I built an AI that only works when my phone is in my pocket

Description and use

Drift generates walk rules with Gemma 4, reads them aloud with Kokoro, tracks screen‑time to keep the phone in the pocket, and logs a brief notebook entry after the walk.

Problem

Users want a walk app that encourages leaving the phone in the pocket and not looking at the screen.

Outcome

Drift recorded 2 min 5 sec of screen‑time during a 10‑minute walk, demonstrating that the phone stayed in the pocket. The notebook entry was "Thank you." due to Whisper’s silence handling, leading to a new check for short or quiet recordings.

Workflow

• Open Drift in Safari on iPhone
• Select a mood and duration
• Press Prepare to generate rules with Gemma 4
• Listen to Kokoro read the rules aloud
• Walk while keeping the phone in the pocket
• After walking, speak a minute about observations
• Whisper transcribes the speech on device
• Gemma writes a notebook entry
• Drift records screen‑time and saves data

Evidence
