One small app per problem: no platform, no dark patterns, in and out again.
Curated theme guides
7,600+ hand-written entries across 11 categories and 100+ themes. Free, ad-free, in Simplified Chinese.
Idle realm builder
An idle conquest campaign you never pay to win: four ages, nine realms, no IAP, no account.
Offline duck shooting gallery
Four marshes, 36 levels, one gunning station. Two thirds of the flock clears a level; stars live above that. No IAP.
Local voice notes & organizer
Hold, speak, and it is filed as a to-do or a memo — transcribed on device. No network, no ads, no account.
Carousel maker
Paste your words and they split into pages. 20 templates, your own photos, three ratios, HD PNG export. No sign-in.
We build small, single-purpose apps: one job done properly, no dark patterns, and as much of your data as possible kept on your device.
