Competitive teardown · 2026-08-18
Tiimo, dissected.
Copenhagen, founded 2015, three million downloads, iPhone App of the Year 2025. The best-designed thing in our neighbourhood — and the most useful competitor we could have asked for, because its wound is in a place we cannot bleed from.

Founders Helene Norlem and Melissa Wurtz; Melissa has ADHD and dyslexia, which they state plainly as the origin of the product. Features shipped: a visual timeline, an AI co-planner, a focus timer, brain-dump to-dos, calendar and reminders sync, widgets, up to five family profiles, and a courses-plus-community hub. It runs on iPhone, iPad, Mac, Android, Watch and web. This is a mature, well-funded-looking product with a decade of head start.
Why they won
Five things they got right before anyone else.
1
Lived experience used as a design method, not a marketing line.
A founder with ADHD, and every feature stated to be shaped with neurodivergent users, clinicians and researchers. It shows in the product, which is why the awards followed.
2
They made time visible.
The core insight of the whole product: people with ADHD don't experience time as numbers. Tiimo draws it. Everything else is downstream of that one decision.
3
Inclusivity as craft rather than compliance.
Soft rounded forms, high contrast, custom icons per task, illustration instead of stock photography. It reduces cognitive load by design rather than adding an accessibility settings page.
4
Copy that validates instead of scolding.
"Stay focused, not frozen." "Structure you can see." They name the actual experience — freezing, not laziness — and never imply the user is the problem. This is the part we're competing with hardest.
5
Creator-led distribution, then Apple editorial.
Reviewers arrive naming the ADHD podcast or YouTube channel that sent them. The ADHD creator economy is the acquisition channel; Apple's editorial team is the multiplier on top. Nobody bought their way in.
The wound
The recent reviews are not the lifetime rating.
Lifetime average is 4.6 stars. But in the 49 most recent US App Store reviews, 16 of them — a third — are one or two stars. Sorted into themes, the complaints are strikingly consistent, and almost none of them are about the design.
≈6
Billing and cancellation
Charged during or immediately after the trial, refunds refused, no obvious way to cancel, and the app failing to recognise an active subscription. The single most damaging cluster — these are the angriest reviews, and they are about trust rather than product.
≈5
Reliability
Calendar syncs that silently don't appear, routines vanishing overnight, uncertainty about whether alerts actually fire. As one reviewer puts it, unreliability is disqualifying in a tool for people who cannot hold the backup in their head.
≈4
Onboarding and complexity
No instructions, a steep learning curve, and the sense of being handed a powerful thing with no way in. One one-star review lands it exactly: something "supposed to help with neurodivergence should not have this steep a learning curve."
≈4
The scheduling model itself
Tasks auto-starting and auto-completing whether or not they happened; no carry-forward for undone items; no deadline-until-done reminders; awkward twice-weekly repeats. The engine assumes the day goes to plan.
≈4
Integration gaps
Outlook and some Google calendars unsupported, no Todoist import, no bi-directional sync with Apple Calendar and Reminders. Named destinations for churned users: Structured and Routinery.
≈3
Resentment of the AI pivot
A perception that effort went into the AI co-planner rather than the core, plus discomfort at handing daily-life detail to a model. Their most loyal segment is also their most privacy-alert one.
Honest limits on this evidence: 49 most-recent US reviews is a small, self-selected sample, and recent-sorted reviews always skew negative because satisfied users rarely write in. The theme counts are my own classification, not Apple's. Treat the pattern as directional, not as a measured churn rate.
The structural crack
Tiimo is a plan.
A plan is a thing you fall behind.
Every complaint in the fourth cluster is the same complaint wearing different clothes. A schedule has to be decided in advance and then executed. The moment a day goes sideways — and for this exact customer, days go sideways — the plan becomes a document that is wrong about you. Tasks mark themselves done that you never did. Undone things don't carry forward. Open it on Thursday after skipping Tuesday and it shows you a version of your life that didn't happen.
Their tagline is "the planner people don't quit." It is an extraordinary line, and the recent reviews are quietly arguing with it — because a planner is structurally quittable. The plan degrades the second you stop feeding it.
A record does the opposite. Nothing we build can ever be wrong about you when you don't open it, because it only ever says what already happened. Close it for three weeks and it is exactly as true as the day you left. That is not a feature we thought of — it's a property of choosing memory over scheduling, and it is the one place a decade-old, award-winning incumbent cannot follow without rebuilding its engine.
The verdict
What we take. What we refuse.
Take
- Time made visible. Their founding insight, and it's correct. Our year grid is the same idea in a different tense.
- Validating copy. Name the real experience, never imply fault. They set the bar; we have to clear it.
- Accessibility as craft. Contrast, reduced motion, big targets, low cognitive load — built in, never a settings page.
- Creator-led distribution. ADHD podcasts and YouTube channels move real installs. That's the channel, not paid social.
- Small celebrations. Reviewers name the per-task celebration unprompted. Our fill and pop must be at least as good.
Refuse
- Scheduling. The moment we ask someone to decide their day in advance, we inherit their entire failure mode.
- Trial-to-charge friction. Their angriest reviews are billing, not product. Price visible, cancelling obvious, refunds honoured — already our rule.
- A learning curve. One habit, one dot, no onboarding flow. Anything a person has to be taught is a feature we haven't finished.
- AI as the headline. This exact customer is privacy-alert. If we ever use a model, it works invisibly on their own words and never asks for their life story.
- Feature surface. Every integration they lack is a promise they made. We promise almost nothing, so almost nothing can silently break.
Tiimo helps you plan the day.
We keep the proof you lived it.
