Open FNDDS Viewer
APK
This project is designed to take the data from the USDA's Food and Nutrition Database for Dietary Studies (available here: (https://fdc.nal.usda.gov/download-datasets.html) and present it in a way that people can easily access, since right now the way that it is structured and formatted makes getting any information an extremely tedious and time-consuming task. In addition to displaying the data, it also includes some more handy features including: * Searching for food items * Adding foods to a list of favorites for quick access * Comparing information about different food items * Showing more detailed info about nutrient densities, macronutrient percentages, etc. * Fully offline and privacy-friendly, no permissions needed whatsoever!

Open Link With...
APK
Share the current web page when you are in a browser to open with another app! Did it ever happen to you? You click a link (let's say a video link) and the system does not ask you anything and opens the link in the browser. And you are stuck in a web page instead of watching the video in the native app. There are 2 options for you. You either watch the video in the web or you remember the name of the video and search it in the app. Well, not anymore. With OpenLinkWith, you can share any webpage with it and it will ask you which applications to open the link with. Although the original intent of the application is to direct web pages to apps, it can even be used to switch between apps. Imagine you have 2 Twitter clients in your phone. You can open a tweet in the official Twitter application and then switch to an another app with the same tweet opened. Cool, hah? Although the problem discovered above is not huge, it is missing in the Android ecosystem. And I couldn't find anything doing this. So I wrote one. :) If you find yourself sharing the same url over and over, you can use "Add to Home Screen" feature to add your favorite link from your favorite app to your home screen. I hope you find this useful. Please help me by trying it and sending feedback to me. Note:

Open TimeLimit
APK
This App (Open TimeLimit) is mostly equal to TimeLimit without the linking of multiple devices. Flexible Apps are grouped to categories (a category can contain one or multiple App). You can chose per category at which times it should be allowed. This allows preventing playing games too late. Additionally, you can configure time limit rules. These rules limit the total usage duration at one day or over multiple days (e.g. a weekend). It is possible to combine both, e.g. 2 hours per week end day, but in total only 3 hours. Moreover, there is the possibility to set an extra time. This allows using something longer than regulary once. This can be used as bonus. There is additionally the option to disable all time limits temporarily (e.g. for the whole day or an hour). Multi user support There is the scenario that one device is used by exactly one user. However, with tablets, there are often multiple possible users. Due to that, it is possible to create multiple user profiles in TimeLimit. Each user has got different settings and time counters. There are two kinds of users: parents and children. If a parent was chosen as user, then there are no restrictions. Parents can chose any other user as current user. Notes It can be a good idea to take a look at https://timelimit.io/en/configsuggestions/ if you don't use TimeLimit in the default scenario. TimeLimit does not work good at some smartphone brands (mostly Huawei and Wiko). With the correct settings, it can work better. But better is not good. If it "does not work": This can be caused by power saving features. You can find at https://dontkillmyapp.com/ how you can disable these features. Get in touch with the support if that does not help. Depending on the Android version, TimeLimit uses the permission for the usage stats access or the GET_TASKS permission. These are only used to detect the currently used App. Based on the currently used App, the App is blocked, allowed, or the remaining time is calculated. The device admin permission is used to detect an uninstallation of TimeLimit. TimeLimit uses the notification access to block notifications of blocked apps and to count and block background playback. Notifications and their contents are not saved. TimeLimit uses an accessibility service to press the home button before showing the lock screen. This fixes blocking in some cases. Moreover, this allows opening the lockscreen at newer Android versions. TimeLimit uses the permission "draw over other Apps" to allow opening the lockscreen at newer android versions and to overlay blocked Apps until the lockscreen is launched. TimeLimit uses the location access to detect the used WiFi network and allow/ block Apps depending on it and your settings. The location access is not used otherwise.
