This is Matinmat app to help customers figuring out how to assemble all the pieces present in their projects made of sheets of foam. The original model has been split into a collection of numbered blocks, a 3D view of the blocks is the standard view. Each block appears of a different color and numbers appear over each block. The user can later press on one of the blocks to get the detail of the pieces that need to be stacked to create that particular block. The app can visualize .STL and .OBJ formats too.

FlowFlow turns your voice into an organized, searchable memory that lives on your own devices. Record a thought. FlowFlow transcribes it, gives it a title and tags, and files it. Later, ask questions in plain language and get answers drawn from your notes, with sources you can open. RECORD AND TRANSCRIBE - One-tap voice capture with a live waveform, pause, and resume. - Transcribe in the cloud with Soniox or entirely on-device with local Whisper models. - Local transcription works in airplane mode, and the audio never leaves your iPhone. - Start a recording from Control Center or the Lock Screen. - Import PDF, DOCX, TXT, Markdown, and CSV files. OCR supports scanned PDFs. ASK YOUR NOTES - Ask questions and get answers with sources you can open. - Search combines keywords, semantic retrieval, and reranking. - Enable web search for a conversation when you need recent information. - Save an answer or an entire thread as a note. - Use an OpenAI API key or connect your ChatGPT subscription for chat. - An OpenAI API key is still required for embeddings and semantic search. ORGANIZE - Automatic titles and tags as you write. - Hierarchical folders and note threads that read from top to bottom. - Related notes surfaced automatically. - Notes grouped by date for easier navigation. - Turn a request such as βpick up the kids at 5 PMβ into an iOS reminder.

Your private notes remain outside it. - Manage members, themes, and permissions from the sidebar. WORK WITH HERMES - Give Hermes access to one specific space. - Choose read-only or read-write access. - Revoke or regenerate its access at any time. - Hermes can read authorized folders, notes, and threads, then contribute in the same space as your team.

API keys and pairing secrets are not included. ASSISTANTS AND CONNECTORS - Connect available services such as Google Sheets and limit an assistant to selected resources. - External actions that require approval are shown before execution. - Hermes can write in a space only when you grant it read-write access.
