Market Link: market.android.com/details?id=com.shakti.rayoptics
Ray Optics is a very important topic of Physics and this app can help you to understand and visualize it. You can see ray diagram and image position in real time for any setup of lens and mirrors. You can also understand concepts of reflection and refraction and their implication in real time.
This will be of interest to all students (/teachers) studying (/teaching) Ray Optics and all other people in love with Physics (like me)
Features:
- Geometric optics simulator
- Refraction and reflection with full ray diagram support
- Editable object, lens and mirror properties
Support for
Concave and convex lenses
Concave and convex mirrors
Glass slabs
- Formation of Virtual and real images
- One advance feature is that you can even shift principal axis of lens and mirrors. ( for real geeks )
GUI Features
- Dragging axis
- Pinch Zoom
- Hiding of button/text panel on long press
* Based on thin lens equation

Roadmap (in 1 year):
The current features are superrr simple, just preview and take pictures with front and back cameras. In the future, I wanna integrate more cool features:
+ More virtual glasses
+ Photo editor: allows user to select photo from gallery, then wears on virtual glasses
+ Real-time skin / hair segmentation: users can change their skin/hair colors virtually (this requires a custom tensorflow lite model)
The current app uses google ML kit, not sure it works perfectly on many android versions or phones. Please let me know if there are some bugs.
To complete the roadmap, I only need motivation from users (you) at this time.

[APP][1.6+] Tilt Timer for balance board exercise

**Update:** App renamed to Balance Timer.
I made myself a round wooden balance/wobble board for balance training, and I've always wanted a way to measure how much time I can stay balanced. Finally I realized I could do this very easily with an accelerometer, and Balance Timer is born: a simple stopwatch activated by tilting. You need to set the stop angle to match your balance board, and then you can just put your phone on your board (works best if you have a grippy case). It's probably also a good idea to calibrate the accelerometer by pressing the menu button and Calibrate. When you straighten out the board, the stopwatch will start and when the board angle gets close to touching the ground it will stop, at least if you've calibrated correctly.
Now up on Google Play.
The apk and source are also in github: https://github.com/arpruss/tiltstopwatch/blob/master/app/release/TiltStopwatch-release.apk
The code is adapted from my free Giant Stopwatch app.
