Read full descriptionHide full description
masterfile is five everyday tools in one quiet place. Scratch, Vault, Budget, Notes+, and Kanban. Built for people who'd rather think than juggle apps and for those ready to start tracking. โ Scratch โ Type anything. As you write, a chip appears suggesting where the line belongs, tap it to promote. Credentials go to Vault, money goes to Budget, ideas go to Notes+, tasks go to Kanban. One note keeps your mind clear, the modules keep your day organized. โ Vault โ Logins, cards, and credential keys, locked behind your device's authentication and stored only on your device. No account, no sync, no tracking. Real device-level encryption underneath as masterfile just makes it pleasant to use. โ Budget โ Multi-currency budgeting that actually understands how Filipinos, especially freelancers and remote workers earn. โฑ, $, ยฅ, โฌ, and 20+ more currencies tracked in parallel. Net worth stacked by currency, category-level budgets, calendar view, and a calm pie chart of where the month went. โ Notes+ โ Plain notes for the quick stuff, rich notes when you need them. Folders, tags, internal linking, checklists, bookmarks, document-scanning, camera, attachments. Reading mode opens each note like a printed page you set yourself. Highlights, links, and headings all preserved where you put them. โ Kanban โ Every project, sorted into columns. Priority flags, due dates, color labels, archived cards, and an aging indicator that quietly tells you which cards have been waiting too long. โ Widgets, Notifications, the rest โ 19 home-screen widgets across all five modules. Credit card due dates, budget thresholds, friendly nudges. Soft prompts to keep you tracking, organizing, and checking in. Every alert opt-in, every one off by default. โ How masterfile stays calm โ No account. No tracking. No ads. masterfile lives on your device, owned by you. One purchase unlocks every module, every widget, every alert. Yours forever, no subscription, no renewal. Launch special โ one-time unlock at the launch price, until July 31. Regular pricing returns on August 1.

The problem with to-do apps? You have to open them. Islet keeps today's tasks on your Dynamic Island and Lock Screen. One task always stays on screen, done with a single tap. How it works - Tap "Start Session" to pin today's tasks to the island - Long-press the island to browse and complete right there - view and action in one place, even when the app is closed - On the Lock Screen, a larger card with one-handed button layout - Overdue tasks are marked orange and shown first - Jot memos straight from the island - Lock Screen widgets and controls to start a session or add a task in one tap Store it your way - On-device by default - no sign-up, no account - Use Notion? Connect it (Islet Pro): two-way sync with your task database - Multiple databases for chores, work, study (Islet Pro) - Export to Markdown/JSON anytime Built to trust - Offline-safe - completions and memos never get lost; they sync when you're back online - We don't store your data on our servers. Everything stays on your device and in your Notion. Note: A Live Activity lasts up to 8 hours per session (an iOS limit); you'll be notified before it ends. Notion is a trademark of Notion Labs, Inc.
