Everything we have shipped, and what happened to it.

Small single-purpose tools built for a Korean super-app platform, shipped as a portfolio rather than as one bet.

Built one at a time on a platform that already had the audience, which is the opposite of how the product above was launched. Both figures are summed across the apps and neither is a count of people: a first open is somebody counted once per app they ever open, an active day is that same person counted again on every day they come back. The 6,295 days between the two are the whole of the return behaviour, 1.3 active days per first open, which is a weighted mean rather than the typical app: the median app is 1.09. Across complete months first opens fell from 6,141 in May to 2,093 in Aug, and return days from 1,664 to 835: both halves fell, acquisition faster. At least 69.7% of first opens were never followed by a return day. It is concentrated too: 3 of the 50 produced about 73% of the opens and the median app produced 93. They run inside that platform's app, so there is no public link to give, and the individual apps stay unlisted.
