So today I'm publishing my first app! :]
MATHTools is a collection of handy tools for high school (and early university) students who deal with math.

}
It all started as a small weekend project in Feb 2013; but I started experimenting and adding features little by little and continued to make it better. MATHTools is a tiny open source app that offers a handy set of tools in a nice, clean and modern interface.
As I got into university, the app was left off for a while, but I decided to publish it and work on it again if others also find it useful.
I'll need your help to make this app better and further usable. So, your feedback is always welcome. Please use the "Feedback" option in the action bar and tell me which features you would like to see!
Here's a list of currently available tools:
Vectors:
- Vector Multiplication ( dot and cross product )
- Vector Projections (2D/3D - scalar and vector)
- Line Analyzer (2D/3D - parallel/skew/identical/intersecting lines)
Geometry:
- None (yet)
Trigonometry:
- None (yet)
Calculus:
- None (yet)
As you see, three of the four sections of the app don't have any tools yet. I have a couple of ideas in mind, but I will definitely need your help to prioritize them. For instance, would you like to see cheat sheets as well, or do you prefer the app to be focused on actual tools?
As mentioned earlier, MATHTools is open source, so, contributions are much appreciated! Feel free to browse the source code on GitHub: https://github.com/aminb/mathtools
More screenshots on Google Play (for some reason can't attach more here right now).
So, please download the app and give it a try; I know there's quite a bit missing which I'll be adding over time; and let me know what you think!

Hi everyone,
I hope I am posting in the right section.
I recently released my first personal published app to the Play Store. It has ads, but those will soon be removed - chose to include them to learn how. I also have my code as open-source if anyone wants it.
Link is at the bottom of this post.
My app is unique in that it does several network requests to foursquare api and google places to aggregate and populate a listview.
My favorite and most exciting feature was implementing a compass AND pointer using sensors, gps data, and a lot of math. Took me a lot of hard work just for this first main version.
The compass always points mag North regardless of which way you turn and also has an arrow that points at the moving target based on real-time sensor/gps/API data.
Still a few bugs that but I'm taking a break from the app so I can come back in a few weeks and refactor + add new features.
This app will display real-time interactive location data for food trucks/trailers/food stands etc.
It should work on any device at any orientation. My custom interpolation makes a smoothe compass/pointer.
Any feedback and support would be greatly appreciated as I am job hunting and it isn't easy by any means, as some of you know. The more I can implement changes/feedback from reviews (hopefully) and/or here, the better prepared I'll be for Dev positions.
Thanks to anyone that downloads the app. You guys on this entire forum are awesome; I mostly use it for updates on kernels and roms, but first time I'm posting on a published app in the Play Store. Thanks everyone.
Cheers,
Justin

I do not believe that XDA allows posts to advertise paid apps without having at least a free version available. You may want to check up on that.
Against forum rules. Post a free version also or this thread will get locked and or deleted.

Good morning dear XDA'ers,
It's been a long time since I posted on this forum. I've been working on what I call "weekend-project", which in fact was part of my bachelor thesis: a boggle solver game for android. As my thesis was in fact about client-server architectures, I decided to make this game multiplayer, so you can play wordhunt with your friends.
I know there a lot of work to do and I have a lot of features that I would like to implement like: dictionary, play with friends near-by, multiple languages and specialised dictionaries (cars, mechanics, astronomy, football, etc).
I would like to call this version a beta, especially for the fact that I don't know how the server will handle the load, if there will be many users. I'm trying to find time to improve it, but I need users to see what are its weak points.
I'll wait for your feedback and suggestions on how can I improve the game and most important if it is attractive to you.

Reserved for updates
Looking forward to next release...
Hey, so here my quick feedback:
+ cool, nice UI (nothing else expected, my friend)
+interesting, new play with words/letters
# maybe new games can be added, for example 10 words will show and u have to find as fast as possible etc..
# why ranking on main page (beside avatar), when this is always '1' or at least not related to 'top ranking'
# to less "maps". Two times behind same letters in just 2-3 games
- FC when changing username and hit save
- no information or explaining of error when register missing something or wrong entered (just showing 'login not possible')
- no showing of language. So where the words can be from. Any categories or dialects or....
- on/after register 'full name' and 'username' get connected. Maybe this should be only username (especially in game) and otherwise Frist and last name or what ever...
Surly I forgot some things, but at least u have something to start working at
CHEERS
Hey everybody!
To God be the glory, I've been making some custom roms on XDA for a while, but I have decided to try to learn some new things by taking an app developer course. I've made a few apps, and I thought I would share them here as well. This app is open source, you are welcome to go to the Github and post issues, review and or copy the code (it is Apache-2.0 licensed), or download the app and enjoy!
These are my first apps, and I know they need a little improvement. So please feel free to leave a comment! But please remember, the best criticism is constructive.
If you do check out my Github, note that just about every line of my code includes a comment as to what it does or why it exists, so if you are like me and new to Android programming, be sure to check it out to see how it works! Also, in my Github are many "small apps" in the "apps_small" repo, which are apps I either made for the class, or made on the side to test out some feature or function. Hopefully that would be useful to someone.
Without further ado:
Critical Velocity!
This is a classic arcade style, side scrolling app. You are the captain of a small spacecraft that is trapped in an underground tunnel of a planet that is collapsing. Your ship is damaged and it is all you can do to keep the spacecraft aloft. As you travel through the tunnel you pick up speed and travel becomes more difficult!
This is not an unending tunnel, though! Once you reach 25,000 points you will find the exit! Can you make it Captain?
Best of all, this open source app has NO ADVERTISEMENTS!

Hi Folks,
some time ago I had the idea for an application which helps the user to navigate between applications fast and smart.
And after a few weeks I ended up with my Applications called Nano Next.
It's currently helping me a lot, and hopefully it will help some of you too.
If I can see a good need of the App, I'll continue to work on it. There are a lot of new and helpful features I want to include step by step.
Therefore, feel free to download and give me feedback
Some screenshots:

First of - great work.
It's a different kind of Application, I tried it and using it by creating an "entertainment scene" which (by surprise) really is helpful .
Looking forward for more features, seems kinda like a first implementation of your idea.
@XDA_Checker,
thank you very much for the feedback
Yeah you're right it's kind a like a first implementation. But I am currently working on a new feature which will make the whole application a lot more interessting and usefull.
Allowing to define if and which system settings (Screen Brightness, Audio volume, Bluetooth, Wifi etc.) should apply if a scene is started.
Here some screenshots of the current state:
Uploaded a youtube video about how my application is working.
AND: New feature "Define System Settings on Scene start" is live!!
Youtube:
This looks good. Nice work. I'm thinking this could be really helpful for location-based productivity as well (not just subjects). I'm going to install it and set up a scene for my gym, one for work and then try some subject ones like social and news.
really looking forward to trying this out : )
Thank you @Garethbjenkins.
Really really glad to hear that
If you have any feedback or improvement suggestions just write me. I'll love to add it
Hi all,
after a while just published a new version with many stability and UX improvements.
