The hosts file is resolved in preference to DNS requests, if the hosts file resolves the hostname, the request never leaves the device; this means the hosts file can be edited to block the domain names of ad servers, third party cookies, adware, spyware, ect…
AdAway (not available on Google Play) update the hosts file to blocks any pop-up that appears while you are browsing on your device: it needs Android >= 2.1 and root access.
The main features are:

  • Choose your own sources of hosts files;
  • Add exceptions to your Whitelist if an app is not working when specific hosts are blocked;
  • Define extra hostnames in your own Blacklist;
  • Add your own (hostname, IP)-pairs in the Redirection List.

If you use Chrome and still see ads on web pages, remember to disable the “data saver” or “reduced data usage” browser option.

Unless you’ve been living under a rock or hiding in some tall grass you’ve probably heard of Pokémon GO.
With its augmented reality platform, Pokémon GO have been appearing everywhere across the world from rivers and lakes to hospital rooms, and users of the app spend all weekend trying to catch new Pokémon and train them to be the very best.

A number of users have realized that playing the game is draining their battery extremely quickly: playing for 30 minutes reduces battery life by an average of 15 percent, which is rather high in comparison to many other apps (like Facebook or email services).

The Enhancer for GO (Google Play, Source) aim is to improve the Pokémon GO experience as much as possible:

  • Show a black screen over the game when your phone is upside down (in the pocket);
  • Block touches while the device is in your pocket;
  • Dim the screen to save battery while you are not using the app;
  • Extreme battery saver;
  • Keep the screen on while playing the game;
  • Set the brightness to maximum when the app launches for better outdoor visibility;
  • Kill background processes when the app launches (only recommended for devices with <2GB ram).

It has integration for Notifications for GO (Google Play, Source) that permits to get a notification when a Pokemon is around you while the Pokémon GO app is running (it works perfectly with the Xiaomi Mi band).

Enjoy it!

WebTube is an great and open source wrapper for the YouTube website with a couple little tweaks: it allows, for example, to navigate through channels, bookmarking, connecting through TOR and playing when the screen is off and in the background, without GAPPS on your phone.

As martykan (the main developer) says, if you have any ideas or issues, don’t hesitate to contact him, every contribution is welcome.

 

Overchan is a web-browser (with custom themes) for browsing imageboards like 4chan.org, krautchan.net, 8chan, iichan.hk, hatsune.ru, Dobrochan, 2-chru.net, 7chan.org, wakachan.org and more.

What is an imageboard?

An imageboard or image board is a type of Internet forum which operates mostly via posting images.
Imageboards, similar to bulletin board systems, are used for discussions of a variety of topics. The primary focus of imageboards, however, is directed away from text posts, and is instead placed on picture posts. The two share many of the same structures, including separate forums for separate topics, as well as similar audiences.

The most popular English language imageboard is 4chan that was born in 2003, a year before Facebook, as an image and message board in the style of a similar Japanese board called 2chan, or Futaba.

Some features of Overchan:

  • Separate preferences for each imageboard: password for post deletion, HTTP/SSL, proxy;
  • Automatic hide posts and threads using regular expressions;
  • Automatic update all open tabs in background (optional);
  • Sending posts in background;
  • Saving threads with all attachments in HTML with Dollchan Script;
  • Two ways to display replies to posts: as separate references and as list;
  • Supports the tablet interface;
  • Themes.
