Hello, I’ve been working on a native macOS client for Mastodon called Oliphaunt, built primarily with AppKit and some SwiftUI integration. It’s designed to feel fast, lightweight and truly native — not a web wrapper, Catalyst, SwiftUI, or Electron app. I’d appreciate any feedback from fellow developers and testers. Key features: Native UI using AppKit (with some SwiftUI) Core Data for local caching Responsive, keyboard-friendly interface UX tailored for macOS (desktop-class usage) Supports multiple accounts, cross-instance timelines and search The app supports macOS 14 Sonoma and later. Feedback is welcome via TestFlight, on GitHub, or right here. Thanks in advance to anyone who gives it a try!

Budget Budgie is a straightforward budgeting app for anyone who gets overwhelmed by budgeting! Most people who don’t budget their expenditures don’t know where to begin. Linking bank accounts, debit accounts, credit cards can be scary. Too many graphs and charts is distracting. AI integration is confusing. This all adds up to people giving up before they begin. Check out the first public build of Budget Budgie and please provide feedback as described in the TestFlight. Thanks!

Solarday is a calm, intention-based app I designed to help myself be mindfully productive – to focus on what matters without drowning in endless checklists. After years of trying productivity tools that made me feel busier, not better, I wanted to build something that encouraged focus, intentionality and balance.

Hi everyone! I’m looking for beta testers for Rapp, an iOS app designed to help you figure out what you can cook with what you already have at home. Key features: Shopping items you check off automatically move to a Home list Recipe suggestions based on your available ingredients Browse a collection of recipes and save your favourites Import recipes from the web using a built-in browser Add items by typing, dictating whole lists, or scanning your fridge with your camera Other cool features: Automatic icon generation for shopping list items Ingredient wiki – tap any ingredient to learn more The goal is fewer food decisions, less waste, and faster everyday cooking (hence the name: Rapp = quick in Swedish).

"Day of Delivery" is used to check deliveries from IKEA. When the carrier brings you a pile of boxes with the disassembled furniture for your home, you can easily check that everything is correct and resolve any problems immediately. This avoids stress and unnecessary costs if you discover a mistake during assembly. What to test?
 The app uses data from PDF receipts that IKEA sends by email. Although receipts from different countries are similar, it is necessary to make adjustments for each country. That is why I need to test as many receipts from as many countries as possible. If the app encounters a problem with receipt compatibility, it will offer to send me the receipt for analysis to improve compatibility. Thank you in advance. Michal Kus
