If you have ADHD, the "best" task app isn't the one with the most features — it's the one you'll actually open when your brain is fighting you. TickTick and Things 3 are the two most recommended, and they solve the problem in almost opposite ways. Here's how they really compare when executive function is the bottleneck.
The short answer
Pick TickTick if you need reminders that nag you, a built-in Pomodoro timer, and habit tracking in the same place as your tasks. Pick Things 3 if visual clutter overwhelms you and a calm, beautiful interface is what keeps you coming back. TickTick fights forgetting; Things 3 fights overwhelm.
| What matters for ADHD | TickTick | Things 3 |
|---|---|---|
| Fast capture | Excellent (widget + natural language) | Excellent (quick entry bar) |
| Reminders that persist | Multiple, recurring, annoying-on-purpose | Single, gentle |
| Built-in habits | Yes | No |
| Focus timer | Yes (Pomodoro) | No |
| Visual calm | Busy | Best in class |
| Price | Free tier + ~$36/yr | One-time (~$50 all platforms) |
Why TickTick tends to win for forgetting
The ADHD failure mode is usually "out of sight, out of mind." TickTick attacks that with aggressive, repeatable reminders, a home-screen widget, and recurring tasks that reappear until done. The Pomodoro timer lives one tap away, so "I'll just start" becomes a real button instead of an intention. If your problem is that tasks vanish from your awareness, TickTick's noise is a feature.
Why Things 3 tends to win for overwhelm
Some ADHD brains don't forget the task — they freeze at a wall of red overdue items. Things 3's whole personality is calm: generous whitespace, satisfying animations, and a gentle "Today" list that doesn't scream at you. There's no habit tracker and no timer, which is either a dealbreaker or a relief depending on your wiring.
What neither app solves
Apps are great at storing intentions and terrible at supplying motivation. On a bad day you'll ignore any notification your own phone sends. What reliably moves ADHD brains is social accountability: knowing someone will see whether you did the thing. That's the gap Groop is built to fill — a small group and a daily check-in, so following through stops depending on willpower alone.
