SuperFreezZ: App stopper
APK
Android app making it possible to entirely freeze all background activities of any app. A note to everyone who was supporting SuperFreezZ over the years: SuperFreezZ was my first "real" programming project, and I was incredibly happy about strangers donating to me and translating the app into languages I never heard of, and all the positive feedback I received. My start into the world of free and open source software couldn't have been better. It is hard to imagine now that back in 2018, when I made my first commit, I barely knew how to program at all. I didn't know where to start, so I just forked an app called "APK Extractor", and started finding out. I learned how to organize a (small) codebase, how to interact with a small-but-supportive community, and how to stay focused when there are lots of nice features that could be implemented. But the time has come to slowly wind down SuperFreezZ. These days, Android devices make it harder and harder for an app like SuperFreezZ to work properly. Also, Android devices are anyways restricting the amount of time an app is allowed to run in the background, making an app like SuperFreezZ less essential (without giving the user control over it, though). Myself, I am mostly busy working on other projects these days (mainly "Delta Chat" and "Chatmail"). It's not over yet, though! If you have an old and slow phone, or if you like that SuperFreezZ gives you control over which app runs and which does not, then enjoy. And who knows, maybe one day, I will revisit this first project of mine, adding more of the features that were asked for over the years, or maybe someone will fork it. If SuperFreezZ does not work for you, here are a few alternatives I found on F-Droid (though I can't personally vouch for them): "Force Stop Helper": Similar to SuperFreezZ, with less features but still maintained, and you need to press "Force Stop" by yourself "Drowser": Uses Root to prevent apps from running in the background "Shelter": Allows you to isolate apps (and optionally to keep them from running in the background), but requires some extra storage to work Thanks again for being part of this! If you want to try out SuperFreezZ, here you go: SuperFreezZ Get back control over what runs on your phone Enhance battery life and reduce mobile data usage by freezing rarely used apps Especially useful while you are on a tour, where you need only some apps but a long battery life Greenify can also do this, but it is not Open Source. SuperFreezZ is not yet another task manager promising to delete 10 GB of data per month or making your device 2x as fast. This is impossible. Instead, SuperFreezZ is honest about its disadvantages: Freezing daily used apps probably drains your battery a little faster. Also, these apps will take longer to start when you use them the next time: SuperFreezZ will super freeze your apps, it takes about 1-3 seconds to un-freeze them. Greenify has the same disadvantages, except that the author of Greenify does not warn you about it. So: Just do not overdo it, and SuperFreezZ will be super useful. Examples for apps that deserve to be frozen: Untrusted apps (that you do not want to run in the background) Apps you rarely use Annoying apps Features Optionally works without accessibility service as this slows down the device Can freeze only apps not used for a week (can be configured) Choose a white list (freeze all by standard) or a black list (do not freeze anything by standard) Can freeze apps when the screen goes off Options to freeze system apps and even SuperFreezZ itself Completely open source and free software

SuperShopaholic
APK
SuperShopaholic is a tiny game that is really a sociopolitical statement about the pointlessness of consumerism. You steer an infinite shopping cart through an infinite mall, frantically swooping goods off the shelves into a cart that never fills. There is no finish line. There never was. The "rewards" are the joke: you grind to unlock the ability to consume faster, and the prizes are absurd status symbols that, once bought, change nothing. Mechanics: * Grab everything. Emoji products fall down the mall; catch them for cash. * Power-ups are the fantasy. Grab a GOLD card or a rarer BLACK card to shop faster with a 2x / 4x money multiplier. The reward for consuming is the ability to consume harder. * Status symbols. Periodic BUY NOW events offer a Ferrari, Yacht, Mansion or Private Jet. Buy it and it joins your trophy shelf, and then absolutely nothing changes. You keep shopping. * A STATUS meter fills up and, as the game helpfully notes, it doesn't do anything. * No win state. The speed only ever increases. Controls: tap or drag to move the cart. A hardware keyboard works too (left/right or A/D, P to pause). Technical notes: * Fully offline. The app requests no permissions and makes no network connections. The whole game is a single self-contained HTML page bundled in the app and rendered in a WebView (HTML5 canvas, vanilla JavaScript, Web Audio for synthesized sound effects; no audio assets, no tracking, no ads). This game critiques the enclosure of things; its license resists the enclosure of itself. SuperShopaholic is free software under the GNU Affero General Public License v3.0 (AGPL-3.0-or-later). The AGPL's network clause means anyone who hosts a modified version must also share their source with players. Source is always one click away: https://gitlab.com/jave/supershopaholic

Swatch .beat clock
APK
Are you tired of the boring old 24-hour format? Could you use some change in your life? Let me introduce you to the Swatch Internet Time format! Instead of dividing the day into 24 hours, it divides it into 1000 .beat's. 6:00 AM becomes "@250", 11:27 PM becomes "@977" and so on! In addition to that, there are no timezones in Internet Time. It's the same all over the world. It's based on Biel Mean Time (BMT), similar to Central European Time (CET). Of course, getting used to this new format might not be easy, and even when you learn it, you will still need a .beat clock. That's where the Swatch .beat clock app comes into place. With a handy converter and a fully functional digital clock, it will help you through your journey. Read more about Internet Time on Wikipedia.

Sweet IPFS
APK
Sweet IPFS is forked from https://f-droid.org/packages/org.ligi.ipfsdroid, which was experimental. This app is currently in beta stage, not all features are implemented, but the most important is. Feel free to test it and review it. If you find a bug or have problems with this app, you can contact me with the email provided on the GitHub page. Sweet IPFS targets end-users and developers in order to make IPFS (and decentralization) an everyday standard. Its main goal is to be used as a file sharing app. For that, it provides a file chooser, QR codes, and a browser. To go even faster, you can upload a file or a text directly from any app by simply sharing it and choosing Sweet IPFS. At the current point, battery and network usage depends a lot on your phone and your Android version, and may be high. I am working on this in order to provide the best experience and an everyday usage.
