Ambi is a free iPhone app developed by Mellowmuse Ltd. It falls under the lifestyle category, specifically in the Health & Fitness subcategory. Ambi is designed to aid relaxation and concentration by masking extraneous background noise with ambient sounds.

Unlike many other apps that use repetitive audio loops, Ambi generates an ever-changing mix of white, brown, pink, and water noise that never repeats. This unique feature ensures that users are not disturbed by predictable patterns and can fully immerse themselves in the calming and soothing sounds.

With Ambi, users have the ability to manually adjust the mix of ambient noises by dragging a sphere on the mix screen. Alternatively, they can enable the "motion" feature to automatically randomize the mix. This allows for a customizable and dynamic listening experience.

To enhance the overall audio experience, Ambi offers the option to add reverb, which increases the sense of depth. Additionally, the app provides an 8-band graphic equalizer, allowing users to sculpt the audio to their personal preferences.

For added convenience, Ambi offers an in-app purchase option to access a built-in timer. This feature automatically switches off the audio after a specified period, allowing users to set a duration for their relaxation or concentration sessions.

Furthermore, Ambi provides user presets, enabling users to create, edit, and save their favorite equalizer, reverb, and motion settings. This feature allows for easy customization and quick access to preferred audio configurations.

Overall, Ambi is a versatile and user-friendly app that offers a unique approach to ambient noise generation for relaxation and concentration. Its ever-changing mix of ambient sounds, customizable features, and convenient presets make it a valuable tool for those seeking a tranquil and focused environment.
