MetaTimer – Building a timeboxing app for ADHD brains

The problem with time management apps

Most productivity apps are built for neurotypical brains. They assume you can estimate how long things take, switch tasks on command, and stick to a rigid schedule. If you have ADHD — or just a brain that resists structure — these tools create more anxiety than focus.

I wanted to build something different. MetaTimer is a timeboxing app designed around how ADHD brains actually work — not how productivity gurus think they should.


Why timeboxing, not Pomodoro

Pomodoro forces you into fixed 25-minute blocks with mandatory breaks. It doesn't care if you're in flow or if your task needs 7 minutes or 2 hours. Timeboxing is more flexible — you decide how long each task gets, and the timer keeps you honest.

  • No rigid intervals — Set the time that makes sense for each task
  • Playlist-style flow — Tasks queue up like songs, so transitions feel natural
  • Visible progress — See exactly where your time goes in real-time
  • Pause without guilt — Life interrupts, and that's okay

The key insight: ADHD brains need gentle structure, not strict enforcement. MetaTimer provides rails without making you feel trapped.


Designing for focus, not anxiety

Every design decision in MetaTimer was filtered through one question: does this reduce cognitive load?

One task at a time

Instead of showing a massive to-do list, MetaTimer shows only your current task and a clear countdown. This eliminates the overwhelm of seeing everything at once — a major ADHD trigger.

Estimated vs. actual time

One of the hardest parts of ADHD is time blindness. You genuinely don't know how long things take. MetaTimer tracks estimated vs. actual time, building your awareness gradually without judgment.

  • Task initiation support — The hardest part is starting. A visible timer creates gentle urgency
  • Reduced decision fatigue — Plan once, then just follow the flow
  • Progress visibility — Daily stats show you what you actually accomplished
  • Distraction-free UI — Minimal design keeps you in the zone

The tech behind it

MetaTimer is a native iOS app built with Swift. I chose native over cross-platform for one reason: performance and feel matter for a focus tool. Every animation, every haptic, every transition needs to feel instant and intentional.

  • Swift & SwiftUI — Native iOS for the smoothest possible experience
  • Local-first — No account required, no data collection, no cloud dependency
  • iOS 16.6+ — Supporting a wide range of devices
  • 35 MB — Lightweight, no bloat

Privacy was non-negotiable. MetaTimer collects zero data. Your tasks, your time, your business. Everything stays on your device.


What I learned shipping a solo product

Building MetaTimer as a solo designer-developer taught me things no team project ever could:

  • Scope is everything — I cut features ruthlessly to ship something focused and useful
  • Design for the edge cases — ADHD users will use your app in ways you didn't expect. Flexibility beats perfection
  • Feedback loops matter — TestFlight beta testers shaped the product more than any assumption I had
  • Shipping beats polishing — Version 1.0 wasn't perfect, but it was real

Who it's for

MetaTimer isn't for everyone — and that's by design. It's built for:

  • People with ADHD seeking gentle structure without overwhelm
  • Students preparing for exams who need focused study sessions
  • Remote workers juggling multiple responsibilities
  • Freelancers who need to track time for billing
  • Anyone who's tried Pomodoro and found it too rigid

What's next

MetaTimer is in active development. I'm building features based on real user feedback, not assumptions. The roadmap is driven by one principle: help people understand and reclaim their time.

If you want to try it, MetaTimer is free on the App Store. No ads, no subscriptions, no data harvesting. Just a tool that respects your time and your brain.
