The studio
Starfathom is the publishing brand of STEFANCHO LABS, a one-person studio in South Korea. We design, build, and ship apps for iOS and Android, and we release them under our own name rather than through a client or an agency.
The name takes the two ends of that scale and puts them in one word. Neither is a market we work in. They are the size of thing the studio likes to think about, and they are why the index below has a passport-photo tool next to a cold-water log next to a stock app. What those share is not a category. It is that each does one thing a person actually needs on a given day, and has to be worth opening again tomorrow.
Everything is made in-house. We write the code, produce the store assets, run the release pipeline, and answer the support mail ourselves. That is also why this site is short.

Internal tools
Starfathom Ads Manager is the in-house tool we use to advertise the apps above. It creates and updates Google Ads app install campaigns, adjusts budgets and bids against measured performance, and pulls cost-per-install reporting into a dashboard we read ourselves. It runs against our own advertiser account only. We do not sell it, license it, or manage advertising on behalf of anyone else.

Privacy
We do not collect personal information through this website. Each app has its own policy — see the Starfathom privacy policy for how our apps handle data and for links to the per-app policies.
