Trustworthy field evidence. Offline on any phone.
An offline-first field collection app for research teams. Record
structured observations, raw photos, and GPS coordinates on any
phone beyond cellular reach.

Designed for bright sun, cold hands, and zero signal.
One calm question at a time. High-contrast typography that cuts
through glare, oversized touch targets for gloved fingers, and
immediate local commit on every step.
Four guarantees for data collected in the wild.
Fieldwork happens in harsh conditions. collect is engineered around
four technical guarantees that protect your data from capture to
archive:
-
Local-first durability: Observations and media
commit to IndexedDB before any network attempt, updating to synced
only upon server confirmation.
-
Unmodified media originals: Photos and audio
retain capture quality with SHA-256 checksums, with no
collection-path recompression.
-
Isolated attention checks: Periodic checks
evaluate contributor focus in memory, stripping questions and
answers before database commit.
-
FAIR export archives: Checkpoint exports package
canonical JSONL, CSV, RFC 7946 GeoJSON, DataCite 4.4 metadata, and
raw media into a single archive.
Sync that survives dead zones, captive portals, and battery drops.
Flaky cellular links shouldn’t jeopardize weeks of fieldwork.
Submissions commit to device storage first, media transfers resume
in chunks, and records mark synced only upon server-confirmed
receipt.
Lock survey versions. Monitor sync progress across the fleet.
Author locked survey contracts, onboard researchers with single-use
8-character codes, and monitor fleet sync readiness — tracking
received observations, pending device queues, and attention scores
in real time.
Detect surveyor fatigue without polluting research data.
During 8-hour field transects, fatigue causes rapid tapping without
reading. collect interleaves subtle instruction checks to measure
focus, stripping questions and answers in memory before database
commit. Device context and GPS coordinates record verifiable
provenance.
Deposit-ready research packages for open repositories and peer
review.
Export packages bundle canonical JSONL, CSV, RFC 7946 GeoJSON,
DataCite 4.4 metadata, and unmodified media with SHA-256 checksums
into a single verifiable archive.
Findable (DataCite 4.4)
Native datacite.json metadata kernel with DOI identifiers,
organizational creators, and license declarations for repository
deposit and institutional archiving.
Interoperable (RFC 7946 & JSONL)
Canonical JSONL stream, flat CSV tables, RFC 7946 GeoJSON spatial
features, and machine-readable data-dictionary.json with semantic
URIs.
Reusable (Byte-for-Byte)
Self-contained ZIP archives containing uncompressed original media
files, schema version histories, and SHA-256 integrity manifests.
