Zodl: Zcash Wallet
APK
Powered by Zcash, the most private cryptocurrency ever designed, also known as encrypted Bitcoin. With Zodl, you don’t need to know how blockchains work to use private money. Zodl hides the complexity while holding the line on security, making it an easy, low-risk way to get started. Our Why We envision a world without mass financial surveillance, where law-abiding people can transact freely and privately, without fear that their data will be exploited, sold, or weaponized by criminals, corporations, or governments. A world where financial privacy is the default and access to markets is a human right. Because the ability to make transactions that sustain life and liberty should belong to everyone. There is no sovereignty without privacy. Built Different Our wallet feels simple on the surface, but is powered by engineering depth other Zcash wallets simply don’t reach. Zodl’s engineers are the original creators of Zcash, with a level of cryptography and protocol mastery unmatched by any other wallet team. Paired with the product team that set the standard for Zcash UX, Zodl innovates with a full grasp of the blockchain’s requirements, capabilities, potential, and risks. Open-Source Development Our work is open source because reliable financial privacy requires transparent development. Anyone can inspect the protocol code, audit the wallet, and verify our work. We don’t ask for trust. We show our work. Privacy by Design Unlike most apps that claim to prioritize privacy, Zodl is built for it. We go out of our way to know nothing about you. Zodl does not see, collect, or track your wallet activity, balances, transaction history, clicks, or habits. We don’t profile. Self-Custody Zodl puts you in complete control of your funds: no gatekeepers, no middlemen, just true financial sovereignty. Only you can access and manage your ZEC. Your keys, your crypto. The Most Private P2P Payments Zcash is the most private cryptocurrency ever designed, and Zodl is built by a team of developers uniquely equipped to honor that design. Shielded ZEC keeps transaction details hidden on the blockchain, and Zodl extends that protection at the wallet level. Private Cross-Chain Payments Just because your friends expose their financial data on public blockchains, doesn’t mean you should. With Zodl CrossPay, you can use shielded ZEC to make payments in whatever asset your recipient prefers, like BTC or a stablecoin. Stay private. Swaps to and from Shielded ZEC Zodl’s built-in swaps are the simplest, most privacy-preserving way to fund your Zodl wallet or move from Zcash to another cryptocurrency. User Feedback Zodl is shaped by its users. Every update reflects what our community wants most. Whether you're requesting a new feature or sharing a bug report, your voice helps make the wallet better for everyone.

dawdle
APK
dawdle is a performant and native client for the Moodle e-learning platform. This platform is oftentimes self-hosted by universities, schools and other institutions to provide teaching material to learners. Connections to arbitrary Moodle instances are supported. You may log in with username and password or, if your instance requests this, you can also sign in through a web browser (for single-sign-on). Course contents are queried from the server and stored for offline usage. Marked-up content and embedded images are usually displayed correctly. An in-app user help menu documents many of the application's features. At this moment, only some of the basic modules are supported. However, opening an unsupported module will, through magic, automatically sign you in to your browser before opening there – providing a very convenient access to all types of content. Note: dawdle can only operate if mobile web services are enabled on your Moodle instance. This is oftentimes the case, as it is also required for using the official Moodle Pty Ltd. app. Screenshot material from https://school.moodledemo.net by Mary, Chris, and Estelle Cooch licensed CC BY-SA, with adaptions.
