Mobile App Development Case for SnoozeBand

Device · Bluetooth · Mental

SnoozeBand is a Bluetooth headband designed for sleep & an active lifestyle. In this app, users pair their SnoozeBand via Bluetooth to gain access to a curated library of audio content, such as meditations and ambient soundscapes designed to help them fall asleep faster and improve overall sleep quality. Additionally, the app allows users to set their bedtime reminders, ensuring they establish and maintain a healthy nightly routine.

Client Requirement

 Our task was to develop an application that extends the functionality of the SnoozeBand, serving to elevate the user’s sleep and active‐lifestyle experience. Once users pair their SnoozeBand via Bluetooth, they gain access to a carefully curated audio library—organized by themes and collections—where they can browse, stream, and create custom playlists. The app also lets users schedule and receive personalized bedtime reminders to reinforce healthy sleep habits, and download favorite audios into a dedicated offline playlist for uninterrupted use even without connectivity.

Technology Stack

Flutter BLoC (especially Cubit) as state manager, Supabase as BE solution, just_audio and audio_service as audio player management libraries, RxDart as tool for stream behavior optimisation

Outcomes

Device-Based Content Unlock

Users gain full access to the curated audio library after successfully pairing their SnoozeBand device for the first time. Once unlocked, the content remains available in the user’s account without requiring the device to be reconnected in future sessions. Before pairing, only a limited demo selection is accessible for trial purposes.

Curated Audio Library for Better Sleep

The app offers a collection of meditations, ambient soundscapes, and sleep-enhancing audio, organized by themes and collections. Users can stream content or listen offline, helping them improve sleep quality and overall well-being.

Custom Playlists and Favorites

Users can create personalized playlists, add or remove audios, rename playlists, and mark favorite audios for quicker access, offering a highly customizable listening experience.



Bedtime Reminders

The app allows users to set personalized bedtime reminders to encourage consistent sleep routines and promote healthier nightly habits. 

Offline Listening Mode

Users can download audios into a dedicated offline playlist, enabling uninterrupted playback without the need for internet connectivity.

Secure Registration

The app supports secure registration and login using email and password, with built-in password setup and recovery features—ensuring smooth and protected access to user accounts.

Admin panel for content management

We have developed a simple, intuitive admin interface that allows the client to upload videos and manage all metadata associated with the audio: descriptions, cover images, topic tags, etc. This allows admin to add, edit or delete media assets without developer intervention, streamlining content updating and publishing.



Challenges

Challenges

Cross-Platform Bluetooth Device Integration

One of the core challenges was ensuring reliable Bluetooth connectivity across both Android and iOS platforms. Since the two systems handle Bluetooth communication differently, we had to implement platform-specific logic to manage device discovery, pairing, and connection states. Additionally, it was crucial to guarantee that once the SnoozeBand device was successfully paired, the app would unlock access to the full audio library—and persist this unlocked state for the user’s account moving forward.



Audio Player and Playlist Synchronization

Another major challenge involved implementing a seamless audio playback experience combined with dynamic playlist functionality. This included managing playback controls, real-time syncing between track status (e.g. downloaded, favorited, playing), and user actions across screens. The offline mode required careful handling of locally stored audio files, ensuring smooth playback without connectivity
