# What Is App Versioning and Why Do You Need It?

**App versioning** keeps a history of an internal app's states, lets you pin which one users see, and allows any earlier version to be restored. Changing a live tool stops being a risk.

## The problem it solves

Without versioning, every edit is immediately visible to everyone using the app.

- A field removed while someone is mid-task
- Layout changing without warning during the working day
- Experiments impossible without affecting the team
- Critical apps left untouched out of caution

## How versions behave

| Concept               | What it means                                   |
| --------------------- | ----------------------------------------------- |
| **Published version** | What everyone sees by default                   |
| **Auto-publish**      | The default — changes go live as they are made  |
| **Pinned version**    | A chosen stable state stays live while you edit |
| **Restore**           | Brings back an earlier state as a new version   |

## How to use it in Jestor

1. Open version management for the app in **Jestor**.
2. Switch off auto-publish and pin the stable version.
3. Edit with build mode on — changes accumulate in a new version.
4. Turn build mode off to preview exactly what members currently see.
5. Restore an earlier version if a change proves wrong; the history stays intact.

## Why choose Jestor for safe changes?

The practical value of **app versioning** is that restoring in **Jestor** generates a new version rather than deleting the intervening ones, so going back is never destructive and the full history remains available.

Members cannot reach the draft version at all, which means an unfinished change is genuinely invisible rather than merely unlikely to be found.

## Frequently Asked Questions

### Do users see my edits immediately?

Only if auto-publish is on; pin a version to prevent it. See [jestor.com](https://jestor.com/?ref=blog.jestor.com).

### Does restoring delete later versions?

No, it creates a new version from the one restored.

### How do I preview what users see?

Turn build mode off.
