I've created an app that let users to generate letters in English.
Link to Play Store: play.google.com/store/apps/details?id=com.jp.english.letters
Letters are put into categories. Users choose a category to view letters inside it. To fill a letter, you just need to choose sender and recipient and fill parameters.
With the letter generated, you can then save it, share it, print it or email it.
I need feedback because it's not easy to find good english letters templates.
In fact, this app could be more complete with more relevant contents and more translation. It would then be useful to more people.
Of course, I would appreciate suggestions and anything to improve it.
Hello!
It's my first decent android application, which took something from Spritz and a bunch of similar apps from Google Play market. When I saw that there's no suitable android app for me, I decided develop it myself. Results are below :laugh: :
Readily is a speed-reading android application powered by RSVP(Rapid Serial Visual Presentation) technology. With it you can read up to 1200 words per minute instead of 220 when reading normally.
MAIN FEATURES
Parser of a text:
Normalizes: parser checks text for and fixes bad characters and duplicates of punctuation, proper spacing before and after punctuation. Also it splits too long words in smaller ones. After that text is becoming easier to comprehend.
Emphasizes: every word is processed in order to choose emphasis position - red letter's one, which gains maximum of your attention and helps you recognize the word in the fastest way.
Sets delay(optional): when you reading on such a speed, you can miss an essence of sentence. Therefore, parser sets gentle delays before punctuation, on digits and on long words to help you grasp information clearly.
Handy controls:
You can change speed on the go - just swipe to top or bottom.
To pause or play just tap the reader's window.
Storage of incomplete readings:
Preview of next words in a paragraph (opitonal).
Dark theme to comfortable reading in the night.
Optional font size.
SOURCES OF TEXT
Clipboard: you can simply paste text to Readily.
Internet: read your favorite articles from the net or share them from other reading application.
File storage: choose .txt, .epub or .fb2 file to read using Readily.
LANGUAGES SUPPORTED
English
Russian
Ukrainian

I'd like to share CAD Reader to you. It's faster and more powerful than many other CAD viewers which you will like.
Google Play link: https://play.google.com/store/apps/details?id=com.glodon.drawingexplorer
We serve professionals from the AEC and machinery industries who need to measure, add comments, and find text when viewing drawings.
Core Values
Lightweight: It's amazing that such a powerful tool only takes up 12 MB hard disc space.
Simple: It is easy to install and use without cost of learning.
Fast: It‘s the fastest CAD viewer we can use on mobilphones.
Function Overview
1. Comment: You can comment by drawing lines, entering words, and adding records or photographs whereever you want on the drawing.
2. Measure: Specify start and end points to measure length.
3. Add comments to any coordinate as needed on the drawing.
4. Find text: Search the entered word(s) in the drawing.
5. Others: Layer Settings, Layout Switching, Horizontal/Vertical, Zoom All, Full Screen, Hide Comments, Clear Comments.
THANKS
Thanks for your attentions.
Hello and good day!
I would like to use this forum to show you my application for android and i would be very happy to get feedback and critic from you.
This is my first project and there is so much to learn – and different viewpoints are more than needed. English is not my first language so i hope that the following description is not too 'german-sounding'.
The name of my app is: x=1: Learn to solve equations! and you can find it directly at the google play store (i am not yet allowed to post links).
What is it about? (with a twinkle in one's eye)
Solving equations often causes difficulties, either in math class or later in life. At first glance they consist of cryptic characters, which are also subject to strict rules! It gets even worse: Every time we take a step to find the desired X - we have to note down the whole equation again!
But x=1 will save your day! Use it for fun, to learn or to refresh your knowledge - you can now try to find the hard to catch X without any paperwork at all! All you have to do is to connect two parts of the equation step by step - of course only if the mathematical principles allow it. Additionally, you are free to use the equal sign as you like, so you can move things from one side of the equation to the other.
In x=1 you'll be able to solve equations build with the basic arithmetic operations + -, *, /. To spice things up, the rules of bracketing are also included. 40 preset equations gradually teach you the mathematical principles - after that you'll be released into the huge world of equations to puzzle over an infinite number of randomly generated ones!
I am realy happy about your feedback and (honest- this is important) star-ratings in the Play-Store!
With mathematical regards
Daniel Gronau
First of all a big thanks to all who played, testet and contributed to x=1 with invaluable Feedback!
The first update x=1 Version 1.1 is now ready and features the first step of developement to honor your feedback.
What's new?
There are now an unlimited number of randomly generated equations! You can solve them as long as you like.
Improvements:
The calculation with fractions was simplified and you don't have to solve a big equation if you add two fractions with the same denominator or if you multiply it with 1 or 0!
With mathematical regards
Daniel Gronau
Mathematical regards!
Version 1.2 is available and improves the handling of divisions, brackes and signs. But first a big thanks to all who played x=1 and provided invaluable feedback! Thanks to you it can get more refined in every update.
Improvements:
If a bracket is expanded, the single element is now multiplied to the specific side of the participants inside the bracket. For example: (1+2)*5 -> 1*5+2*5 (to the right side) and 5*(1+2) -> 5*1+5*2 (to the left side).
Finally, no calculation will be done when adding 0 to a division.
Also a minus before a division won't be moved inside: 1-(1/2) will not turn to 1+(-1/2) but stay as 1-(1/2)!
Mathematical regards!
Version 1.3 is available and brings a new mathematical operation!
New features:
You can now reduce a division if it is simplified by the operation.
More detailed error messages added! This is only the first step. The next update will get you a detailed explanation of every mathematical operation or error.
It is now possible to use the back-button of your device to discard your last operation.
Improvements:
Some rare errors were addressed, concerning the size of some texts and the disappearance of the interaction arrow.

Thank you for posting the link! May i ask you if you tried my app? I would love to recieve feedback, this very important!
Daniel
Nice graphics and fonts! I spent so many time trying to find something like this.
Mathematical regards!
Version 1.4 has arrived and I poured my heart and soul into it, enjoy!
Improvements:
- New explanations for every action + an extended tutorial
- New design across the board (also for tablets)
- Improved the generation of the later equations
- Removed the need to sum 0 to it if you add an element to an empty side
- The biggest division-sign is now always in line with the equals-sign
Nice font and visual style! I really like stylization to blackboard.
Thank you very much! Feel free to tell me anything that can be improved!
Mathematical regards!
A small update (version 1.5) that hints strongly to the things to come!
Now you'll be able to scroll your equation around - which is very useful for large equations.
On the topic of large equations - maybe you'll be able to create one yourself in the next update?
Improvements:
- Every equation can now be scrolled around
- Performance improvements, especially for large equations
I'm working on a calculator app for android as a way to learn app development, and am looking for feedback. It's nothing fancy or exciting, but it seemed like a good place to start. The app is meant to accept an unlimited number of terms and correctly follow order of operations. When the user enters a number and hits an operation key, the number and operation are appended to the linked list. Division and multiplication are applied to their respective numbers immediately instead of being stored. When the user presses the '=' key, the app recursively steps through the list and adds/subtracts as needed, then creates a new node at the end containing the total. The whole list is then stored by another list - my intent is to add a history activity that will make previous expressions reusable. I'd greatly appreciate any and all feedback.
