i-Angel Sound
University of California, Los Angeles
Self-paced sound and speech listening practice for home rehabilitation.
What i-Angel Sound does
i-Angel Sound provides self-paced practice identifying environmental sounds and speech components, including monosyllabic words. The exercises give audiovisual feedback, and their difficulty can be adjusted as you practice. The iPhone and iPad app is offered free.
How it compares
Environmental sounds as well as WordSuccess-style words
i-Angel Sound includes environmental sounds and word-based listening tasks. WordSuccess concentrates on distinguishing similar words, while Meludia focuses on music-based listening.
Manual difficulty rather than Lace Pro’s adaptive training
i-Angel Sound lets you adjust exercise difficulty as you practice. Lace Pro adjusts difficulty as you progress and shares results with the hearing-care professional who sets up access.
Free like WordSuccess, but limited to Apple devices
i-Angel Sound is free on iPhone and iPad. WordSuccess is also free and runs on Android as well as Apple mobile devices.

Praise
- Positive comments in 2016, 2019 and December 2025 valued simple self-paced sound/word practice for early implant rehabilitation. They describe individual experience and do not establish clinical benefit.
Complaints
- A series of 2019–September 2026 iPhone reviews reported absent or truncated spoken audio, repeated replay attempts, freezing or inconsistent scoring. Some described initially usable sessions; these are dated user reports, not confirmed current defects.
- Reviews in 2019 and 2023–2024 raised small-text, contrast or text-size accessibility concerns; 2025–2026 reviews also found navigation unclear or available activities difficult to access. Current accessibility behavior was not tested.
- Several 2017 reviews requested an iOS 11 update, while a 2023 comment requested maintenance. The 2017 compatibility reports are historical and must not be presented as current OS incompatibility.
