Key Insights

• Cat on Chair is a free Pomodoro timer that generated more than $18,000 in sales over 30 days. Its paid options include a $29.99 lifetime plan, a $19.99 annual plan, and family sharing for as many as six people.
• The app reached 127,000 downloads and nearly $80,000 in sales across eight or nine months. During the reported 30-day period, it received about 24,000 first-time downloads, while most purchases came from the lifetime plan.
• The product differentiates itself through cats, customization, and reward mechanics rather than a novel timer function. Users can personalize cats, furniture, and backgrounds, giving them reasons to return beyond the basic utility of managing focused work sessions.
• The initial app took several months to develop, beginning around May 2025 and launching on August 27. Dozens of Red Note users beta tested it for about a month, yet serious problems, including failed cross-device data syncing, remained after release.
• The app's largest growth surge came from organic social sharing. An Instagram app-collection post featuring Cat on Chair exceeded 2 million views, and a subsequent Threads post in Taiwan went viral, helping downloads and revenue double overnight.
• The app's concept began with a necklace depicting a small cat sitting on a chair. Ryan and his girlfriend connected that image with the calming experience of cats staying near their owners during work, then developed an app around that feeling.
• The engagement system translates cat behavior into digital rewards. A cat leaves a gift after a completed focus session and trash after a failed session, while tapping the cat or saying its name can trigger an animation.
• The app's character and visual identity came from the founders' personal interests and skills. Ryan contributed product design experience, while his girlfriend supplied distinctive illustrations and suggested Animal Crossing-inspired customization involving cats, furniture, and backgrounds.

Questions & Answers

Q: How did Cat on Chair make more than $18,000 a month?

Cat on Chair generated more than $18,000 in sales during the reported 30-day period by offering paid features inside a free Pomodoro timer. Its plans included a $29.99 lifetime purchase, a $19.99 annual option, and family sharing for up to six people. Most sales came from the lifetime plan, while viral social posts helped increase downloads and revenue.

Q: What makes Cat on Chair different from other Pomodoro timers?

Cat on Chair combines a standard focus timer with illustrated cats, customization, collectible rewards, and interactive behavior. A cat sits with the user during a focus session, then leaves a gift when the session succeeds or trash when it fails. Users can also personalize cats, furniture, and backgrounds, making the experience more playful and personal than a basic timer.

Q: How was Cat on Chair built with AI coding tools?

Ryan used an AI coding plan as his main tool for programming the iOS app after coming from a product design background rather than an app-development career. He also used RevenueCat for paywall and subscription management, an app store optimization tool costing $10 per month, and a free user-feedback board. RevenueCat cost roughly $200 to $300 depending on monthly revenue.

Q: How long did it take to build and launch Cat on Chair?

Development began around May 2025, and a simple Pomodoro timer was working after several weeks. Ryan and his girlfriend then expanded the concept with mechanics such as cat animations. The first version was ready by August, followed by about a month of beta testing and iteration with dozens of Red Note users. The app officially launched on August 27.

Q: How did Cat on Chair get its first users?

The founders began on Red Note because Ryan's girlfriend already had an account where she shared illustrations and had accumulated followers. They invited dozens of people from that platform to beta test the app, provide feedback, and identify bugs. After launch, Cat on Chair received about 3,000 downloads in its first week and experienced several smaller viral moments on Red Note.

Q: Why did Cat on Chair go viral?

Cat on Chair first benefited from smaller moments of attention on Red Note, but its major expansion followed an Instagram influencer's app-collection post. That post received more than 2 million views. Someone in Taiwan then shared the app on Threads, where it went viral again. This chain of exposure doubled the app's downloads and revenue overnight.

Q: How does Cat on Chair keep users engaged?

The app gives users more than a countdown timer by connecting focus sessions with cats, rewards, and customization. Successful sessions produce gifts, while failed sessions produce trash. Each cat has a backstory and personality, and users can change cats, furniture, and backgrounds. User requests also led to petting and voice-triggered animations that make the cats feel interactive.

Q: What lessons does Cat on Chair offer for choosing an app idea?

Ryan's experience suggests starting with an app category that already interests you, then studying competing products through app store reviews and social media. Cat on Chair did not attempt to reinvent the Pomodoro timer's core function. Instead, it combined that familiar utility with the founders' interest in cats, distinctive illustrations, customization ideas, and observations about how cats behave around their owners.

Summary & Key Takeaways

• Ryan, a former product designer, left a $200,000 job to build his own business. With help from AI coding tools and his girlfriend, he created Cat on Chair, a cat-themed Pomodoro timer. The app became his first released product and eventually generated more than $18,000 in sales during a 30-day period.

• Cat on Chair launched on August 27 after several months of development and beta testing. It received about 3,000 downloads during its first week, but serious bugs persisted until around December or January. Later, Instagram and Threads exposure accelerated growth, helping the app reach 127,000 downloads and nearly $80,000 in sales.

• The app stands out by recreating aspects of having a cat nearby while working. Cats accompany focus sessions, leave gifts after successful sessions, and leave trash after failed ones. Custom furniture, backgrounds, character stories, petting animations, voice interactions, and distinctive illustrations turn a standard productivity tool into a personalized experience.
