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.

OneSprint: WeekFlow helps you regain focus, momentum, and clarity — one week at a time. No endless backlogs. No scattered to-dos. Just one clear goal, seven micro-steps, and a sense of progress you can actually feel. We often drown in long plans and overgrown backlogs. Planning takes more energy than doing. Weekly goals blur into noise, motivation fades, and real progress disappears. OneSprint changes that: it brings back rhythm and focus through a simple, repeatable structure — one 7-day sprint, one goal, seven steps. Start in 30 seconds. Set one weekly goal and tap “Start Sprint.” Instantly, you get a 7-day track ready to go. Each day, focus on one simple step. Edit text, check it off, add a short note, and feel the motion. The goal stays visible at the top; your seven steps form a clean, intuitive timeline. At the end of the week, write a quick retro: what worked, what blocked you, what’s next. See your growth across past sprints. Pro users can use templates to jump-start common scenarios: “Unload inbox,” “First prototype,” “Fitness restart,” “Study module,” and more. Small, fast, tangible loops beat long-term plans. OneSprint helps you move from thinking to doing without friction. Every week becomes a focused mini-journey — short enough to finish, strong enough to matter. Designed for clarity: minimal fields, instant feedback, gentle progress motion. Local and fast — no account needed. Works perfectly for solo work or small teams. Perfect for makers, founders, and creators tired of planning apps that feel like spreadsheets. For students and professionals who want to see progress every week. For anyone building habits of focus, reflection, and momentum. OneSprint: WeekFlow follows a simple philosophy — one focus, one week, one real outcome. No distractions, no noise, just consistent flow. Start your first sprint today. One goal, seven days, real progress.
