When you have to hand over your phone, open only the space you are fine showing. Bulbul is a decoy folder and a vault in one: every code opens a different space, and every code opens a real one, so nothing looks hidden. Text codes, patterns, and numeric codes each open a separate space for photos, files, notes, links, and web research. Decoy by design - Keep a decoy code and a real code side by side. - No list of spaces is shown anywhere in the app, not even how many exist. - Nothing looks locked, so nobody asks you to unlock it. Code-addressed spaces - Text codes, patterns, and numeric codes can each open a different space. - There is no exposed list of every space in the app. - There is no master password that opens everything at once. - Decoy spaces are natural: every code opens a real, separate space. Capture into the right place - Share files, photos, and links into Bulbul from other apps. - Pick the code for the space where the item belongs. - Save YouTube and web links as shortcuts inside the right project. - Pin widgets to jump directly into a specific space and tab. Work inside each space - File manager for folders, documents, images, PDFs, and videos. - Markdown editor for private notes and read mode. - Camera that saves directly into the active space, not your camera roll. - Built-in browser with a separate session per space. - Per-space iCloud sync controls when you want a space to stay local. Made for people who - Keep work files, family photos, project notes, and receipts in separate contexts. - Share a device but do not want one visible folder of private material. - Prefer opening only the space they need, instead of unlocking everything. Important - Forgotten codes cannot be recovered. - Bulbul stores data on your device and in the iCloud account you explicitly enable. Requires iOS 26 or later. Universal app for iPhone and iPad.
