"PD Eyes" is an app to assist students and professionals with improving their presentation and interview skills. "Presentations are used by students and professionals in all fields of study and professional work. As you grow in your educational/professional field, you will need to acquire great presentation skills to deliver effective and engaging presentations to a variety of audiences. At this point, you have only done half the work, the research, the written speech, and the outlined notecards for your presentation and your instructors have told you to go and practice your presentation. NOW is the most important part, the part that scares most of us, the part that gets us to question our confidence and brings out the fears and anxieties that we don’t like to deal with. BUT you must PRACTICE to overcome these feelings and through this process, gain confidence in yourself and a belief that you can do this. It is said that more than 90% of people fear to speak in front of an audience. Whether it is a classroom presentation or a professional meeting presentation, a planned speech must be practiced more than one time. You don’t want to just read your speech and bore your audience. By using this app you will develop the discipline to keep your eyes up and make a visual connection with your audience. This will teach you to visually engage your audience to listen, learn and believe in what you have to share with them. Now let’s start building your confidence and overcome your feelings of anxiety and fear. As a speaker/presenter, in any life situation that you are in, is to keep your eyes on all of the audience members that you are speaking with. We are very rarely put in front of people to read to them. In this app, as you begin to practice your speech, you will be tested on this. When you begin your speech, different students at different intervals of time will raise their hands to see if you are keeping eye contact with your audience. If you are presenting your speech properly, you will see them raise their hand and make that connection. By tapping the student on the screen, you will get them to put their hand down. If your eyes are buried in your paper/notecards/speech because you are reading, you force an audience member with their hand up to get up and leave the room, vocally let you know of their disapproval. Your goal is to keep all your audience in their seats and get the loudest applause at the end." Never struggle with public speaking again...download PD Eyes today!

Verdict
The clearest difference is in-app purchases: Ozmotic Learning at none against PD's 3. Ozmotic Learning also leads on ads (none vs shown) and rating (5.0 vs 4.6). PD's advantage is ratings volume (22 vs 7) and iOS requirement (10.0 vs 15.1). On price, review sentiment and device support there is nothing between them.
