Zero-Friction Tasks is the personal task manager for busy individuals who simply want to get things done – without signing up, without a mandatory subscription, and without complexity. New: just speak your task. NEW: VOICE TASKS. SAY IT – IT BECOMES A TASK. Hands full, in the car, on the go, or cooking? Speak a short note and it lands directly in your list. There are three ways to start: • Tap the microphone in the “Add Task” bar • Press and hold the large + button • Assign the iPhone Action Button: Settings > Action Button > Shortcut > “0F Voice Task” Speak your task and tap “Done.” Recording starts immediately and stops automatically after no more than 20 seconds. Only the recognized text is saved – never the audio recording. When iOS supports on-device speech recognition, it runs directly on your iPhone, so your voice never leaves the device. NO ACCOUNT. NO EMAIL. NO PASSWORD. Download and get started in 10 seconds. No registration. No confirmation email. No password to forget. Zero-Friction Tasks respects your time from the very first second. WHY ZERO-FRICTION TASKS? Most task apps demand an account before you can even begin. Many hide essential features behind complicated plans or store your data unencrypted. Zero-Friction Tasks takes a different approach: • No account required – start in seconds with a simple sync code • Free to start – no trial and no credit card required • End-to-end encrypted (AES-256) – the server never sees your tasks in plain text • Offline mode – core functionality remains available without a connection • Real-time sync – iPhone, Android, Windows, web, and macOS FOR INDIVIDUALS, NOT TEAMS. No Kanban boards. No Gantt charts. No collaboration features. Just your tasks – fast, private, and always available. KEY FEATURES: • Voice Tasks on iPhone – speak tasks instead of typing them • Global hotkey on Windows (Alt+Space) – capture tasks without switching apps • iOS widgets for the Home Screen, Lock Screen, and Today View • Lists for work, home, shopping, and anything else • Pinned tasks – keep what matters at the top • One-time and recurring reminders • Dark Mode and offline mode • Drag-and-drop sorting Start for free. No sign-up. Your tasks, your way. Terms of Use (EULA): https://zerofriction.app/terms Privacy Policy: https://zerofriction.app/privacy

Read full description

Synca is a lightweight app built for capturing ideas, collecting to-dos, and keeping them in sync across your devices. Sometimes you think of something important on your phone, only to find that it does not show up where you need it later. On some managed work devices, iCloud sync may be unavailable, which makes built-in note and reminder apps less practical for cross-device use. Synca is designed for exactly that kind of workflow. You can quickly save text or images on iPhone and have them synced to your Mac, so your work notes, personal reminders, and everyday ideas stay available when you need them. Key features: · Fast text capture · Image sending and viewing · Real-time sync between iPhone and Mac · Clear completed items while keeping history · Simple sign-in with Sign in with Apple · Great for work ideas, quick to-dos, personal notes, and cross-context capture Why Synca: · Keeps your capture workflow available even when iCloud sync is not · Cleaner and more focused than sending messages to yourself · Lighter than a traditional notes app for quick capture · Helps you save ideas instantly before they disappear · Web access support: https://synca.haerth.cn/ Synca makes it easier to capture first, organize later. · Privacy Policy: https://synca.haerth.cn/en/privacy-policy · Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Plans and attachment storage: The free plan includes up to 20 new entries per day, image sync, 100 MB of attachment storage and 3-day attachment retention.
