Most timer apps are clocks with a countdown. Ferro is a living ferrofluid creature that thinks, reacts, speaks, and runs every timer you will ever need. UNLIKE ANYTHING IN THE APP STORE Ferro is the most beautiful timer ever made for iPhone. Not a skin. Not a theme. A new object, built from the ground up with real fluid physics and a visual language no other app has. THE BLOB Ferro is not a UI element. It is alive. It breathes on your home screen. Churns when it is thinking. Pulses with the intensity of your session. Freezes perfectly still when you pause. Touch it, it parts and reforms. When you finish, it celebrates. Every state means something. That is not decoration. That is design. ALL YOUR TIMERS. ONE APP. Describe what you need and Ferro builds it instantly. Or create it by hand, exactly how you want it. Focus and Deep Work. HIIT Intervals and Tabata. EMOM and AMRAP. Pomodoro and Flowmodoro. Breathing and Meditation. Countdown and Stopwatch. Custom plans for cooking, ladders, anything you can name. Combine them into unique sequences! Twelve timer types in one place. You will not need another timer app. THE AGENTIC AI Tell Ferro what you need. It does not just listen, it thinks. In seconds it reads your intent, picks the right timer type, structures every phase, names the session, and is ready. "4 rounds of Tabata, 3 sets." "Flowmodoro, keep me in it." "Something to wind down." Builds that would take minutes by hand, done before you finish the sentence. Then it stays with you. It speaks at the right moments, with the right tone, knowing exactly where you are in the session. "Smells close." when your pasta is nearly done. "Last one. Everything." on your final round. Context aware. Never scripted. Never repeated. This is not a timer with AI bolted on. Ferro's brain is the product. PICK WHO RUNS YOUR SESSION Personalities change how Ferro behaves, not just how it sounds. One keeps you steady. One doesn't care about your feelings. You decide how present it is, from nearly silent to always there. Strong language is opt in and off by default. And it sounds real. The voice breathes, times its pauses, and carries whichever personality you picked. FLOWS Chain timers into one sequence and run it hands free. Warmup, work, rest, repeat, cooldown, in a single tap. Build it yourself in the editor, or describe it and let the AI structure the whole thing. FOCUS SHIELD Block the apps that break your focus for the length of a session. They come back the moment the timer ends. YOUR PROGRESS Streaks, banked time, personal records, badges, and daily missions. Every session you finish is counted, and you can see exactly where your time went. ON EVERY SURFACE Live Activity with controls on the Lock Screen and the Dynamic Island. Home Screen widgets. Control Center controls. Siri. FERRO PRO Ferro Pro unlocks the AI, the voice, and Flows, with a 3-day free trial. Weekly and annual plans.
