Check both hardware requirements
ConsoleTuner requires the Titan Two Bluetooth Module and a microSD card for Gtuner Air. Verify both are present in the Titan Two. A phone with Bluetooth or a controller that already connects wirelessly does not establish that the Titan Two has the module and storage required by the app.
The manufacturer lists iOS and Android versions separately. Use its links to the appropriate app store and check the current store listing for your phone. The device requirements and the phone requirements are independent. A phone can support the app even if the Titan Two itself is missing an accessory.
Choose mobile configuration or desktop development
Gtuner Air is useful for browsing published work, configuring supported Gamepacks, and making adjustments away from a desktop. For writing and compiling GPC2 code, inspecting input versus output in Device Monitor, or editing a macro timeline, use Gtuner IV on a computer. Keep the saved source and any notes about the active slot with your desktop project.
The official desktop changelog also records a Device Configuration option to enable or disable Gtuner Air connectivity. If you can program over USB but the phone cannot see the device, check that setting and the required accessories before changing your console’s output mode.
Verify a change after programming
Use a spare slot for the first mobile configuration. Select that slot on the Titan Two and check one behavior you deliberately changed. If it behaves like your old setup, confirm the active slot and the installed work before modifying another setting. This keeps pairing, programming and runtime behavior separate.
