How Tiimo grows
17 tactics and 11 figures from 2 interviews.
tiimoapp.comTiimo is a daily planner aimed at busy multitaskers and neurodivergent users, and was Apple's App of the Year 2025. It grew through paid ads kept under a cost-per-customer ceiling, steady pitching to Apple's editors, and product work focused on getting new users to finish tasks on their first day. Two moves that pulled away from the core planner, a pricier tier and a weak Android app, were rolled back.
- Tiimo put most ad spend on broad Meta campaigns and about 30% on Apple Search Ads for ADHD keywords, which it reported as up to 50% cheaper per trial, with ADHD-identifying users converting 3x better.Tiimo (1)Tiimo (2)
- Tiimo ranks product work by tasks completed on day zero, which it found predicts day-one return; a celebration animation when a task is marked done brought 17% more completed tasks.Tiimo (1)Tiimo (2)Tiimo (3)
- Tiimo kept one or two App Store in-app events live each month, nominated itself whenever it adopted a new Apple technology, and built WWDC features by September, describing this as part of its path to App of the Year 2025.Tiimo (1)Tiimo (2)
- Tiimo caps blended cost per customer at about $10.50 and checks it weekly, and it cut influencer spending after judging that it built brand more than revenue.Tiimo (1)Tiimo (2)
- A 2024 tier with expert courses and body doubling at about 3x the price hurt growth and was parked, while a lagging Android app was shut down and rebuilt from scratch, relaunching in May 2026.Tiimo (1)Tiimo (2)
