# P2P (peer-to-peer) App Updates
**Peer-to-peer (P2P) App Updates** is an experimental feature that allows you to share and receive newer versions of the Mapeo app by connecting to other Mapeo devices via Wi-Fi (no internet connection required).
When updating the Mapeo app version in this way, **NONE** of your Mapeo data (observations, configurations, or maps) is shared between devices.
To search for and share Mapeo app updates between Mapeo Mobile devices, both smartphones must:
* have the P2P App Updates feature enabled
* have Mapeo open to the **Synchronize** screen
* be connected to the same Wi-Fi network
### Turn on the P2P App Updates feature
To use this feature, you will need to enable it within the **Experiments** menu. To do so, tap the 
**Observations list** button, then tap 
**Settings**, and select **Experiments**. Select **P2P App Updates,** then check the box to **Use P2P App Updater**.
 
### Check for available updates
Once you have enabled the P2P App Updates feature, you will be able to use it on the 
**Synchronize** screen.\
