PopQuiz! for Android and Windows will test your knowledge in the subjects of Chemistry, Physics and Math with over 500 randomly selected questions to answer. As each question is displayed on the screen, they can be answered by typing on the virtual keyboard to progress - but be warned, you only have 10 seconds to answer each question.
While the user interface is kept basic, this isn't an app that relies on pretty visuals to get the job done - which is to test your knowledge, and some of the questions can be tricky enough to revise and refresh your understanding of the subjects.
A recent update added achievements and leaderboards which you can share with your friends, and because the app is free for Android, you may find PopQuiz! a worthy addition to your brain-teasers.
Tree Notes (by Dextronet) takes an interesting approach to note-taking; ditching the common sticky-note method in favor of a collapsible tree containing various items and projects in the left-pane, and a rich-text editor to the right, which can contain notes, emails and embedded files to keep track of daily tasks and events.
Items can be distinguished with a selection from over 244 icons provided, and your notes can be stored in a local database with optional encryption to keep out prying eyes.
It's all fairly intuitive, and the ability to export to PDF, along with searchable notes and a built-in spellchecker makes this a good all-round organizer for personal note-taking.
Skin and Bones (by Addictive 247) is a retro-style platformer with a simple premise; to complete each level you must switch between two characters, each with unique abilities that will help or hinder your progress through the tricks and traps laid out across 6 varied worlds.
Skin, who appropriately enough actually has skin, is fast and agile, and spends his time using skeletal co-protagonist, Bones' head as a handy platform to cross spikes and lava to reach shiny gems strewn around the level.
While the graphics don't jump out as anything special, this game really shines in the gameplay department. Switching between the two characters to complete each level is genuinely fun, and well worth a look!
Game developers can be quite demanding when it comes to their development tools and editors, especially given the broad range of model formats, graphics APIs and game engines they have to work with - and the options for 3D modelers are well established with the likes of 3DSMax, Z-Brush and Blender - many of which require you to jump through hoops and plug-ins to export game-ready models in a suitable format.
deepMesh provides a feature-rich set of 3D model editing tools for game developers, which may be more accessible to beginners than some of the alternatives, while giving seasoned 3d artists every editing tool they could wish for in a single app.
Every stage of the modelling process is catered for, from model editing to materials, uv mapping, light & shadow and even an integrated scene-editor make deepMesh a worthy addition to your development tools.
Bus Driver (by SCS Software) is one of those simulation games that allows you to experience the thrills of something actually not very thrilling, while being strangely enjoyable for enthusiasts and gamers who take their driving [far too] seriously.
There's a good selection of buses on offer, and plenty of variety in the environments as you slowly crawl to each stop to pick up passengers, who stand there like mannequins before teleporting (you have to use your imagination here) onto your shiny bus.
The game is so slow-paced and quiet, the biggest danger to your passengers is you falling asleep at the wheel - so it's a nice touch that they'll scream and panic at the slightest hint of bad driving, making the urge to plow your bus into oncoming traffic irresistible.
As close as you'll get to driving a bus without actually driving a bus. Don't expect high-speed chases or screeching tires, Bus Driver expects you to obey the rules of the road, pick up passengers and use turn signals. If you like buses, you might want to give it a try.
