TL;DR

  • Figure: $606 a month (Monthly · 17 Oct 2026 · RevenueCat-verified (TrustMRR))
  • Proof level: Verified. The headline figure comes from RevenueCat through TrustMRR (an owner-authorised API connection to the payment provider, not a screenshot), synced on 17 Oct 2026. Figures are gross revenue, before AI, hosting and payment costs. What is not verified: that the business is run by one person (the founder says so in the profile), and any user counts, costs or growth stories written by the founder.
  • Size: One-person business, under $10k a month. "One person" is the founder's own statement, not verified.
  • For sale: The founder has listed this business for sale since 10 Oct 2026, so the owner may change.
  • Our verdict (6/10, opinion): A small, real example of what one simple app can make: about $600 a month in subscriptions, with no paid ads according to the founder. Photo-to-cartoon apps are a crowded category, and growth was slow for a year before picking up.

The story

A one-person iPhone app. The founder has not made their name public.

  1. Apr 2025 — ToonThis founded (TrustMRR listing)
  2. 10 Oct 2026 — Listed for sale on TrustMRR
  3. 17 Oct 2026 — $606 a month in subscriptions, RevenueCat-verified (TrustMRR)

Revenue dipped in early 2026 and has been climbing again since the spring, per TrustMRR.

Business model

  • What it sells: an iPhone app subscription that turns selfies into cartoon-style pictures.
  • To whom: social media users who want a fun avatar or profile picture.
  • Pricing: $6.99 a week or $24.99 a year (founder's profile).
  • How it gets customers: App Store search only, which is called App Store Optimization (ASO): choosing the right app name, keywords and screenshots so people find it when they search. The founder says no money is spent on ads.

Agent blueprint

Our suggestion — not how the founder did it
  1. Step 1

    Style agent

    Tests new cartoon styles and picks the ones users keep

  2. Step 2

    App Store agent

    Drafts App Store keywords, screenshots text and translations for approval

  3. Step 3

    Support agent

    Answers refund and subscription questions

Human in charge

A person approves money, public posts and key decisions. We don't estimate how much human work this saves.

How much runs on AI (our estimate): 3/5 · Difficulty: Medium

Our take (opinion)

  1. Pick one simple, fun transformation people want to share (a selfie into a cartoon).
  2. Build a small app that does only that, well.
  3. Work on App Store search: name, keywords, screenshots, and translations into other languages.
  4. Charge a small subscription and keep running costs low.
  • Skills: basic iPhone app building (or an AI coding assistant), App Store marketing
  • Audience needed: no, App Store search did the work here

Risks & limits

  • Many similar photo-effect apps compete for the same searches.
  • Gross revenue only: AI costs and Apple's commission are not shown.
  • October is only half over, so any October total is partial; the headline is the current monthly subscription rate.
  • Listed for sale since 10 Oct 2026, so the owner may change.
  • One-person team and no-ads growth are the founder's statements, not verified.
