Carpe!

Carpe! is a mobile data capture app for teams that need structured records with built-in cryptographic integrity. Create local databases and tables, collect data in the field, connect BLE devices, and generate tamper-evident proofs for individual records as data is written. Carpe! is designed for workflows where trust in captured data matters: inspections, field operations, asset tracking, logistics, environmental monitoring, research, and sensor-based data collection. What you can do with Carpe!: • Create and manage local databases and tables directly on device • Capture structured records with custom fields and repeatable forms • Enter data manually or collect it from connected BLE devices • Scan QR codes and barcodes into records • Read supported NFC tags on compatible devices • Attach photos, audio, and other field inputs to records • Capture location coordinates when needed • Configure reusable insert workflows for faster data entry • Automate inserts from BLE characteristics with configurable decoding and field mapping • Store data locally on your hardware • Generate tamper-evident, record-level cryptographic proofs as data is inserted Carpe! combines operational data capture with verifiable integrity. Key capabilities: Flexible local data model Define the databases, tables, and columns you need for your workflow. Carpe! supports simple forms, repeat inserts, and structured capture without requiring a remote backend. BLE device ingestion Connect compatible Bluetooth Low Energy devices and map incoming values directly into database records. This makes Carpe! suitable for demos and production workflows involving sensor data such as temperature, environmental measurements, or other device telemetry. Field-ready capture Use built-in support for manual entry, barcode and QR scanning, NFC tag reads, media capture, and geolocation to collect records at the point of activity. Tamper-evident integrity Carpe! notarizes data at the record level. As records are created, the app computes cryptographic proof material that can be used to demonstrate integrity of captured data over time. Local-first operation Your captured records stay on your device unless you choose to export or synchronize them through your own workflow. Carpe! is designed to support data ownership and local control. Carpe! is useful for: • Field inspections and site visits • BLE sensor logging • Asset and inventory workflows • Chain-of-custody style recordkeeping • Research and measurement capture • Operational data collection with integrity requirements Important notes: • BLE features require compatible Bluetooth Low Energy devices • NFC features require a compatible iPhone • Some capture modes depend on device hardware and permissions Video demos: Carpe!
