Billy – Invoice Manager

Join

In Catalog

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.

Artifacts: Images + Bookmarks

Join

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: Journal App

Join

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.

Intro: Contacts + Notes CRM

Remember people, names & faces

• You can now export all your data, either as a readable Markdown bundle or as a full-fidelity .introarchive backup that can be re-imported into the app without losing any detail. • A sync-status banner now indicates when iCloud is syncing, so it's clear when changes are still being uploaded or downloaded across devices. • A person's photo now appears on their card as soon as that person syncs from iCloud, instead of waiting for the heavier photo records to finish arriving. • The People list now loads dramatically faster on large libraries, including those with many photos. • Person photos and avatars now load in the background rather than on the main thread, so lists and the timeline scroll smoothly while images appear.

SSH Client - Secure ShellFish

Terminal, Files & Finder

New manual page viewer. Select a command in the terminal and choose Manual to read its man page without leaving the app, or browse all of a server's manual pages from the View menu. Pages are downloaded and rendered on device, so they are searchable and selectable, with a section navigator and tappable cross references like fork(2) that jump to the referenced page. Fixed the paste button in the keyboard bar sometimes appearing blank. As a result, iOS may now prompt you when pasting from other apps. You can turn these prompts off under Settings → ShellFish → Paste from Other Apps → Allow. Type Sentence mode no longer ends when you press enter. You can still toggle from the paste button's context menu. Open Terminal action now works correctly on iPhone. When creating Digital Ocean droplets, plans are now correctly sorted by price. Improved importing of iTerm2 terminal themes.

Sunset Predictions: Alpenglow

Sunrise & Golden Hour Times

A few bug fixes for the 10th anniversary release. This update celebrates Alpenglow’s 10th anniversary with one of the biggest releases in the app’s history. A NEW ALPENGLOW FORECAST MODEL • For the first time, Alpenglow’s forecasts are powered by its own proprietary model. • This means more reliable predictions, faster improvements, and the freedom to build features that weren’t possible before. This is a huge step for the app and lays the foundation for where Alpenglow goes next. INTERACTIVE FORECAST MAPS • Explore sunrise and sunset predictions directly on the map. • Pan around your region, zoom in on areas you care about, and quickly see where conditions look best. Whether you’re planning something local or chasing light further afield, this makes it much easier. • Available with Alpenglow Pro. FORECAST MAP WIDGETS • Forecast maps now come to your Home Screen. • The new map widgets show forecasts over your location with customizable zoom levels, so you can choose the view that works best for you. • Available with Alpenglow Pro. 7-DAY EXTENDED FORECASTS • Plan further ahead with forecasts up to a full week in advance. • Perfect for scouting shoots, planning trips, or just keeping an eye on the sky. A REDESIGNED MAP EXPERIENCE • The map experience has been reworked across the app. • Smoother controls, a cleaner interface, and easier switching between forecast and sun direction modes make it more powerful and more enjoyable to use. SUN ALIGNMENT IN AR • One of my favorite additions. • Point your phone at any spot between the sun paths in AR, and Alpenglow will tell you the date and time the sun aligns with that position. A whole new way to scout compositions and plan ahead. MORE IMPROVEMENTS • Current location widgets now update automatically as you travel • Widgets can rise in Smart Stacks as sunrise or sunset approaches • Yearly variation shown in Times view • Customizable times including Astronomical and Nautical • Option to disable elevation-adjusted times • Spotlight support for saved locations • Interactive Live Activities with Lock Screen actions • Dynamic Type improvements • General performance improvements and bug fixes THANK YOU Ten years ago, Alpenglow was a much smaller idea. This update brings in features I’ve wanted from the very beginning, and it feels especially meaningful to ship them as part of the 10th anniversary. Thank you to everyone who has downloaded the app, shared it, supported it, sent feedback, and helped keep it growing over the years. I really hope you enjoy this one.
