MiCTS
Triggers Circle to Search on Android 9–16 devices.

About MiCTS
MiCTS is an Android app whose main job is to open Circle to Search on phones running Android 9 through 16. It acts as a trigger only. The project says it does not handle problems that come up after Circle to Search opens. Setup can take some work, because several options depend on the Android version, the phone brand, and LSPosed module settings.
Pricing is not clearly stated.
