The TestApp.io Mobile App: Install Builds, Test Tasks, and Share Feedback from Your Phone

Omar Masad -

When you distribute a mobile build to testers, the experience should not stop at a download link. Testers need a way to install builds, see what they are supposed to test, report what they find, and switch between versions — without leaving their phone.

The TestApp.io mobile app does exactly that. It turns every tester's device into a complete testing workstation. Here is how it works.

One-Tap Installation

Most build distribution tools give testers a link. They tap it, a file downloads, and they figure out the rest. On Android that means hunting for the APK in their downloads folder. On iOS it means navigating provisioning profiles and trust settings.

The TestApp.io app eliminates that friction. When a new build is uploaded, testers receive a push notification. Tapping it opens the release directly. On Android, a single tap starts the download and walks through installation automatically. On iOS, the app provides a QR code or direct link that handles the provisioning flow.

After installation, the button switches from "Install" to "Open" — testers can launch the build without leaving the TestApp.io app. If a newer build comes along, the button changes to "Upgrade" so testers always know when they are behind.

Tasks on the Device

Telling testers "go test the app" without specific guidance leads to shallow, unstructured feedback. That is why the TestApp.io app surfaces tasks directly on the tester's phone.

Each app has a Tasks tab showing what needs to be tested. Tasks include status (new, in progress, blocked, done), priority, assignee, and a link to the specific release they apply to. Testers can update task status as they work — marking items in progress, flagging blockers, or completing them — all without switching to a browser.

If your team uses Jira or Linear, tasks sync bidirectionally. A tester marking a task as "blocked" in the app updates the linked Jira or Linear ticket automatically.

Feedback with Attachments

The best bug reports include context. The TestApp.io app lets testers submit feedback with up to 10 attachments — screenshots, screen recordings, or any other images and videos captured on their device.

Every release has a Comments tab where testers write feedback and attach files. Attachments upload in the background, so there is no waiting around. The same comments appear in the portal for developers and PMs who are triaging issues from their desk.

This matters because testers are on the device where the bug lives. They can capture exactly what they see — a glitchy animation, a layout issue on their specific screen size, a crash on their OS version — and attach it to their report in seconds.

Version History and Rollback

One of the most common questions during QA is: "Was this bug in the last version too?" With the TestApp.io app, testers can answer that themselves.

The Releases tab shows every build ever uploaded for an app, with platform and status filters. Testers can install any previous version, reproduce the issue, then install the current build to confirm the fix. No need to ask a developer to dig up an old build and re-share it.

This is especially valuable for regression testing — when you ship a fix, your testers can verify it did not break something that was working before by comparing the old and new builds side by side.

Real-Time Everything

The app does not rely on polling. Real-time updates push changes to every connected device immediately:

  • A new release is uploaded — testers see it in their release list and get a push notification.
  • A task is assigned or updated — the task list reflects the change instantly.
  • A comment attachment finishes processing — the thumbnail appears without refreshing.
  • A release changes status (active, archived) — the UI updates in place.

This means testers always see the current state of the project. No refreshing, no wondering if they are looking at stale data.

Multi-Team Support

Testers who work across multiple projects can switch between teams from the side menu. Each team has its own set of apps, releases, tasks, and notifications. The switch is instant — all data refreshes to show the selected team's workspace.

If a tester receives a deep link or push notification from a different team than the one they currently have open, the app automatically switches context to the right team.

Getting Started

The TestApp.io app is available on iOS and Android. Testers sign in with their existing TestApp.io account (email, Google, or Apple sign-in) and accept a team invitation to start seeing releases.
