Osia Smart
Cochlear Limited
A phone app for controlling compatible Cochlear Osia sound processors and supported wireless accessories.
What Osia Smart does
Osia Smart brings supported processor controls to your phone. You can change programs, adjust volume and access processor status. The app also documents sound adjustments, saved favourites, usage information and a processor finder. Some features require a Cochlear account, while phone and processor compatibility must be checked for the exact setup.

Osia Smart and Baha Smart offer similar volume, program and accessory controls, but serve different Cochlear processor families. Choose the app that supports your exact processor.
Saved sound adjustments, like Baha Smart
Like Baha Smart, Osia Smart includes an equalizer and favourites for saved adjustments. Some steps require a Cochlear account.

Availability & access
Privacy & data
- Supported: Delete account3
- An account unlocks additional functionality; this does not assert that every basic control requires login.
- Applies to Remote Assist, not all basic local controls. Remote Assist is explicitly unavailable for Osia 2/2(I) sound processors.
- Request closure from My Account; the publisher says completion can take up to 10 days and affects all Cochlear online services.
- Separate sliders require a bilateral processor configuration.
- The current documented equalizer workflow requires login.
- ForwardFocus is one of the login-required presets on eligible processor models only; exact model support is not established here.
- Rechargeable processors show percentage increments; for single-use batteries the indicator appears only at low battery.
- Location/find features require the appropriate app permissions and, in the current help workflow, a Cochlear account.
- Requires a logged-in Cochlear account linked to a participating clinic and a country where Remote Assist is offered. Remote Assist is explicitly unavailable for Osia 2/2(I) sound processors.
- The clinician can adjust a supported processor during Remote Assist; availability depends on country, clinic enrollment and compatible hardware. Remote Assist is explicitly unavailable for Osia 2/2(I) sound processors.
- Creates saved sound adjustments; available programs and app login requirements depend on the current supported processor workflow.
- Only compatible paired Cochlear wireless accessories/devices are included.
- Basic supported app controls. Remote Assist excludes Osia 2/2(I), and functions depend on processor generation.
App Store ratings & reviews
Complaints
- Other reviewers describe saved settings reverting, limited controls or confusing icons/navigation; several request clearer explanations and more direct program selection.
- Sampled users describe processor pairing/reconnection problems, slow or stuck screens and update-related disruption across 2021–2026. Reports concern specific phones or bilateral setups and do not establish present prevalence.
- Some comments report account creation/login failures or trouble using the processor finder, including 2024–2026 reports. These are user experiences, not verified current service or location-accuracy findings.
Google Play ratings & reviews
Complaints
- Reports describe particular Android pairing/connection difficulties and frustration about streaming/call limitations. Those comments mix app controls, phone support and accessory requirements rather than establishing an app-only defect.
- Some reviewers request persistent volume settings, clearer navigation/battery information, or better bilateral controls; a November 2025 comment dislikes the changed program-navigation layout.
Mixed reports
- A June 2023 reviewer says moving controls above the Android navigation buttons improved usability; other older comments report working controls or responsive support. These do not prove a current general fix.
