Dr. Greer’s relentless efforts towards the disclosure of classified UFO/ET information have inspired millions of supporters around the world. App features: - Official training materials developed by Dr. Greer - CE5 Guide, which provides an overview of all topics surrounding CE5 - CE5 Process, which walks users step-by-step through all aspects of initiating CE5 - Built-in networking functionality for finding and messaging others interested in CE5 - Comprehensive equipment list - Extensive library with video, images, audio samples, and meditations Notes: For active use of the app outdoors during CE5 work where connectivity may be limited, CE5 Contact includes offline mode for the CE5 Process section as well as local storage of previously visited pages or played/downloaded content.

Déjà Entendu ("Already heard" in French) allows iOS, iPadOS and macOS owners to dive into translate, transcribe and create flash cards from images, recordings or sound samples on their device. It is not a cloud service. So you can be assured that any use of the on-device content analysis that Apple Intelligence performs stays private to you. Import your class notes provided by teachers or translate mp3 files and audio clips that you've made or that you've purchased previously. New options for speeding or slowing pronunciation guides is introduced with the updated version along with options for direct speech input to the transcription tool. Social channels for extra How To instructions are accessible from the Home Tab. We hope you enjoy learning more of the languages that inspire you through our apps!
