Discover aircraft around you with OGN AR Viewer, an experimental privacy-friendly augmented reality client to the OGN (Open Glider Network). Keep a private directory of the aircraft that belong to your club or friends and see how far they are. For free and without advertisements. Privacy note: the application needs to send your location to the OGN in order to listen for aircraft beacons around you and because the OGN doesn’t support encryption, this happens in clear text. The good news is that OGN AR Viewer reduces the location accuracy to about 5 km before transmitting it and then restores it back on recipient, so the fine location never leaves your device. It further anonymizes you by connecting to the OGN without identification (other clients based on the official library generate an identifier based on your hostname). Check out the privacy policy to learn more (it is written in simple language and has illustrations).

Having the right meme or sound at the right time can make a joke work! Sounds are so much fun and this is why you need to download OMGSoundboard. OMGSoundboard allows you to create your own unique soundboards. What's exciting about this app is that it allows you to be only limited by your imagination. You are free to use whatever sounds you want because it is possible to import sounds you love. A backup is also integrated of course so that you can keep your collection forever. The software is simple and straightforward to use. You can also layer the sounds by adding effects and playing several sound effects at once. OMGSoundboard works offline, offers a good search function, and the ability to set sounds as ringtones and/or alarms. Please note that OMGSoundboard has just a very limited amount of sounds available by default because of copyright reasons. The following are some of the app's main features: * You have the option of making as many soundboards as you want. * Your personal tunes can be imported * You have complete control over when the sound starts and stops. * Sounds can be played back at the same time, allowing you to layer them if desired. * OMGSoundboard will back up your sounds so they don't get lost. * All apps that allow sharing can be used to share the sounds. (Bluetooh, Wifi, NFC, Social Networks, and so on.) * You get to select Ringtone, Alarm, and Notification sounds. * You can save your favorite sounds as bookmarks. * Allows for word-filtering for a more useful and fast search inside a large number of sounds. * Supports Wear OS by Google smartwatches. * No ads and no trackers.

Are websites and social media apps blocked? Is your network unusually slow? Run OONI Probe to find out! With this app, you will examine the blocking of websites and instant messaging apps, measure your network's speed and performance, and check whether systems that could be responsible for censorship and surveillance are in your network. OONI Probe is developed by the Open Observatory of Network Interference (OONI), a free software project (under The Tor Project) that aims to uncover internet censorship around the world. Since 2012, OONI’s global community has collected millions of network measurements from more than 200 countries, shedding light on multiple cases of network interference. ▶ Collect evidence of internet censorship You can check whether and how websites and instant messaging apps are blocked. The network measurement data you will collect may serve as evidence of internet censorship. ▶ Detect systems responsible for censorship and surveillance OONI Probe tests are also designed to uncover the presence of systems (middleboxes) that could be responsible for censorship and surveillance. ▶ Measure the speed and performance of your network You can measure the speed and performance of your network by running OONI's implementation of the Network Diagnostic Test (NDT). You can also measure video streaming performance with the Dynamic Adaptive Streaming over HTTP (DASH) test. ▶ Open data OONI publishes network measurement data because open data allows third parties to verify OONI findings, conduct independent studies, and answer other research questions. Openly publishing OONI data also helps increase transparency of internet censorship around the world. You can explore and download OONI data here: https://ooni.io/data/ ▶ Free software All OONI Probe tests (including our NDT and DASH implementations), are based on free and open source software. You can find OONI software projects on GitHub: https://github.com/ooni. Curious to learn how OONI Probe tests work?
