Plexus
APK
Remove the fear of app compatibility on de-Googled Android devices. Google Play Services are essential components on most Android devices. They allow you to access your Google account seamlessly and provide Google-specific features for apps that depend on them. However, when you flash custom ROMs without Google Play Services or opt for alternatives like microG, certain apps may encounter issues — either not functioning at all or experiencing limitations in specific features. Plexus provides detailed insights into app compatibility whether you’re using ROMs without Google Play Services (like LineageOS) or ROMs with microG (such as CalyxOS). It helps you identify which apps work, don’t work or have limited features. All the information is crowdsourced by the community, for the community.

Plug Off Airplane
APK
This is a very simple app that turns off Airplane Mode when the USB cable is plugged in. The idea is to make sure Airplane Mode is turned off at least once a day, in a safe location in terms of metadata: the home. Your telecom already knows your device belongs to its billing address. This makes it easier to use Airplane Mode to disable the cellular radio during the day, when it is not needed.

PlusMinusTimesDivide
APK
A program to train children's mathematical skills in the four calculation methods: addition, subtraction, multiplication and division. The preferences allow to adapt the difficulty to any pupil's level, from basic primary (elementary) school to secondary and beyond. Possible changes include: * maximum of operands or result, * integer or decimal (with up to four decimal places) operations, * with or without carry over, * multiplication and addition tables training, * number of authorized tries, * and some few others... The program also gives hints when the given answer is wrong (send your tips to the author, if you have some more!). For advanced users, there is a timer -- but it is shut-off by default, as to not stress sensible children. The challenge mode (reachable from the menu in the first dialog) allows children to play against themselves and others with predefined challenges and a high-scores list. Finally, the language of the app can be set differently (English, French, German, Italian, Spanish) from the system default.

Plutus - Investment Tracker
APK
Plutus will help you to track all your investments in one place. We're not portfolio tracker, we won't show you daily ups and downs. We help you keep track of money moving out of your account into different types of investment. This app is not a budget management tool, we're not here to manage your day to day spending. This application is here to track all the investment you make. So for example you have invested money in stocks, etfs, bonds, retirement fund, high yield savings account, Fixed deposits, gold bar in your locker or just some money in your savings account. This app will allow you to list all this investments and categorize it for you into different categories/sector of investment. This application will allow you to record what type of application/service you used to invest your money (For example you use couple of brokers to manage your stock portfolio, this application will allow you to list through which website/app had you invested your money. So when you open this app, it should be easier for you to notice which app to check for particular investment) And best part is it will calculate the amount invested in each category and show you a graph showing percentage of investment done in all various categories. So consider this application as your one step way to see all the money that you invest in all the places. Ofcourse you can do all this using Microsoft Excel as well. But we're not competing with Excel. We're here to give you an alternative way to check your finances. If you prefer to use excel, use that. But make sure your excel file is password protected and with you at all times. Because this application has fingerprint authentication and is installed on your phone on all times. So you just need to take out your phone and will be able to check your investments. (I personally don't like using excel sheet and haven't seen any of my friends commit themselve to use excel sheet to manage their finances for long time. That's the reason I decided to create this application, and as there is an alternative with excel I decided to make it opensource and free. So if you don't like excel to manage your finances, you can jump on to this application.) I've also created a widget for this application. So you can just glimpse over your total invested amount on the homescreen itself. Yeah it's not safe to show this amount on the homescreen but I developed this feature just in case, any of us need any push to continue their job/business. Seeing that total invested amount on the home screen can motivate you to just give that little extra. If you don't feel it's safe to show the amount there, don't use the widget. But I gave that option just in case anyone wants to use it. And you can even place this widget on the different homescreen. So unless you swipe to it, no body else will even know it's there. Once you've added your investment data, you can share the data you inserted using Export data option in settings tab. You'll be able to share your data as an excel file. Just to be clear, this application is not a portfolio tracker. There are plenty of applications that do that already. We're here to track money going out of your bank account into different type of investment. Consider it an easy way to check how much money you've invested over the years and where. Plutus doesn't use internet connection, so you can be sure that data you insert in this application is not shared with anyone (unless you share it from the settings menu). It's just for you to see. So you can be sure that we can't track your investment data, nor can we sell anything to anyone.

Poleidoscope
APK
Did you ever wonder what the world looks like through a holomorphic function? No? Wondering what a 'holomorphic function' is in the first place? Don't worry! You don't need to know any of this to use the app. Just touch the screen and see the math at work! The Poleidoscope shows a rectangular domain of the plane of complex numbers. The user sets up roots and poles of a rational function on the screen and this function is then used to deflect the live camera picture. Holomorphic functions are examples of so-called 'conformal mappings' which are prominently featured in the works of contemporary artists such as M.C. Escher. The Poleidoscope provides a live experience of similar pictures. For those more involved in mathematics the app is a way to visualize complex polynomials and rational functions and give a feeling for several topics in complex analysis such as differentials of holomorphic functions, Rouche's theorem, ramifications, local normal forms, etc.
