Deeplink Checker is a deep link testing tool for iPhone and iPad. It tells you whether a custom URL scheme or Universal Link opened your app, not just that it was tapped: build a test, run it, and get a straight verdict for every link.

Put your app scheme, universal link and paths into one test. In a hurry? Test straight from your clipboard, or scan a QR code and see what is behind it before you open it.
A guided run walks through the test one link at a time, so you can watch what each one does and record what happened, with an optional screenshot per step.
Every link, its verdict, the device and the app version on one report card. Share it as text or an image, or export CSV and PDF.
Built for iOS developers, QA engineers and anyone who ships deep links and has to prove they work.
Every link gets a real verdict: opened in the app, fell through to Safari, or nothing claimed it. Universal links are opened the way iOS opens them, so you see what your users see.
Walk a test step by step, then share or export the result as a report card. Runs are kept, so you can compare this release with the last one and see what broke.
Fetch and validate your apple-app-site-association file the way iOS does, see the Team ID and Bundle ID it claims, and keep every check in a searchable history you can diff.
When a link still will not open, one tap diagnoses the file, its rules, your app's identity and Apple's CDN copy, then ranks the likely causes with fixes.
See what is behind a code before you open it, and turn any link into a styled code with a label and colours, exported as PNG, SVG or PDF.
Run a saved test from the Home Screen, save a link from any app through the share sheet, or wire a check into a Shortcut.
Tests, runs, reports, AASA checks and QR codes are stored in your own iCloud and follow you to every device you are signed in to. No account to create.
Group tests, links, domains and reports into a workspace per app, run a whole workspace as one session, and brand every exported report.
Everything the first version did is still free, and so is sync. Pro adds the professional workflow.

The three things that decide whether a tap lands in your app, and what Deeplink Checker does with each.
A scheme such as myapp:// is claimed by whichever installed app registers it. Deeplink Checker opens the link and reports whether any app claimed it, so you catch a missing scheme or a typo in CFBundleURLSchemes before your users do.
An https:// link opens your app only if iOS has verified your domain and a rule in the AASA file matches the path. The tester opens each link with Universal Links only, so "opened in app" means iOS really did hand the link to an app, while "fell through to Safari" means it did not.
The AASA file at /.well-known/apple-app-site-association maps your Team ID and Bundle ID to the paths your app handles. The AASA checker fetches it the way iOS does, validates the JSON, shows the rules, and keeps every check so you can diff what changed between releases.
Install Deeplink Checker, enter your app's custom URL scheme, Universal Link and paths in the Test Builder, and run the test. Each link is opened the way iOS opens it and gets a verdict: opened in the app, fell through to Safari, or nothing claimed it. Save the test and re-run it after every release.
Open the AASA Checker, enter your domain, and the app fetches the file from /.well-known/apple-app-site-association the way iOS does, validates the JSON, and lists the Team IDs, Bundle IDs and path rules it claims. Every check is kept in a searchable history, and Pro can compare the file with the copy on Apple's CDN.
iOS decides from the AASA file it downloaded for your domain when the app was installed or updated, not from what your server serves right now. Common causes are a file that is not served correctly, a path no rule matches, a Team ID or Bundle ID that does not match the build, or a device holding an old copy. The Link Troubleshooter checks each of these in one tap.
Yes. Testing custom schemes and Universal Links, guided runs, report cards, AASA validation, QR tools, widgets and iCloud sync are free. Pro adds the Link Troubleshooter, multi-path tests, workspaces, batch runs, CSV and PDF exports and unlimited history, as a subscription or a one-time purchase.
Yes. Deeplink Checker runs on iPhone and iPad with iOS 18 or later, including Split View and Stage Manager, and everything you save syncs between your devices through iCloud.
