The founders reported 127K downloads and over $18K in the last 30 days, mostly from a lifetime plan.

Cat on Chair had dozens of REDnote followers beta test for a month and got about 3,000 downloads in launch week, but bugs such as data not syncing lasted until a stable version around Dec-Jan.Cat on Chair (1)Cat on Chair (2)

Cat on Chair's 7 tactics

Cat on Chair · B2C · cat-themed focus timer app

Invite dozens of REDnote followers to beta test for a month before launch

~3,000 downloads in launch week, but serious bugs remained for months

Once the first version was ready in August 2025, invited dozens of people on REDnote (where the co-founder already had an illustration audience) to beta test. Spent about a month gathering feedback, fixing bugs and iterating, then launched on Aug 27.

Launch first on REDnote, where your co-founder already has followers

~3,000 first-week downloads; a few small viral moments; users still mostly Chinese/Taiwanese

The co-founder (girlfriend, the illustrator) already had a REDnote account showing her illustrations with some followers, so they started there: beta recruitment and early promotion happened on REDnote, making Chinese and Taiwanese users the core market. Now expanding to English/worldwide audiences.

Turn a plain Pomodoro timer into a cat game with collectible furniture and cats

Over $18K in the last 30 days; 127K downloads in a crowded category

Instead of competing on timer features, themed the app around cats: a hand-illustrated cat jumps on the chair while you focus. Borrowed Animal Crossing-style customization (different cats, furniture, animated backgrounds) bought with rewards from sessions, gave each cat quotes based on its backstory and personality, and used the co-founder's distinctive illustration style. Guiding question: how to replicate the physical experience of having a cat in a digital app. Ryan advises studying competitors' reviews and remixing mechanics from games.

Have the cat leave a gift after a finished session, and trash if you quit

Inspired by memes of cats bringing dead mice to owners: after a successful focus session the cat leaves a gift; a failed session leaves trash. Gifts are collected and can be sold for fish (in-app currency) to buy cats, furniture and backgrounds in the shop. Users can also extend focus by 10 more minutes instead of taking the break.

Let users pet the cat: it meows when tapped or when you say its name

Collected feedback via UserDroid (free feedback board). Users asked to interact with the cat, so a meow animation was added that triggers when you tap the cat or say its name out loud.
