Choose a clear objective, protect 15–25 minutes for it, park the distractions that pull you away, and watch your progress add up. More structure than a timer — without becoming another task manager.

Vitamin-R turns “I should really get started on that” into a concrete block of focused time you can actually begin.
Getting started begins with knowing what “started” means. Name one immediate, specific, reachable objective — not a vague project or a distant deadline. A clear target is what makes the next 25 minutes possible.
Start a “time slice” of 15–25 minutes and give it your full attention. Vitamin-R keeps your objective in view and the clock counts down quietly, so you always know what you are doing and how long you have.
A stray thought — an email to send, an errand, an idea — costs you one line on the Now & Later Board instead of your concentration. Park it and get straight back to the task. Nothing is lost, and your focus stays where you put it.
Try it on the next task you’ve been avoiding.
A plain timer counts seconds. Vitamin-R runs the whole loop that actually gets difficult work done:
Vitamin-R is probably a good fit if you:
If you only want a minimalist countdown with nothing around it, Vitamin-R may be more than you need — and that’s completely fine.
The essentials sit up front. The depth is there when you want it.
Set one actionable goal and let customizable visual, audio, and spoken prompts keep you gently on task.
A trusted place for intruding thoughts, so interruptions cost a line of text instead of your concentration.
Every completed time slice is recorded, turning your effort into momentum you can actually see.
Tag time slices by project or client and export to CSV — a lightweight way to see where your hours go.
Hit a global shortcut from any app to bring up the command window, then set up and control a time slice without ever reaching for the mouse.

Alternate focused time slices with timed renewal breaks, optionally locking the screen. Prefer the classic Pomodoro Technique? Its timing and rhythm are built in.

Block distractions with white noise or set the mood with soundscapes, from busy coffee shops to quiet beaches.
Run it full, compact, or dockless. Tune notifications and workflow, or leave the defaults be.
Vitamin-R complements OmniFocus, Things, and other task managers, with direct integrations.
Immediate feedback keeps you motivated — and the log book quietly teaches you when you do your best work.

Vitamin-R is a complete time-boxing method rather than just a countdown. You set a single clear objective, work on it distraction-free during a time slice, capture intruding thoughts, and review analytics that turn your effort into visible progress. It also fully supports the classic Pomodoro Technique if you prefer it.
No. Vitamin-R complements task managers such as OmniFocus and Things rather than replacing them, with direct integrations for pulling in your tasks. It handles the doing; your to-do list handles the what.
Vitamin-R wasn’t designed specifically for ADHD, but many people with ADHD tell us its clear structure, stay-on-task prompts, and reminders make it particularly helpful for starting and holding focus.
