It’s Sunday, the time of the week when Cult of Android brings you its report on some of the very best apps we have been using throughout the past week.

This week we have been trying out a great photo sharing app, a reliable instant messaging app, a festive live wallpaper and a useful digital clock widget.

Cluster:

Up first this week we have Cluster, a very simple, yet useful, photo sharing application which encourages its users to invite family and friends to add photos surrounding a specific topic or event, such as a birthday, a wedding, a party, a holiday, etc. This gives users the ability to create gorgeous interactive photo albums, which includes the contributed images.

In addition, Cluster automatically stores and organizes your photos based on the time and location they were snapped. These pictures are then uploaded to Cluster’s secure server and users will be able to access them from within the app or on the web at anytime.

Cluster is free to download on Google Play and you can grab it by clicking here.

Imo Messenger:

Secondly, we have Imo Messenger, which is by far one of the most well-known and reliable instant messaging services in the world. Imo allows its users to send free pictures, texts and voice messages to friends, as well as now giving them the ability to engage in completely free high-quality video and voice calls over Wi-Fi or a cellular connection.

Furthermore, users will be able to store and access compatible web-based messaging accounts in one place, so they’ll be able to engage in conversations using a multitude of different instant messaging services without having to leave the application. At this precise moment in time, the Imo service provides users with support for Facebook Chat, Google Talk, ICQ, AIM, Yahoo! Messenger, Jabber and Steam.

Christmas Countdown Live Wallpaper: 

Christmas is approaching extremely quickly and to get us in the festive mood it’s only right that we feature a festive live wallpaper. This week, we have been trying out a rather enjoyable Christmas Countdown live wallpaper, which, provides its users with a live countdown up until Christmas day.

Once installed on a user’s device, their wallpaper will change to a traditional “Christmas Scene” with a Christmas Countdown timer embedded in a snowfall of lights. In the centre of the screen, you’ll find a Christmas tree which can be rotated by dragging your fingers across the screen.

ClockQ – Digital Clock Widget:

Finally, we have Clock Q, a  clean, customizable, informative and powerful clock widget for any Android smartphone or tablet running Android 1.6 Donut and above. Users will have the ability to adjust the size of the clock and alter the color of the widget.

In addition, they will also be able to display ClockQ as their official lock screen clock – providing they’re running Android 4.2 or higher.
