FieldLog – offline-first data collection for community workers
A phone app for health surveyors, NGO enumerators and ag-extension workers in low-connectivity regions that captures structured field data, photos and GPS offline and syncs to a cloud dashboard the next time a vehicle passes a cell tower.
NGO field staff and community health workers running surveys in rural areas
- Forms engine that runs identically online and offline with on-device validation
- Conflict-aware sync that handles delayed uploads from many devices into one dataset
- GPS-tagged photo and audio capture that compresses for slow uplinks
- Supervisor dashboard with progress by enumerator and region as data trickles in
Hologram-style local-first frameworks aim to eliminate the three-library sync plumbing that every field-data NGO currently reinvents badly.
Sustained, documented demand: KoboToolbox, ODK, SurveyCTO, CommCare, SurveyGrid and Questbee all actively serve NGO/health enumerators, and dedicated 2026 comparison articles keep appearing — but the need is largely already met.Best Offline Survey Apps in 2026 - Clappia ↗KoboToolbox vs ODK vs SurveyCTO | M&E Studio ↗
Very crowded space with entrenched, often free incumbents: KoboToolbox offers a full Community Plan free to nonprofits (5,000 submissions/mo, 1GB), ODK is open-source, SurveyCTO and CommCare (Dimagi) dominate paid tiers — a Hologram-based newcomer has minimal differentiated whitespace.Pricing | KoboToolbox ↗Competitor Comparison - SurveyCTO ↗
Willingness to pay exists (SurveyCTO/CommCare have paying NGO customers), but KoboToolbox's free nonprofit tier and ODK's open-source model cap realistic pricing; a startup on an experimental Elixir stack will struggle to command the $21+/mo that incumbents charge.Pricing | KoboToolbox ↗KoBoToolbox Pricing & Plans (July 2026) - SaaSworthy ↗
The underlying need (offline-first data capture for low-connectivity field work) is durable and structurally growing with global health/agritech NGO spend; scores below 9 because reliance on Hologram (still pre-1.0) adds technology-stack risk to an otherwise evergreen market.Building Local-First Apps in Pure Elixir with Hologram ↗Hologram v0.10 just landed! - LinkedIn ↗
Risky build: Hologram is only at v0.10 (pre-1.0, called 'production-ready' in marketing but still alpha-grade in ecosystem), native GPS/photo capture and conflict-free sync on flaky cellular links remain non-trivial, and almost no production field-data apps exist on Hologram.GitHub - bartblast/hologram ↗
