Our Mobile App Made $85K in 8 months

Brothers Jack and Nick Sweeney built Coherence, a breathwork app, after validating ideas with content first. They test ideas as posts on X, move winners to Instagram/TikTok short-form, then YouTube. A viral 'vortex breath' tweet led to the app; the MVP was built with Cursor and launched February 2025. A polarizing short video ('something they don't want you to know') hit ~8M views and became a series. Eight months in: 15,000 downloads, ~$85K revenue, ~$11K/month average, $22K best month, costs $5-6K/month at ~50% margin.

A viral 'vortex breath' tweet became the app; ~$85K in 8 months

Before building anything, both founders posted content on topics that genuinely excited them (Jack: threads on spiritual/esoteric topics; Nick: breathwork). They watched which ideas went viral. Jack's tweet about the 'vortex breath' went super viral overnight, which became the idea for the app; they then built the MVP with Cursor in a few weeks and launched February 2025. 'We basically reverse engineered the content into the app.'

Founders say it shows what the market wants; no numbers

Use X as an 'idea battleground': post many ideas as text. When a post gets traction, treat it as validated and turn it into an Instagram short-form script, posting on Instagram and TikTok. If the short video does well, make it into a YouTube video. Move 'upstream' to longer, more impactful formats only with proven ideas.

Founder says it lets them out-post everyone; no numbers

Nick's playbook: pick a painful niche and make lots of content about it; batch content ideas weekly; film in bulk, 30-60 videos in a session ('hook, film, done, another one'), giving about two months of content; see which pieces work; then 'outmarket everyone': make as many Reels as possible, hire clippers if you can. As bootstrapped founders, Nick is the face and posts 'like a madman every single day'. Planned next step: put Spark and Meta ad money behind the winning organic videos to test willingness to pay.

~8M views across platforms, 1M the next day; turned into a series

A short health video framed in a polarizing way, opening with 'Do you want to know something that they don't want you to know?' ('they' left ambiguous, implying forces keeping you sick). Nick almost reshot it three times because he thought it was bad. After it took off it was turned into a recurring series.
