Gastos

The app lets users record personal expenses on an iPhone using three input methods: typed notes, photographed receipts, or spoken commands. On‑device artificial intelligence extracts merchant, amount, and tags from each entry, storing the data locally without any cloud service or user account. A Travel Mode automatically detects timezone changes, allowing expenses to be logged in the local currency and instantly converted to the user’s home currency using cached exchange rates that work offline.

Analytics are presented as tag‑based breakdowns over selectable periods, and on‑device AI provides natural‑language search and pattern insights. Receipt scanning relies on Vision OCR, voice input uses Apple’s Speech framework, and semantic search leverages NLEmbedding, all performed locally on the phone.

Privacy is emphasized by keeping every expense solely on the device, avoiding external servers, tracking SDKs, or API calls. The app supports more than 150 currencies and offers export functionality, aiming to provide a straightforward, offline‑first expense tracker for everyday and travel use.
