## The essentials

Without a network, everything depends on what you do before leaving and on your habits on site: download what you will need while you still have Wi-Fi, use a tool that saves on the device, write things down right away with date and place, and keep a copy off the phone.

## Before you leave, while you still have a network

- Pick an app that works fully offline, not just “cached”.
- Download maps, documents and models (transcription, dictation) you will need in advance.
- Sync and make a backup before losing the connection.
- Plan for power: power bank, cable, battery saver.

## On site: structure every note

1. **Write it down right away** — Write or dictate within minutes: details fade fast.
2. **Date and place it** — Date, time, place and who was there. A note template (5W, interview, lab notebook) keeps you from skipping a field.
3. **Separate facts from impressions** — What you saw and heard on one side, your interpretation on the other.
4. **Attach the evidence** — A photo of a document, a recording (with consent): in the note, not lost in the camera roll.

## When you are back

Sync as soon as the connection is reliable, reread with fresh eyes, fill the gaps while memory is fresh, then archive the trip as a single set.

## With nTilia

nTilia saves everything on the device: capture, dictation and editing work without a network. A Mission groups a trip’s notes, photos, audio and places, with 5W, interview or lab-notebook templates. “Prepare to leave” runs a sync and a ZIP export of the Mission before you lose the network.

## Frequently asked questions

### Which notes app really works offline?

One that saves to the device first and syncs later. nTilia, Joplin and Obsidian do; Notion requires making each page available offline in advance.

### How do I avoid losing notes without a network?

By keeping a copy off the phone: an export made before leaving, then a sync as soon as the network is back.

### Can I dictate without a connection?

Yes, with a dictation or transcription tool that runs on the device, provided you downloaded the model before leaving.
