ReDi
MED-EL Elektromedizinische Geraete GmbH
Independent auditory and speech exercises for hearing-technology users.
What ReDi does
ReDi offers independent auditory and speech exercises for users of hearing aids and implants, with several difficulty levels and immediate feedback. Adults can work through ready-made courses and optionally connect with a speech therapist. Some noise-training courses are specifically documented for US English.
How it compares
Independent access rather than Lace Pro’s provider setup
ReDi offers ready-made listening exercises you can use without a practice partner. WordSuccess also supports independent practice, while Lace Pro access is set up through a hearing-care professional.
Optional therapist access versus provider-led setup
ReDi lets you grant a therapist access to customize training and review progress. Lace Pro also involves a professional in access and progress review, while WordSuccess needs no provider setup.

App Store ratings & reviews
Complaints
- A September 2024 reviewer found instructions and completed-activity status hard to locate and could not undo skipping; a 2021 reviewer said the text-display setting did not work. These are dated usability reports.
Mixed reports
- The seven captured iPhone comments include appreciation for the exercises and replay, alongside 2024–2026 reports of incorrect-looking answer scoring, incomplete audio sequences or activity errors. No versions were captured and these reports do not establish measured rehabilitation benefit or an app-wide current defect.
Google Play ratings & reviews
Praise
- Several 2025–October 2026 Android reviewers valued word/listening practice, with one finding the starting levels easy. Statements about relearning hearing are personal experiences, not evidence of effectiveness.
Complaints
- March 2025–October 2026 Android comments reported spoken words apparently marked incorrect, including version 3.8.2; other 2026 reports described server errors, interrupted lessons or lost implant audio connection. Causes and current reproduction were not verified.
Mixed reports
- A 2025 comment objected to mobile-data use; 2021 and 2026 reviewers wanted more material or a better difficulty fit. The 2021 limited-content account is historical and does not describe the current catalog.
