Saber is the notes app built for handwriting. It's designed to be as simple and intuitive as possible, while still delivering unique features that you'll actually use. Additionally, Saber is available across all your devices, large and small, and syncs between them seamlessly. Notably, it can invert your notes when you're in dark mode. This allows you to write with white ink on a black background, which is much easier on the eyes in low-light environments like when the teacher turns off the lights in class. Images and PDFs are also inverted, so you can still use a digital printout or a textbook without the fuss. Saber uses a dual-password system to protect your notes from anyone but you, even if they have complete control over the server. You can safely store your notes on the official Saber server, another server, or even host your own! The app is completely open-source so that anyone can view the source code and see exactly what it's doing and how it handles your data. Many other note-taking apps are closed-source and proprietary, meaning that their inner workings are a mystery to the public. As someone who studies maths, highlighting multi-line equations was always a hassle with other apps, where the highlighter would change color when it overlapped with itself. Another problem I had was that in some apps, the highlighter would render on top of the text, fading it out and making it hard to read. Saber's highlighter has no such issues. It utilizes canvas compositing to render the highlighter in a way that is consistent with/better than traditional paper, where it handles overlaps and maintains color consistency. Saber has everything you need to keep your notes organized. Create folders inside folders inside folders to your heart's content with no limit on the number of nested folders. And even though a note may be buried deep within a nested folder, you can still access it easily with your most recent notes always available on the home screen. Discover a whole new way to capture and organize your thoughts with Saber. Whether you're a student, professional, or creative mind, Saber is your trusted companion for digital handwriting.

Proximum puts your next events where you actually look — the Home Screen, the Lock Screen, and StandBy — in a clean, customizable widget. No app to open, no clutter. Just what's coming up. It reads every calendar already on your iPhone, so iCloud, Google, Exchange and Outlook all show up together the moment you grant access. Nothing to configure, no extra sign-ins. THREE WAYS TO SEE YOUR DAY • List — a dense, glanceable agenda grouped by day • Spotlight — your next event front and center with a bold countdown • Timeline — a vertical time-spine with a live "now" marker SMART, AT A GLANCE • Automatic event icons — flights, workouts, birthdays, meetings, calls and more • A free/busy summary line: how many events today and when you're next free • A live progress bar on whatever's happening right now • Relative countdowns ("in 25m") so you always know how long you've got WIDGETS FOR EVERY SPACE • Home Screen — small, medium and large • Lock Screen — inline, rectangular and a countdown ring • StandBy — glanceable on your nightstand • A "+N more" row so a packed day never gets cut off awkwardly MAKE IT YOURS • Six hand-tuned themes, or build your own colors • Recolor every event to match the theme, add an ambient glow, or keep your calendar colors • Choose how many events, how many days ahead, and the density • Group by day; sort by time, duration or title • Font design and text size — including Easy-to-Read Times • Pick exactly which calendars appear, and mute events by keyword • Every widget can override the defaults with its own look A BEAUTIFUL IN-APP AGENDA Open Proximum for the full, scrollable version of your widget feed — the same curated events, grouped by day, with rich detail a tap away. PROXIMUM PRO — OPTIONAL, ONE-TIME Unlock once and keep it forever.

Your events are never uploaded, there are no accounts and no Proximum servers, and there is no tracking or advertising. What's on your calendar stays on your iPhone. Leave-by travel alerts are opt-in and off by default. Turn them on and your location and your event's address are used to ask Apple Maps for an ETA — exactly like asking for directions. Proximum never receives, stores or transmits that anywhere else. BUILT FOR iOS Native SwiftUI and WidgetKit, designed for iOS 17 and later. Light and dark, Dynamic Type friendly, and fast. Add Proximum to your Home Screen and always know what's next.
