What is LanDroid?

LanDroid is swiss army knife of network tools for Android OS with simple and handy interface.
Initially created for my personal needs (there weren't many good network information and troubleshooting apps available in 2010) released publicly on Google Play in 2011.
Landroid is a free application without Ads and annoying stuff and will always remain such (Please don't send me monetization offers).

There is no documentation available. This app is intended for network experts and has very simple interface. If you need information about some of the tools just search for it's name in Wikipedia.

(Yep, I receive a lot of such "requests")
LanDroid is not a hacking tool. It's a network troubleshooting tool. There are plenty of free online resources and trainings if your are interested in IT security.

The uniqueness of LanDroid is it's tiny size, lightness and backward compatability. This is part of my philosophy, I love the simple and minimalistic things. If I decide to create a paid application, it'll have all the good stuff for sure.

An example: In the LocalNet tool, in order to be able to view the wifi SSID/BSSID on modern Android versions you need to grant Location permissions (a privacy measure by Google). If I add an automatic, interactive request for location permission, I'll have to include additional library which will add 1MB to the app size (60k) and break the compatibility and support for many old devices.


- This update targets the latest Android API (34) to meet the new GooglePlay requirements and keep the application available in the Playstore.
  (For details:
  As a result of the above change, the following LanDroid features have been disabled:

Android 10 (API level 29) introduced many privacy changes and restrictions.
