The platform
From device to proof
in three steps.
One repeatable workflow replaces subjective manual checks — so every device leaves your bench with the same standard of evidence.
Connect
Plug in over USB or pair wirelessly. Diagify auto-detects the model, OS, serial, and IMEI in seconds — no manual lookup, no spreadsheets.
- Auto-detect model & identifiers
- Batch up to 40+ at once
- Mac & Windows desktop apps
Diagnose
60+ guided and automated tests run across battery, display, cameras, sensors, audio, and connectivity — then a real-time IMEI and blacklist check.
- Hardware + software coverage
- GSMA & carrier verification
- Consistent, operator-proof results
Certify
Diagify grades the device against your rules and mints a signed, tamper-proof certificate with a QR code linked to the live record.
- Branded PDF reports
- SHA-256 signed & auditable
- QR-linked device history
Capabilities
Everything you need to
ship a device with proof.
Real-time IMEI & blacklist verification
Every diagnostic queries the GSMA registry and carrier sources by IMEI — catching stolen, financed, or carrier-locked units before they enter your inventory.
Signed certificates
Tamper-proof, SHA-256 signed PDFs a buyer or auditor can verify — operator, timestamp, and method included.
Batch testing
Connect and process 40+ devices in parallel. Diagify standardizes every test, grade, and report across the whole lane.
Secure data erasure
NIST 800-88 Clear & Purge wipes with a legally defensible certificate for every device — ADISA and GDPR aligned.
A fleet dashboard & API that automate everything
One cloud workspace for every device, report, and teammate. Stream diagnostics, grades, certificates, and erasure events into ecommerce, inventory, ERP, and analytics — on schedules or webhooks.
Why it matters
“A grade label without a diagnostic report is just an opinion — and opinions lead to disputes.”
A signed certificate travels with the device and answers the question every buyer eventually asks: can I trust this? That trust turns inventory into revenue — and cuts the cost of returns, write-offs, and chargebacks.

“We cut returns by a third in our first quarter. Buyers trust a Diagify certificate because they can actually scan it and verify it themselves.”
Marcus Lim
Operations Lead, ReNewed Mobile · Singapore
“Intake used to be our bottleneck. Now one operator certifies 200 devices a day — and every single grade is defensible if a customer pushes back.”
Priya Anand
Refurb Floor Manager, CellCircular · Manchester, UK
“The IMEI and blacklist check alone paid for the platform. We stopped buying stolen and financed units almost overnight.”

FAQ
Questions, answered.
How long does a full diagnostic take?
Most devices go from intake to a signed certificate in under three minutes. Diagify auto-detects the model and runs 60+ tests in parallel, so there's no manual checklist slowing operators down.
Can I test multiple devices at once?
Yes. Batch testing lets operators connect and process 40+ devices in parallel using the macOS and Windows desktop apps. Diagify standardizes every test, grade, and report across the whole lane.
What exactly is an IMEI check?
An IMEI check verifies a device's unique identifier against global blacklist databases — confirming whether it's reported stolen, financed, or carrier-locked. Diagify queries the GSMA registry and carrier sources in real time as part of every diagnostic.
Which devices does Diagify support?
1,000+ models — every iPhone, iPad, Mac, Apple Watch, and AirPods, plus Samsung Galaxy (S, A, Note, Z Fold, Z Flip), third-party Android, Windows laptops, wearables, and robotics fleets.
Are the certificates legally defensible?
Every certificate is SHA-256 signed and tamper-proof, recording the operator, timestamp, method, and result. Secure erasure follows NIST 800-88 Clear and Purge patterns and is aligned to ADISA and GDPR standards.
Does it work on both Mac and Windows?
Yes. Diagify ships native macOS and Windows desktop apps for diagnostics, plus a centralized cloud dashboard for managing devices, reports, and team members from anywhere.
