Adds variable speed playback functionality to audio applications, e.g. https://f-droid.org/packages/de.danoeh.antennapod.

Based on https://f-droid.org/packages/com.smithdtyler.prettygoodmusicplayer, a music player that focuses on basics, rock solid music playing, this player can be set to act as launcher. Tired of music players that take forever to start up because they're loading ads or trying to download stuff? Of music players that ignore Bluetooth controls, or stop responding after a few minutes? I was too, so I wrote this app! Feature Details: * Audiobook mode for resuming playback where you left off * Notification controls * The color theme and text size are now configurable! * This player protects against accidental pausing when your phone is jostled and the headphone cord shifts. I added this because it was annoying when my phone was in my pocket and would auto-pause because the headphone cable was bumped. * Plays .mp3, .m4p, .m4a, .aac, and many more types of audio files. * Accepts play, pause, previous, and next commands from Bluetooth headsets. * When you select 'All songs' for a given artist, the songs are ordered by album, not alphabetically. * Automatically pauses and resumes when another app (e.g. GPS) needs audio. * If another app needs audio for more than 30 seconds (e.g. a phone call), it does not automatically resume. * "Repeat All" is always on. * If you click "back" too quickly, it double checks that you want to leave before quitting.

Material You Color Previewer is a simple app that allows you to look through all Material You colors. It will also display the actual color ID, for you to easily use in your project.You can also copy the full list of Monet Colors, as they are set on your device, in the following formats: XML list for Android app development, JSON object, set of CSS variables and a C# class for Unity.Moreover, the app works on devices which run under API lower than 31 (Android 12). In such cases the app will use a fallback set of colors (blue-ish Monet theme, as the one used in apps like Google Dialer on devices running under API 30 and lower).

Compare unlimited items to find the best price! Save money in a smart way. Simply give a name (optional), enter in the cost, amount and size of each item and the unit per dollar will be calculated. This then sorts those based off best value for you to easily find the best price! Three numbers is all that is required to get an accurate answer. This app is ideal to find the best price in supermarkets but will work just in well at other stores that sell the same type of items for different prices or you can even compare prices from different stores. Features include: * No permissions! * No Ads! * 4 unit types (Weight, Volume, Length and Pieces) * Easily change the currency symbol * Summary of calculated unit/$ * Can view all items converted to one single unit * Remember data after the app is closed * Change rounding dp This app has no ads, requires no permissions, and collects no data.

PriceGrab answers one supermarket question: which of these two products is cheaper per unit?

Designed for the aisle, not for the lab • Material Design 3 with full dynamic-color theming on Android 12+ and a hand-tuned WCAG-AA palette on older devices. • Locale-aware decimal input: comma in Spanish, dot in English. No more "is the period a thousands separator?" surprises. • Inputs and result survive screen rotation and language changes. Accessibility-first • Every field has a localized content description that TalkBack reads. • The result card is a polite live region: as soon as both offers parse, the screen reader announces who wins and how much you save. • Non-color cue (a check icon) accompanies the winning offer so the design works in grayscale or for color-vision-deficient users. Privacy by design • 100% offline. The app declares no INTERNET permission. • No analytics, no tracking, no ads, no accounts. • No data ever leaves the device. Open source • MIT licensed. • Reproducible Android build, no proprietary dependencies — F-Droid friendly. • Source code: https://github.com/mablanco/pricegrab

The only way to prevent data from being abused is to prevent it from being collected in the first place. Privacy Browser has two primary goals. 1. Minimize the data that is sent to the internet. 2. Minimize the data that is stored on the device. Most browsers silently give websites massive amounts of information that allows them to track you and compromise your privacy. Websites and ad networks use technologies like JavaScript, cookies, DOM storage, user agents, and many other things to uniquely identify each user and track them between visits and across the web. In contrast, privacy sensitive features are disabled by default in Privacy Browser. If one of these technologies is required for a website to function correctly, the user may choose to turn it on for just that visit. Or, they can use domain settings to automatically turn on certain features when entering a specific website and turn them off again when leaving. Privacy Browser currently uses Android’s built-in WebView to render web pages. As such, it works best when the latest version of WebView is installed (see https://www.stoutner.com/privacy-browser/common-settings/webview/). In the 4.x series, Privacy Browser will switch to a forked version of Android’s WebView called Privacy WebView that will allow for advanced privacy features. Features: • Integrated EasyList ad blocking. • Tor Orbot proxy support. • SSL certificate pinning. • Import/export of settings and bookmarks.

Privacy Cell is a small app that displays the cell phone protocol information. At the time of this writing, many cell phone networks are switching from 4G (4th Generation) to 5G networks. The 5G network protocols were specifically designed to protect against some of the known insecurities of the older protocols, including those that allowed stingrays (IMSI catchers) to perform man-in-the-middle attacks on cell phone networks. To ease deployment and backwards compatibility, 4G and 5G networks can run together in what is known as 5G NR (New Radio) NSA (Non-Standalone) mode. This uses the 4G network for the control channel and the 5G network for the data communication. However, 5G NR NSA does not provide protection against stingrays. Android has access to all the information it needs to know if it is connected to a 5G NR NSA or a 5G NR SA (Standalone) network, but it doesn’t display that information to the user. The purpose of Privacy Cell is to make that information easy to access. Privacy Cell can also warn you when you are connected to antiquated 2G and 3G networks.
