Marker.io is great for websites. ClientLens is that experience for mobile apps.
If you love the Marker.io workflow — clients report visually, tickets land in Jira — but your project is a native iOS, Android, React Native, or Flutter app, this is the tool you were searching for.
Start Free TrialSame philosophy. Different platform.
Marker.io earned its place in web agencies for a simple reason: it lets clients report issues visually, right where they see them, without creating accounts or learning a bug tracker — and every report reaches the dev team with full technical context.
But Marker.io is a website feedback tool. Its widget runs in the browser. The moment your client project is a native mobile app, there is no widget to embed — and you are back to WhatsApp screenshots and "it doesn't work on my phone" emails.
ClientLens applies the same philosophy inside the app itself. Native SDKs for iOS, Android, React Native, and Flutter let clients shake the device, annotate a real screenshot, record a voice note, and submit — while the SDK captures the device model, OS version, screen name, and logs automatically. The report lands in Jira, Linear, or GitHub, exactly like you are used to.

What ClientLens brings to your mobile builds
Everything you like about visual web feedback, rebuilt for the app store era.
Built where your app actually runs
A browser extension or web widget cannot see inside a native app. ClientLens SDKs live inside the app itself — capturing the real screen, the device model, OS version, screen name, and logs at the exact moment your client spots the issue.
The same client-friendly experience, on a phone
What makes Marker.io great for agency websites — clients report without accounts or training — is exactly what ClientLens does for mobile. Clients shake the device or tap a button, draw on a screenshot, add a voice note, done.
AI triage and fixes, not just tickets
Every report is auto-classified as a bug, feature request, or improvement, with priority scoring and duplicate detection. On Pro and Agency plans, AI analyzes your codebase and opens a draft pull request with a suggested fix.
Reports land in the tools you already use
Just like Marker.io on the web, ClientLens pipes mobile reports into Jira, Linear, ClickUp, Trello, Asana, Monday, Notion, GitHub, GitLab, Bitbucket, Slack, Teams, or any webhook — with screenshots and device context attached.
When Marker.io is the better choice
This one is easy, because the two tools barely overlap. Choose Marker.io if:
- The project is a website or web app — Marker.io's browser widget, web screenshots, and console/network capture are purpose-built for that and genuinely excellent.
- Your clients review staging sites on desktop browsers, not app builds on physical devices.
- You have zero mobile projects on your roadmap.
Choose ClientLens for every project that ships to the App Store or Google Play. And if your agency does both web and mobile? Run both — they can feed the same Jira or Linear backlog, so your team never notices the difference.
Marker.io for mobile: common questions
What agencies ask when their feedback workflow needs to cover mobile apps.
Marker.io is built for websites and web apps — its widget runs in the browser, so it cannot capture feedback inside native iOS or Android apps. For native mobile apps (including React Native and Flutter), you need an in-app SDK like ClientLens, which captures the real app screen, device model, OS version, and logs from inside the app.
ClientLens is the closest equivalent to Marker.io for native mobile apps. It delivers the same agency-friendly workflow — clients report visually without accounts, reports flow into Jira, Linear, or GitHub — but through native SDKs for iOS, Android, React Native, and Flutter, with shake-to-report, voice notes, and automatic crash capture.
Yes, and many agencies should. If you build both websites and mobile apps for clients, Marker.io covers the web projects and ClientLens covers the mobile ones. Both can feed the same Jira or Linear workspace, so your team works from one backlog regardless of platform.
They shake the device or tap a floating button. The SDK captures a screenshot, they draw on it to highlight the problem (with arrows, shapes, text, or a blur tool for sensitive data), optionally record a voice note, and submit. No account, no training, no separate app. Device context is attached automatically.
Marker.io team plans start at roughly $49/month. ClientLens plans start at $4.99/week ($17.99/month) for Starter, with Pro at $15.99/week and Agency at $36.99/week. Every ClientLens plan starts with a free trial — no credit card required — and includes a 14-day money-back guarantee.
When the project is a website or web app. Marker.io is excellent at browser-based feedback — pixel-accurate web screenshots, console and network logs, environment data — and it is a mature, well-loved tool for web agencies. ClientLens does not do website widgets; it exists to bring that same experience to native mobile apps.
