Qlc or Tlc

QlcOrTlc reads storage controller fields from a complete system diagnostic archive that you import through the iOS document picker.

The app supports Simplified Chinese, Traditional Chinese and English. Requires iOS 26.6 or later. Reports are evaluated by their storage evidence, without a device-model whitelist. Compatible archive and record formats with the required fields are needed; support for every device or OS version is not guaranteed.

Follow the in-app guide to obtain a diagnostic archive, use the sysdiagnose search hint to find it, and import the complete file. View TLC / QLC evidence, keep the latest eligible result, share a text summary, or delete the local result.

A definitive type requires agreement between the NAND name and bits-per-cell fields. Single-field evidence is labeled accordingly. Missing or conflicting evidence is not replaced with a guess based on speed, capacity, or vendor.

A complete sysdiagnose gzip/tar archive is required. Ordinary .ips logs and screenshots are not sufficient. The current compressed-file limit is 1 GiB.

The app does not directly scan the phone's chip or prove that a report belongs to the current device. Results are not Apple certification, authenticity checks, health scores, or lifespan estimates.

No account, diagnostic upload, advertising, or third-party analytics. Analysis runs on the device. You retain control of the original archive.
