Simplified Brainwave iOS App Development

We are looking to develop a simplified iOS app for brainwave modulation. The app will feature:

1. UI (Single Screen):

• Programs: Reset / Recovery / Boost
• Volume Controls: Music (0–100%) and Frequency (0–100%)
• Timer Options: 15 / 20 / 25 / 30 minutes with START/STOP controls

1. Audio Engine:

• Signal: Fixed 40 Hz sine wave
• Program Logic with LFO Modulation:
• Reset: 0.1 Hz
• Recovery: 0.7 Hz
• Boost: 3.0 Hz
• Audio Output:
• Channel 1: 40 Hz sine wave
• Channel 2: Background audio with independent volume control

1. Session Logic:

• START → Audio + Timer Start, Program Active
• STOP → Immediate Stop + Reset
• Timer End → Auto Stop

1. Platform Requirements: iOS (iPhone + iPad), Offline Capable

2. Constraints: No user accounts, no data storage, no backend required

3. Future Scope: BLE hardware integration (ESP32) and external vibration device control Budget: USD 250–500 Skills: Mobile App Development, iPhone, Objective C, iBeacon, Bluetooth Low Energy (BLE)
