Bitcoin Address Checker (BitAC) is an open-source application designed to be lightweight and fast. The idea is to provide to Android users an easy and quick way to check the balance of bitcoin addresses. This application does not prove and is not intended to provide any functionality of a bitcoin wallet, so you can not receive, send or save bitcoins with BitAC, you can only check how many bitcoins a wallet has.

Bitwarden is the easiest and safest way to store all of your logins and passwords while conveniently keeping them synced between all of your devices. Password theft is a serious problem. The websites and apps that you use are under attack every day. Security breaches occur and your passwords are stolen. When you reuse the same passwords across apps and websites hackers can easily access your email, bank, and other important accounts. Security experts recommend that you use a different, randomly generated password for every account that you create. But how do you manage all those passwords? Bitwarden makes it easy for you to create, store, and access your passwords. Bitwarden stores all of your logins in an encrypted vault that syncs across all of your devices. Since it's fully encrypted before it ever leaves your device, only you have access to your data. Not even the team at Bitwarden can read your data, even if we wanted to. Your data is sealed with AES-256 bit encryption, salted hashing, and PBKDF2 SHA-256. Bitwarden is focused on open source software. The source code for Bitwarden is hosted on GitHub and everyone is free to review, audit, and contribute to the Bitwarden codebase.

BlitzMail is an Android app that allows you to set up your email account once and then use it to send emails or short notes to an address of your choice. This comes in handy when you need to send a lot of things via email, because you are in a low connectivity area (e.g. subway) and want to remember things to look at later. It also works when you are offline. BlitzMail then queues your emails and allows you to send them later when you have connectivity again. The SMTP password is stored encrypted with a built-in key and salted with your device ID. This is not fully secure, but should provide reasonable protection for your password.

Simple to use map based application, visualizing real time full area lightning data provided by the blitzortung.org lightning location network project. The current thunderstorm situation at your fingertips. Features: * realtime display of lightning data * display of historical lightning data of the last 24 hours * for regions Europe, North & South America, Asia, Africa and Australia/New Zealand * lightning strike time color coded * reduced data volume and fast response * current lightning strike time and lightning count * optional user location marker * alert function shows distance/direction of storms * background service for alerts * support for notifications, sound and vibration alarm * single stroke display for blitzortung.org participants Please visit https://www.blitzortung.org for more information regarding the community based lightning location project. The raster display ensures a fast performance of the application even if there is a very high thunderstorm activity. Blitzortung.org participants can visualize all stroke locations individually. If you would like to contribute to a translation of the software in your language, please do not hesitate to contact the author of the software. User privacy This app can use device location in order to show the users location on the map and for generating warning view and alerts for lightning activity nearby. The lightning warning feature **can also be used without device location permissions** as the location can also be set manually (via preferences but also via long pressing the desired position on the map). You will still be able to use the warning feature without allowing location permissions. In order to have a more efficient data transfer with high resolution lightning data the app only fetches the last 10 minutes of activity in an area of 5° x 5° rounded to five degrees. Although this data is derived from the devices location or the map area currently visible it can not be used to track users. Here is why: Granularity: A 5x5 degree area is extremely large. Latitude: 5 degrees covers approximately 555 km (345 miles). Longitude: At the equator, 5 degrees is also ~555 km. At 50° latitude (e.g., Central Europe/Canada), it is still ~355 km wide. This resolution is sufficient to identify a broad region (e.g., "Central Europe" or "US West Coast") but is completely insufficient to pinpoint a city, let alone a specific person or address. Anonymization: The calculation `(coordinate / scale).toInt()` effectively quantizes the location. All users within that massive 5x5 degree square report the exact same grid index (e.g., x=2, y=10). It is impossible to distinguish between two users within that same ~300,000 km² area based solely on these coordinates. On top of that, there is no data provided which would allow to link subsequent requests coming from the same app. Conclusion: The coordinates generated by `LocalData.update()` are too coarse for individual tracking. They serve only to download lightning data for the correct general region of the world.

Block Puzzle is an addicting classic game! A little pastime that is not about speed. With new multi-player mode "Stone Wars"! Different game pieces are to be inserted in a 10 x 10 large playing field. Horizontal rows or vertical columns are removed as soon as they are full. As the game progresses, more tile shapes are added again and again. Game pieces can be rotated by tapping. What high score will you achieve? Parking: A game piece can be parked in the gray field. But be careful! As soon as no more pieces can be inserted in the playing field or in the parking area, the game is over! So play the parked game piece as quickly as possible! Rotate the game piece by tapping it. Gravitation: If horizontal rows are cleared in the lower playing field, the upper part slides down. Points system: - Insert: number of blocks on the piece - Clear row: 10 points - clear away several rows at once: bonus points - The playing field has only 1 block left or is empty: extra bonus! After that the playing field must be filled 40%. - 20 connected pieces of one color result in a further extra bonus. - Star block gives 200 bonus points! Block Puzzle Stone Wars While the old game (with randomly generated game pieces) has been retained, a new multi-player mode has been added: Stone Wars. You are on a spaceship and you have to liberate the galaxy. In the distant future, conflicts will be resolved by playing Block Puzzle. Navigate through a star cluster of tens of planets at lightning speed thanks to the spur drive. Little by little, the space map is revealed. The planets are of different sizes and have different gravity, which affects the game. The liberation takes place through the Block Puzzle Classic Game or through the new Cleaner Game. In the Cleaner Game, you win by clearing the playing field. However, if your enemy needs fewer moves, he is the liberator of the planet. In the Classic Game, however, a high score counts. A minimum liberation score (MLS) must be achieved in the Classic Game. In some cleaner games, a certain number of moves may not be exceeded (XLM). Since the epochal data breach 200 years ago, a data processing system is no longer allowed to send or receive data. Therefore, you have to exchange your score with your friends or enemies via another app (e.g. WhatsApp). Enter your player name, which is as unique as possible, and copy the score of the current quadrant in the data exchange. Then go to WhatsApp, for example, and add the game status there. The recipient can then copy this saved game and paste it into the Stone Wars data exchange. You then take over all planets in his game where you are better than him. Will he be able to drive you out again? Stone Wars works in such a way that you first select a planet in the navigation and click Select. Then tap back on the phone and start the liberation. All game pieces are predefined in terms of type and order. Our program is and will remain free and ad-free. There will be no in-app purchases. It does not require any phone rights and is played completely offline.
