Simple Apps Making Big Money

Quick Intro

I found how some plain todo apps make $200K/month — and why it’s not as easy as it looks.

Main Points

  • Grit app reportedly earns $200K/month, Productive does ~$70K/month – from SensorTower/AppMagic data.
  • These apps focus on simplicity, high polish, and daily utility — not groundbreaking features.
  • Some users call out Grit’s bad UI, yet it’s still growing due to solving a real productivity need.
  • Marketing is critical: TikTok viral videos, influencer marketing (CalAI), and App Store optimization drive growth.
  • App Store launch can give a boost due to algorithmic visibility and higher intent users.
  • One user noted 200 conversions from just 2K downloads – showing how niche apps convert well.
  • Creators discuss gamification ideas (like Clash of Clans for habits) as a way to increase user retention.
  • Revenue ≠ profit. Many wonder how much these apps burn on ads, marketing, and infrastructure.
  • Some suspect inflated revenue estimates — SensorTower data is not always accurate (disputed by devs).
  • Several users cite TikTok as a cheap growth hack, especially for solo founders.
  • Others remind: “There are thousands of todo apps. Only a few succeed.” Execution > idea.
  • Comments also debate whether lifetime pricing ($50–$100) or subscription model ($4.99/month) is better.
  • Tools mentioned for low-cost scaling: Vercel (hosting), Supabase (DB) — useful for <100 users.
  • ADHD users complain most apps are either bloated or too simplistic — room for better UX.
  • Simpler SaaS = lower churn, higher long-term value — boring tools can be the most profitable.
  • Big followings (e.g., Twitter) help launches. One user said 100K followers = $10K in 2 weeks.
  • Even a basic tool like Calendly (no API) is worth $3B – showing UX + niche > feature sets.
  • Todo apps are described as “Kanban memes”, yet people still crave better brain-offload tools.
  • One user reminds: “Clean execution still wins.” Another: “Solve one clear problem really well.”

Extra Tips

  • Use viral short-form video (like TikTok) with repeat tries — one hit can drive growth.
  • B2C apps do better with founder-made TikToks than polished agency promos.
  • Even small-scale projects can seed future businesses — use low-cost stacks to test.
  • Gamifying simple tools increases perceived value, especially for habit-building apps.

Warnings

  • SensorTower/AppMagic numbers can be off — they are estimates, not financial reports.
  • Revenue without profit is common — big ad spend can eat up all earnings.
  • Building “yet another todo app” won’t work unless it truly stands out or markets well.

Mixed or Disputed Info

  • “Grit earns $200K/month” – mixed (AppMagic says yes, users question accuracy).
  • “CalAI reinvests all profits” – mixed (some agree, some say they had external backing).
  • “SensorTower is legit” – mixed (many devs report inaccurate app stats).
