Pact helps you build a healthier relationship with your phone by adding intentional friction to distracting apps. HOW IT WORKS Select apps you want to limit. Start a focus session or set usage limits. When you try to open blocked apps, complete a quick puzzle first. The small pause helps you decide: do I really need this right now? FOCUS SESSIONS Block distracting apps for 15 minutes to 4 hours. Perfect for deep work, studying, or quality time with family. USAGE LIMITS Automatically shield apps after 15 minutes of daily use. Complete a puzzle to unlock 15 more minutes. Difficulty increases with each unlock and resets at midnight. EARN KEYS Earn 1 key for every 15 minutes of focus time. Use keys to skip puzzles when you really need access. Build a balance of keys as a reward for staying focused. WHY PACT? Unlike harsh blockers that frustrate you, Pact creates a mindful pause. The puzzle isn't punishment—it's a moment to reflect on your intention. Most people find that by the time they finish the puzzle, they no longer want to open the app. PRIVACY FIRST All data stays on your device. No accounts required. No tracking or analytics. We can't see what apps you block or how you use your phone. PACT PRO Unlock unlimited app blocking (free plan: 1 app), all session durations, and support indie development. Download Pact and reclaim your attention. Terms of Use: https://buildscalelabs.io/terms/pact Privacy Policy: https://buildscalelabs.io/privacy/pact

Caliu is a markdown notes app for people who write. No clutter. No toolbars in the way. Just a quiet canvas, your words, and a way to find them again later. Write in Markdown. Sync everywhere. Think clearly. It runs natively on iPhone, iPad, and Mac, and stays in sync with the web app. Everything works offline. Your notes live on your device first and travel only when there is a connection. • The writing page. Headings, lists, quotes, code blocks, and links format as you type. No preview pane, no switching modes. The interface steps aside so the writing can take over. • Tags, not folders. Ideas overlap, so one note can belong to many places. Nest your tags, colour them, search them. Organisation that matches the way you think. • Reminders that find you. Pin a time to any note and Caliu nudges you on whichever device you have picked up. Good for the things you would otherwise forget you wrote down. • Sync you never think about. Start on your Mac, finish on your phone. Your notes are already there. No sync button, no spinner, no waiting. • Just talk. Tap the mic and think out loud. Caliu transcribes, trims the filler words, and turns your voice into clean Markdown: real headings and lists, not a wall of text. • Long-term memory. Caliu keeps snapshots as you write. Scroll back through a note's history, preview any moment, and bring it back in a tap. • A mood, not a menu. Ten colour themes, light and dark, plus more than 30 fonts to make the page yours. Pick the one that matches the hour. • Export, share, own your work. Export any note as Markdown, plain text, HTML, ePub, PDF, RTF, or TextPack. Share a note as a public link when someone needs to read it. Nothing locks you in. • Notes that talk back. A full REST API and a built-in MCP server, so Claude, Cursor, or your own scripts can read and write notes on your terms. • Private by design. Your notes are nobody's business. No ads, no selling your data, no tracking you across the web, and nothing you write is used to train AI. Kept on your device first and synced encrypted, built in the EU under GDPR. Export everything or delete your account whenever you like. Deleted means deleted. Caliu Pro The heart of Caliu is free: writing, tags, sync, and offline everything. Caliu Pro adds voice dictation, version history, every theme and font, unlimited attachments, more export formats, and API access. Try it free before you decide. Made with care by a small, independent team of one. No setup. No clutter. Just your thoughts, kept warm.
