Trail Notebook: a phone that hears the birds and writes your field notes, with no signal

说明与用途

Trail Notebook 是一款离线移动应用，使用 BirdNET 和 Gemma 3 1B 识别鸟鸣并自动生成现场记录，支持无网络的徒步工作。

问题

Field researchers need a way to identify bird species and record observations while offline on trails where network signals are unavailable.

结果

After a one‑time 748 MB download, the app identifies bird species in 282 ms, generates a note at 39 tokens/s, and requires no network thereafter, enabling reliable fieldwork in airplane mode.

工作流

• 1. Enable airplane mode and hold phone near a bird call.
• 2. Tap the Listen button to record 9 seconds of audio.
• 3. BirdNET V2.4 processes the audio and displays the top species with confidence labels.
• 4. Gemma 3 1B generates a two‑line journal entry (NOTE and NEXT).
• 5. Entry is saved locally with timestamp, optional spot name, approximate location, and offline stamp.

证据

748 MB downloaded once. 282 ms from end of listening to species. 39 tokens/s from Gemma. Zero network after that.

来源

BirdNET V2.4 (6,522 classes) runs on the phone. You see the top species and up to two alternates, with a confidence word ('very likely', 'likely', 'possible') instead of a raw score.

来源

Gemma writes the same NOTE and NEXT, and the prompt tells it not to name a species you didn't.
