Welcome to the EchoVis Quiz game. We hope that it will help you improve your hearing sensitivity – and its effectiveness. It will increase your skills in the field of recognizing sound propagation in various environments, its reflections, distortions, and the knowledge of the echolocation phenomenon. The main objectives of the game are: • Improving the ability to use the hearing organ, • Learning the skill of using echolocation, • Providing entertainment through competing with other players – ranking. The game essentially targets anyone without a significant hearing dysfunction. You can play it with, and compete against your family members, friends or yourself. Its educational aspect is also vital in the case of the blind and visually impaired. The game makes it possible to get accustomed to sounds in different spaces: at home, in the forest, between buildings, on busy streets, inside such structures as train stations, etc. All the above can be achieved in the safe and peaceful surroundings of your home. You do not have to go anywhere. We will “teleport” you to many interesting places. All you need are your headphones, a smartphone, and our app. Each of the questions and the suggested answers relate to a sound recording. Questions are illustrated using various audio recordings: classic stereo, binaural recordings and other. This is why we strongly recommend using proper headphones that enable receiving stereo-quality sound. In the light of the above, correctly putting the headphone on the proper ear – right and left – will be crucial. More advanced users can also use adequately spaced speaker sets for this purpose. Some of the recordings were made in a specially prepared space using reflective or sound-attenuating walls and clickers that emit waves of various frequencies. They enable testing yourself under highly demanding acoustic conditions and learning to focus on very specific aspects of various sound phenomena. The game contains packages comprising 50 recordings. The number 0 package is free of charge. You will have to pay a small amount for each subsequent one. The first edition contains packages 0 and 1. We plan to deliver successive ones in the future. We wish you productive learning and high-ranking records. ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Package 1 | $1.99 | one-time | | Package 2 | $1.99 | one-time | | Package 3 | $1.99 | one-time | | Package 4 | $1.99 | one-time | | Package 6 | $1.99 | one-time | | Package 5 | $1.99 | one-time | ## Version history (last 5 releases) ### 1.1 — 2024-11-26 "There's more going on behind the scenes of the app than you might think!" 
 In this version, we focused on improvements and fixes: 
- we've eliminated a few annoying bugs, 
 - we've made the app more responsive, - we've improved the stability of the app, - we've optimized the app's performance with the latest versions of iOS, - we've updated external libraries. ### 1.0.3 — 2024-02-09 Enlarging the font in the system no longer causes a conflict when using the game - the application screen is scaled appropriately and answering questions is possible. While a recording is playing, VoiceOver no longer announces an on-screen progress bar. Thanks to this, listening to the recordings is not interrupted. Since the last update, we have added several new sets of questions to the application. We encourage you to check if you answered all of them. ### 1.0.2 — 2023-03-02 Added a second paid bundle of questions (Package 2). Includes 50 new questions. Improved the action of the gesture that allows you to interrupt the playback of the recording - double tap with one finger. Optimization of application. Fixed bugs. ### 1.0.1 — 2023-01-19 - Bugfixes ### 1.0 — 2022-12-30 No release notes. ## Apps similar to EchoVis Quiz | App | Rating | Price | Category | | --- | --- | --- | --- | | [Round Logic](https://appshunter.io/ios/app/round-logic/id6736708666) | 4.0 (1) | $2.99 | Games | | [Nono Blocks Formula](https://appshunter.io/ios/app/nono-blocks-formula/id6695739680) | 5.0 (5) | Free | Games | | [Brailliance - Learn Braille](https://appshunter.io/ios/app/brailliance-learn-braille/id6478794947) | 4.6 (50) | Free | Games | | [SoundEcho](https://appshunter.io/ios/app/soundecho/id1639116371) | 4.5 (2) | Free | Games | | [Call-of-Fate](https://appshunter.io/ios/app/call-of-fate/id6478996409) | 3.9 (15) | Free | Games | | [Purple Friday](https://appshunter.io/ios/app/purple-friday/id1502985046) | 4.0 (5) | $2.99 | Games | ## More apps by Transition Technologies S.A. - [Seeing Assistant Home](https://appshunter.io/ios/app/seeing-assistant-home/id625146680) - [Seeing Assistant Move](https://appshunter.io/ios/app/seeing-assistant-move/id625286820) - [Seeing Assistant Light](https://appshunter.io/ios/app/seeing-assistant-light/id690177283) - [Seeing Assistant Magnifier](https://appshunter.io/ios/app/seeing-assistant-magnifier/id692742390) - [Miasto Szkła Krosno](https://appshunter.io/ios/app/miasto-szka-krosno/id864959405) - [Seeing Assistant AlarmGPS](https://appshunter.io/ios/app/seeing-assistant-alarmgps/id945957265) All apps by Transition Technologies S.A.: https://appshunter.io/developer/388173587 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
