Are you myopic? Do you want to use your phone to test your vision? Come and test your vision. Our vision test is an easy-to-use vision test tool. This app makes full use of the sensor characteristics of touch screen, intelligently tests and determines your vision and the accuracy of result almost reaches the level of specialization. After testing, you will be able to know whether you need to see an ophthalmologist. Vision test is based on standard charts (Snellen chart, LogMAR chart, Golovin-Sivtsev form, Landolt C / Japanese visual test, Tumbling E chart).
Our App Features:
a. Very simple eye test steps
b. Humanized test method enables you to switch the test operation to left hand or right hand.
Disclaimer:
The vision test may not be perfect due to different screen PPI (screen size, brightness / contrast, resolution).
The test can only help you get to know your eyesight.

A pair of security researchers have recently unveiled an interesting new keylogging method (PDF Research Paper) that makes use of a very unlikely smartphone component, your gyroscope.
Most smart phones now come equipped with gyroscopes, which can be accessed by any application at any time. [Hao Chen and Lian Cai] were able to use an Android phone’s orientation data to pin down what buttons were being pressed by the user. The attack is not perfect, as the researchers were only able to discern the correct keypress about 72% of the time, but it certainly is a good start.
This side channel attack works because it turns out that each button on a smart phone has a unique “signature”, in that the phone will consistently be tilted in a certain way with each keypress. The pair does admit that the software becomes far less accurate when working with a full qwerty keyboard due to button proximity, but a 10 digit pad and keypads found on tablets can be sniffed with relatively good results.
We don’t think this is anything you should really be worried about, but it’s an interesting attack nonetheless.

Hello
This is the first app I wrote for Android on my spare time. It is not groundbreaking or super complex, just a resistor calculator with reverse search capabilities. It is free on the market, I am not looking for any commercial profits but rather just suggestions (especially the UI, which I am weak at). I am looking to writing a new Grade Management App which can let a person record all their grades/weighting/courses and provide performance analysis, etc. But before I get into that, I really want to learn more about UIs from the community because I know it can be a lot better than the resistor app. So onto the app itself:
* 4 and 5 Band Resistor Support *
* Supports Reverse Lookup *
This Resistor Tool can display the resistance value based on the color bands. In addition, it can also display the resistor colors based on an inputted resistance value.
In other words, whether you have a resistor and want to find out its value or vice versa, this app can get it done.
I am a starter in Android Programming so all suggestions and ideas are welcome, thanks!

This application is built to enhance the photo quality stored in the Android contact. Android system only supports contact photo in the resolution of 200 x 200. It is not good enough to be displayed in full screen when users are using add-in incoming call screens such as Answer Calls by Gesture (ACG).
HDC can capture high quality photo from the phone camera or existing image files in your device. As usual, you are able to crop the photo before setting to the contact. The photo resolution is chosen for you automatically according to your device. No worry on wasting storage spaces on over-high quality image.

Approaching 200 downloads just after initial released for 1.5 days. Give it a try. Just have it updated. Now users can choose half screen resolution for their entry level devices. Better performance to use with Answer Call by Gesture (ACG).
Hello everyone!

I am the author of a completely new application created to increase road safety. Using the application motorcyclist, cyclist or pedestrians can impart their position, and the driver can these road users detect in real time - then a message is displayed on the widget on the type of the detected object with the specified interval estimate of the distance to the nearest object detected. It is based on WiFi, WiFi analyzes name, not connects to any network and does not mention any data between users. As far as the range is in a straight line is up to 140 meters, it is known that all turns and terrain affect the range, however, it is enough that the dispute about detecting the driver can be valuable. The application is available for free on Google Play. Could you please test the application and write me what do you think about it?
I just try to change something for the better
lots of greetings!
~~~UPDATE 1.1 AVAILABLE~~~

please, leave your feedback
Quite new interface, enjoy and leave your feedback!
Hm, I don´t understand the sense of the app.
What can i do with it????
This program serves as a mobile assistant to an engineer.
First version of the program provides solutions for the analysis of the nine single-span beams.
The most popular type of beams for designing covers and floor are selected as default sections
Double T normal beams in accordance to СТО АЧСМ 20-93, HEA, HEB, HEC, HEM, IPE, old russian and german standarts (before 1917 year!) and channels in accordance with GOST 8240-97, UPE, UPN. The calculation results depend on the steel grade, the required deflection and section type.
program uses the following steelgrades: steel S245, steel S255, steel S345.
The calculation and selection of the beams are performed on the assumption that the upper belt of beams tied along the entire length.
New in version 6 (1.0.5)
In the results of analysis and the series 2.440-2 Issue 1 tab added information
about mounting beams to columns and other beams according to joints 20 ... 25 of 2.440-2 Issue 1 (hinge joints with overlays and bolts M20 class 5.8 and 8.8).
You can download my app on Play Google now
