- Pan across a zoomed-in chart in the detailed plot view to see any part of the data.
- Tooltips on a zoomed-in chart display the correct data.
- Adjusting the smoothing slider no longer shifts the layout underneath your finger.
26.24 Sep 8
Image Metrics
Introducing Image Metrics! View images logged to your runs directly in the app, with smooth zooming and panning, a clean, distraction-free detail view, and a slider for scrubbing through images across multiple steps. Find it on any run page where you’d see metrics.
Chart Options
Introducing chart options for your metric line plots! Switch to a logarithmic Y-scale to compare metrics across orders of magnitude, and apply exponential moving average (EMA) smoothing that’s remembered the next time you open the app. Find chart options on any line plot.
26.23 Aug 31
What’s New
- Charts zoom and scale on both axes. Pinch vertically as well as horizontally, double-tap to zoom in a step at a time, and watch the Y axis rescale to the visible portion of the curve so small variations late in a run stay readable.
- Run cards on the Runs tab prefer a project’s starred metrics when choosing which metric to display.
- Viewing logs for a finished or crashed run stops polling for new lines, cutting network use and battery drain.
26.22 Aug 24
What's New
- Run cards on the Runs page prioritize your starred metrics when choosing which metric to display.
- The chart detail screen shows the metric name in the navigation title for a cleaner, more focused layout.
- The Runs tab omits the "Preview unavailable" message for runs that have no chartable metric, keeping run summaries focused on relevant details.

Bug Fixes
- The project menu button announces its purpose to VoiceOver users.
26.20 Aug 10
Enhanced Run Logs
Introducing an enhanced run logs viewer, rebuilt for large training runs. ANSI color output renders faithfully, so colored output from your scripts looks exactly as intended. Recent log output appears immediately even for runs with hundreds of thousands of lines, with the rest loading in the background. Find it in the Logs tab of any run.

Bug Fixes
- Sending a follow-up message in an agent conversation succeeds reliably, fixing an occasional failure.
26.17 Jul 20
ARIA gets a major upgrade with Agent Context: it automatically detects which project you're viewing in the app, so answers come with the right project already in mind. Open any project or run and start a conversation with ARIA to try it.
What’s New
- Agent chat keeps your sent message and ARIA’s response visible even if a background refresh happens while you’re waiting for a reply.
- Agent chat renders Markdown tables, so structured data in ARIA’s responses displays as an actual table instead of raw text.
- Agent chat renders more Markdown formatting, including headings, bulleted and numbered lists, inline code, and italics, making responses easier on the eyes.
- Tool calls in agent chat expand to show their arguments and output, with formatting for commands, diffs, and JSON. Errored and cancelled tool calls display their status, and clarifying questions render as a question prompt with selectable options.
Bug Fixes
- Text field placeholders display in the correct color.
26.16 Jul 13
What’s New
- Agent tool calls display their JSON with syntax highlighting, making arguments and output easier to read.
- A tool call that can’t be rendered shows a fallback card instead of interrupting the rest of the conversation.
- The agent’s message input has a refreshed look with a border and glass effect.
Bug Fixes
- The Overview tab opens smoothly while charts are still loading, without freezing the app.
- The Charts page loads correctly in some cases where it previously came up empty.

26.15 Jul 6
Introducing ARIA
- Introducing ARIA, the Weights & Biases AI agent, built right into the app. Chat with ARIA to ask questions and take action across your work, and follow along as it reasons through each step and calls tools to get things done. Tap the ARIA tab to start a conversation.
What‘s New
- Chat with ARIA in a conversational view built for mobile. Your messages appear in chat bubbles, replies render with full Markdown formatting, and ARIA keeps context across a multi-turn conversation.
- Follow along as ARIA works. See its reasoning as it thinks through a problem, and expand any tool call to inspect the arguments and output behind it, with code and JSON shown in formatted, copyable snippets and a live status while each step runs.
- Act on any reply. A message action bar beneath each completed response lets you copy ARIA‘s answer or send thumbs-up or thumbs-down feedback.
- Pick up where you left off. Browse past conversations from your chat history, sorted by most recent activity, and reopen any one to keep going.
- Stay in control. Start a new chat whenever you want, stop ARIA mid-response, and tap an example prompt to get started fast.
26.14 Jun 29
What‘s New
- Fixed an issue with diagnostic logging that will make it easier to track down bugs that cause missing runs and metrics.
26.13 Jun 15

- Metric cards with long names display the star button and chevron with correct alignment.
26.11 Jun 1
Live Refreshing
Live Refreshing expands throughout the app! Previously available only on single-metric detail charts, it keeps every chart up to date as new data arrives. The Runs tab and per-project runs lists also refresh on their own to show new runs as they start.
What's New
- Collapse the section of ungrouped metrics to focus on the named sections that matter to you.
- Scrolling past collapsed sections in a grouped runs list continues to load additional runs, so you can keep browsing without expanding every section.
Bug Fixes

- Follow a run‘s current status — like running, finished, or crashed — updating live in the header while you view the run.
- Monitor GPU utilization and other system metrics in runs to catch hangs or under-utilization during training.
- Toggle text wrapping on the logs tab to keep long log lines fully visible without horizontal scrolling.
Bug Fixes
