Your ChameleonUltra,
from your iPhone.
A native Bluetooth companion for the ChameleonUltra and Chameleon Lite — read, emulate, recover keys, and write cards, all controlled from your iPhone.
Coming to the App Store
Requires a ChameleonUltra or Chameleon Lite device.
Read & identify
HF (MIFARE Classic, Plus, Ultralight, NTAG) and LF (EM4x, T5577, HID, Indala) tags — UID, ATQA/SAK/ATS, NDEF, and full memory dumps.
Emulate cards
Load HF and LF cards into the Chameleon's eight slots and present them to real readers straight from the device.
Recover keys
Recover MIFARE Classic sector keys using the dictionary, nested, and reader-based recovery methods your device supports.
Write cards
Write to magic cards — Gen1a, Gen2/CUID, Gen3, Gen4/UMC, USCUID — and T5577 blanks. Write a UID only or a full dump, with an optional card-type override.
Manage the device
Slot manager, device settings, battery, capabilities, and over-the-air firmware updates (DFU) — no cable required.
Private by design
No account, no analytics, no backend. Cards, dumps, and recovered keys stay on your device and your Chameleon.
Chameleon GO is an independent companion app and is not affiliated with, endorsed by, or sponsored by RRG or Proxgrind. Use reading, emulation, key recovery, and writing only with cards and systems you own or are explicitly authorized to test.
