Wifi Share Lite for Android
For example: You are in mountain with other persons, then take one or more pictures and want share with them.
The simplest way to do, it's select the pictures and give the possibility to download instead of send on each device one by one.
Then, select files, setup wifi access point and start sharing.
The clients can connect at your's wifi network and download files via browser at address showed on your device.
NOTE:
If you have an isp able to detect if your phone run as a router, then disable APN DATA before use that application. Some isp detect that and get money from you.
