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: β€’ Tap the microphone in the β€œAdd Task” bar β€’ Press and hold the large + button β€’ Assign the iPhone Action Button: Settings > Action Button > Shortcut > β€œ0F Voice Task” Speak your task and tap β€œDone.” 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.
