What it is

DiagnosticsTools is a local diagnostic analysis app for support, operations, and field troubleshooting. Import a ZIP diagnostic bundle on iPhone or iPad, browse its file tree, review summary overviews, and open structured viewers for each file type.

The current version focuses on local analysis: no sign-in required, and diagnostic bundles, log contents, or parsed results are never uploaded on their own.

Who it’s for

Support and operations teams inspecting diagnostic bundles on the go
Anyone handling iOS diagnostic logs who’d rather not send them to unknown servers
Field troubleshooters who match against a knowledge base to spot known issues fast

Why I built it

Getting a diagnostics bundle used to mean finding a computer, unzipping, and opening a pile of tools — far too heavy. DiagnosticsTools lets an iPhone or iPad do the whole job, with the data never leaving the device — great for quick mobile inspections, reproduction support, and on-site reading.
