Kase exists because it should. There should be a database app that can go anywhere with you. It should be: • Simple — Using it should be easy and intuitive, • Flexible — Once familiar with the basics, you can design any database to track anything important to you, and • Relational — Inter-linked data is an order of magnitude more useful. Plus, you don't want to repeat yourself. Additionally, it should be: • Personal — You should not need to worry about who can peek into your data, and • Always Available — High-speed wireless network should *not* be a prerequisite for accessing your own data. Structured data at your fingertips. Something like that didn't exist, so I started creating Kase in 2014. Basic Concepts: • Your Kase contains Boxes. • Each Box stores Decks that can relate to each other. • A Deck collects similarly structured Cards. • And a Card is where you put data Entries. Features: • Pick, assign, and organize with Categories, Tags, and Marks. • Search by name, notes, full text, or keywords: Full-text indexing with Natural Language Processing. • Highlight any Box, Deck, Card, Entry, or Keyword. • Deck definitions support inheritance! • Field types include Text, Number (with Unit), Money (with Currency), Date/Time (with Time Zone), Choice, Boolean, Link, Picture, and Document. - complete with multi-level auto-conversion • Write in Markdown and see rich formatted text. • Box can be locked with a passcode, and unlocked with Face ID or Touch ID. • Formatters (Fx) to visualize data in different ways without altering the data one bit. e.g. Unit Converter, NameMapper, WordScrambler, ICU Transformers... • Side-by-Side: Compare Cards easily by displaying in columns. • On-device Text Recognitions (OCR) for multiple languages. • Import/Export in CSV, JSON, or KASE. • Complete Backup & Restore. • iPad Multitasking support: Split View, Slide Over, etc. • Very customizable UI with custom locales What Kase Can't Do: - Cloud sync is not done yet (stay tuned...) What Kase Can Do: > From Data to Wisdom > Data ▹ Information ▹ Knowledge ▹ Wisdom 1. Store Data — the objective truths. 2. Organize Information — to reflect circumstances and current condition. 3. Systematically retrieve Knowledge — utilized for decision-making. 4. And that hopefully enables you to grasp Wisdom, comprehend insights, and ultimately create value. There are databases that belong to the Big Guys. The rest of them should stay personal. By now, you should realize how valuable your data is. So why give it away? Kase keeps your data yours.

About

VisibleHour

Features
Read full description

An always-visible view of time on your phone, your wrist, and your spatial workspace. The day, drained as it passes. Your session, draining as you work. A quiet tap on your wrist when you've been at something too long. For when 30 minutes feels like 5. VisibleHour is a single-purpose external time sense — designed for people whose internal clock isn't always reliable. For time blindness. For hyperfocus. For the moments when "just five more minutes" becomes an hour. The dial isn't a clock face you check. It's a clock face you live alongside, on every surface you already glance at. Three rhythms, on every screen. The day. Your waking hours rendered as a draining amber arc — from the moment you start your day until you wind it down. Tells you how much day is in front of you, not just what time it is right now. The session. A focused block — 15, 25/5 Pomodoro, 30, 60, or 90 minutes. The pie at the center drains as time passes — a visual timer at session scale. Tap it to zoom into a visual timer face with minute marks. Pomodoro mode shows two amber tones — work, then a softer break. The body. A quiet tap on the wrist at the interval you set — 60, 90, or 120 minutes. No banner. No streak. No "you've been at this for two hours" guilt. Just a tap that says: notice the time. Optional desk mode — keep your phone or iPad awake during a session so the dial stays visible while you work. Cross-device sync. Start a session on your Vision Pro while working in spatial. Within a second, the Live Activity appears on your iPhone Lock Screen and the dial fills on your Apple Watch. Stop on the Watch — every screen clears together. Powered by iCloud private database, with no telemetry leaving your device. Calendar-aware. Optionally show your day's events on the dial — a quiet ink line for each meeting, sitting alongside your session. Tap the dial to surface the next event's title. Widgets everywhere. Lock Screen and Home Screen widgets on iPhone. Native complications on Apple Watch in four families. A spatial widget on Apple Vision Pro that coexists with your email, your MacBook display, and whatever else is in your spatial workspace. What it isn't. This is not a habit tracker. Not a productivity hammer. Not a notification machine. There are no streaks, no leaderboards, no "you used the app 12 days in a row" celebrations. There's no analytics, no third-party SDKs, no ads. The whole product is one quiet answer to a quiet question — how much time has passed? Privacy. No tracking. No analytics. No third-party services. The only data that ever leaves your device is the small piece of state that syncs through your private iCloud (active session, day boundaries, awareness interval, appearance preference). Calendar events are read locally on each device — they never sync to the cloud. Made quietly by sthreelabs.
