Welcome to a fun and powerful environment for psychic training and tests using the famous Zener ESP cards! The cards were designed in the early 1930s by the perceptual psychologist Karl Zener and were originally developed to conduct experiments for Extrasensory Perception (ESP), most often clairvoyance. A Zener card deck consists of five simple symbols. In total there are 25 cards in a pack, five of each design. In the original tests, the person that conducted the test picked up cards from a shuffled pack, observed the symbol on each card, and recorded the answer of the person being tested for extrasensory perception, who would guess which of the five designs was on each card in question. This app enables you to run various variants of the Zener card test! TEST This is the original Zener Card test, which tries to determine the presence of psychic abilities. Each card is drawn from a shuffled 25 card pack with five cards for each symbol. During the test, no card faces are shown, in order to ensure a valid test result. The result is instead presented after the test. TRAINING A fun variant of the original test, where you'll see if your predictions are correct, one card at a time. Since card faces are shown after each selection, the app always draws cards from a full and shuffled deck. MARATHON A never ending marathon test session, which is perfect both for psychic training as well as a powerful form of active meditation! The app will produce new cards from an unlimited pack of cards, and you'll, therefore, be able to see your result in real-time. In addition, all the above session can be performed in two different modes: * Postcognition a.k.a. Retrocognition Knowledge of past events which could not have been learned or inferred by normal means. The app will choose the next card BEFORE you make your selection, just like the original Zener card test. * Precognition a.k.a. Future sight or Second sight The ability to see events that will happen in the future. The app will choose the next card AFTER you make your selection. *** FEATURES *** * Training, Marathon and Test sessions. * Test Certificates - Create unique and personal certificates based on your best results. * All session can run in either Precognition (the future) and Postcognition (the past) mode. * Are you better at Precognition or Postcognition? The app stores all your results, which can be viewed from the Statistics screen. * Share your results on Game Center, and compare with friends and the whole world! * Number Cards - We are all different: Some like numbers more than symbols, therefore Pro users also can run sessions with numbered cards. * Color Cards - Some like colors even more than symbols and numbers, therefore Pro users also can run sessions with colored cards. *** Support *** Don't hesitate to contact us if you have questions or feedback through email, our support site, or via the in-app buttons. We hope you'll enjoy this free app and thanks for downloading! Disclaimer The app works as exactly as described; i.e. it will not provide any nonsense results, but since the results cannot be verified scientifically, you're expected to only use it for entertainment purposes.

With multi-sensory stimulation and crowd-scale telepathy testing, True ESP creates an immersive experience that synchronizes the brain waves of users who are located around the world – enabling them to tap into a collective consciousness and push the boundaries of what was thought to be possible. Recent studies have demonstrated that binaural music and haptic stimulation at specific frequencies can induce neural entrainment throughout the brain – facilitating the interaction of users in real-time as they transmit and receive mental images with each other. Imagine touching a cello as it resonates, or hearing the echoes of waves crashing against rocky cliffs. Multi-sensory stimuli such as these have a powerful effect on brain waves, and can significantly strengthen our perceptual abilities. Before each testing round, binaural music and vibrotactile stimulation are used to synchronize the brain waves of all users. The iPhone's haptic engine can generate richly-textured resonance patterns, and True ESP utilizes acoustic algorithms to stimulate fingertip neurons with extraordinary detail. During each four minute telepathy test, users are divided into two equal groups of senders and receivers – with senders trying to mentally transmit an image – while receivers attempt to imagine what the other group is visualizing. Receivers select two images from a set of 9 cards – after which the groups switch roles, and then repeat the process again for a total of 3 rounds during each real-time telepathy challenge. A new test is conducted every 10 minutes around-the-clock, and users can participate as often as they want. From real-time test scores to live leaderboards, users can view the results of their telepathy challenges using interactive tools that keep them both informed and engaged. These detailed performance metrics enable users to track their progress, identify areas for improvement, and refine their ESP skills. Users can also compare their performance to that of other participants, gaining a better understanding of their relative strengths and weaknesses. True ESP presents telepathy scores as odds-to-one against chance, providing an intuitive and meaningful way to convey test results – as it allows users to easily understand the probability of correct answers, and appreciate the magnitude of their performance relative to chance. To help you develop and refine your telepathic abilities, True ESP features an interactive practice mode. A neural network and machine learning algorithms simulate the behavior of virtual participants, allowing you to sharpen your skills in a controlled environment that does not affect your cumulative ESP score. Featuring the same multi-sensory stimulation and interactive features as the live crowd test, the practice mode delivers an on-demand experience that you can use anytime. Invite your friends and family to participate in the Global Telepathy Study. True ESP was developed with infinitely-scalable architecture and deployed on high-performance servers in redundant data centers. This robust system enables the simultaneous testing of an unlimited number of users located anywhere in the world. Invite others to join you for an unforgettable experience.
