Struggle is a private AI companion application designed for iPhone users on heavy days. The app provides a conversational space where users can express themselves without needing to find the right words or have their thoughts fully untangled. It functions as a place to vent, clear one’s head, and work through overwhelming feelings one small step at a time. The app is explicitly not a therapy service, and its stated purpose is to offer a low-pressure starting point for processing difficult emotions such as anxiety, loneliness, or a low day. Users interact with Struggle directly in chat, speaking in their own words and in their preferred language among 50 supported languages. The app responds with calm replies, honest questions, or suggested next steps. Conversations can be revisited later, and users may choose to save specific steps they want to recall. The user controls certain personalization elements, including what the app calls them, which support focuses matter most, and the app’s color scheme. A saved step can optionally be enabled to influence future replies, and this decision is left to the user. Privacy is a core design element. Chat history remains on the user’s iPhone rather than on the app’s servers. To generate replies, recent messages, the chosen name, and selected support focuses are transmitted through the app’s server to the AI provider, but conversation transcripts are not stored in the app’s database. Only user-confirmed saved steps are synchronized with the server, and only those enabled steps may be included in later messages to the model. The app contains no ads and no cross-app tracking. Struggle is available on the App Store and is free to start.
