Hello and good day!
I would like to use this forum to show you my application and i would be very happy
to get feedback and critic from you. Of course honest feedback and ratings received will be returned.

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!
Link: https://play.google.com/store/apps/details?id=com.dg.eqs


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.

Here you see a very simple example of it:
x=1.jpg

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

Hi Daniel,

The app is Wunderbar! Hehehe
I installed it here and solved some equations. Really well done. It's very polished, the tutorial explains it quite well (but maybe adding a video of an equation solving would be even better).

My suggestion to you is the app name. I think you need to modified in the app store. Otherwise it will be hard for people to find the game. No one types that in the search box.

Try something like "x=1 learn equations"
Something like that, just example. Needs to be descriptive.

Make sure to make your ASO to find the better keywords for that.

Alles Gute und viel Glück!

Hello GeoWhere!

A big thanks to you and especially for your suggestion regarding the name of the app.

This will help a lot! 

Did you find anything that can be improved and is the user interface with the arrows good to use?

Kind regards

Daniel

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

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)!

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.

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

Hi there!

Checked your app, very good by the way. Congratulations also for the effort you're doing to improve it.

My suggestions: 

-App title can be more Optimized, maybe adding something like "algebra" could help too.
-Long description is too short. Remeber that ASO for Google Play works with the keywords integrated in your description. Make it longer and find appropiate keywords. 
-I would make a promo video, cause I think is the best way to show the world what your app does. Also, keep in mind that apps/games that have a video instead of just screenshots, have a higher % of downloads. 

Regards!

A monster thanks to your for your suggestions! The app name with algebra for example, this is just way better than now. Also the thing with the description - I will definitely improve on that!

Feel free to tell me anything that might be improved.

You are awesome!

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
