Lettera is a native, refined Markdown editor for macOS. Built for writers, researchers, developers, and anyone who works with documents, from a quick blog draft to a complete technical documentation system.

Lettera works around your setup. Open a single file to read and edit it, or open a folder as your writing workspace.

Billy is a native Mac app for freelancers and small businesses who want to keep their invoicing simple, local, and under their own control.

It runs entirely offline — no accounts, no cloud sync, no third-party servers. All your data is stored in plain JSON files directly on your machine, which means you own it completely and can move, back up, or archive it however you like.

Creating and managing invoices is straightforward: Add your clients, set your line items, and style the output to match your brand. Billy gives you control over colors, fonts, and layout, so the invoices you send actually look like they came from you. When it comes to compliance, Billy meets the EU standard EN 16931 and the German XRechnung specification, and has been tested through the official KoSIT validator — so the documents you generate hold up wherever they need to.

No lock-in. No dependencies. Just an opinionated little app that helps you send beautiful, compliant invoices and stay on top of your paperwork.

• Gain insight with graphs and statistics from your workouts.

Artifacts is an image + link organizer app for macOS and iOS. A completely native, local first way to save all that stuff you find across the web. The items you save are saved locally and synced to all your devices privately using iCloud.

There is currently a free plan for up to 50 items and then a subscription to the Pro plan to unlock unlimited items. You will not be charged during the TestFlight, so don't hesitate to subscribe to test it out. We're still figuring out the exact limits and costs of the plans.

This is definitely a beta, and we have a long list of things to polish, but should be mostly stable. Please send any feedback to support@artifacts.app.

Thanks for testing!

Timefall is a journaling app I've been wanting to make for myself for a while. The idea is to have a journaling app that you write to your future self. With the app you write entries and they get delivered to you at a random time in a week, a month, or even longer. You choose a random delivery window and after you write the entry its not viewable till its delivered on the due date. On the due date you get a notification that you tap on and read the entry. The delivery process is a special way of revealing the entry to hopefully give you surprise and delight. You can share your entries if you wish with a nice share feature that creates a card like view of the entry. Timefall supports multiple journals, tags, and custom timeframes for when you will receive an entry. Hopefully this app will bring you some joy and make you even look forward to getting a notification from your phone. This is an early beta so there will probably be some bugs or rough edges to work through. Please don't hesitate to reach out and notify me. You can email me at: refactoredd@icloud.com. Thank you again for trying out Timefall hopefully it is an app that you enjoy and use regularly.
