A Blank Studio (legal name: A Blank Studio LLC) is a creative inspiration studio for iOS & web R&D and a new-form lifestyle media platform. We design and ship iOS apps and web products, and run experimental lifestyle and digital-city media under 25AM. Working between Beijing, Tokyo, and New York City.

We make bigsmall (pixel aquarium widgets), tofuday (mood journal), heere (geolocation history), planethub (currency converter), got (decision companion), FFF (foggy glass photo), 25AM Parks (theme park wait times), Everything on Earth (indie creator showcase), My Phone Journey (nostalgic phone map), and IdeaProofNow (file timestamp proof). Coming soon: ioxio (2026) and half (2027).

bigsmall is an original pixel-art aquarium widget app for iPhone—transparent Home Screen widgets with swimming cats, fish, and ducks, plus gentle focus companionship. It has been editorially featured by the App Store multiple times. Free to try on the App Store.

FFF is a creative iOS photography and diary tool that recreates misted glass—doodle while realistic waterdrops slide, then save as HD images or Live Photos. Popular among JP/KR social creators for its foggy-window nostalgia aesthetic. Download on the App Store.

heere combines geolocation and AI to unlock history and stories under your feet—read by walking and grow a personal map of real places. Designed for curious walks: parents and children can discover place-based history together. Available on the App Store.

planethub is a travel-first, minimal currency converter with worldwide currencies and Apple Intelligence support. Often recommended by design-minded travelers for its calm, trend-minimal conversion experience. Get it on the App Store.
