What is Fulcrum?

Fulcrum is betting its whole map stack on Esri, with a hard Google Maps cutoff on September 1.

Fulcrum is a field data collection platform, and nearly every entry in the last month touches mapping. The web app ships weekly fix batches for layer rendering (KML/KMZ, MBTiles, ArcGIS Feature Services), while iOS and Android push near-weekly builds against the ArcGIS SDK. The newest iOS build turns to app-level responsiveness - database queries moved off the main path and the record editor kept interactive while Photo FastFill works in the background.

What is TrialEmulation?

Target trial emulation held steady by dependency maintenance, not new methods.

TrialEmulation implements target trial emulation from observational data, using duckdb to handle the expanded per-period datasets that approach generates. Every release in the visible window is upkeep: two consecutive releases removing the archived parglm dependency, two fixing tests against testthat updates, and two tracking duckdb sampling changes. No methodological work appears in the feed since before February 2025.

Fulcrum vs TrialEmulation: editorial side-by-side

Fulcrum is betting its whole map stack on Esri, with a hard Google Maps cutoff on September 1.

◆ Current state

Fulcrum is a field data collection platform, and nearly every entry in the last month touches mapping. The web app ships weekly fix batches for layer rendering (KML/KMZ, MBTiles, ArcGIS Feature Services), while iOS and Android push near-weekly builds against the ArcGIS SDK. The newest iOS build turns to app-level responsiveness - database queries moved off the main path and the record editor kept interactive while Photo FastFill works in the background.

◆ Where it's heading

The direction is a full consolidation onto Esri. The legacy Google Maps engine retires on September 1 with automatic migration for anyone who has not switched, and Esri now carries Google's satellite and street basemaps so the imagery argument is neutralized. Underneath, the mobile SDK moved to ArcGIS 300.0.0 and ONNX on-device inference gave way to a new INFERENCE format. Two capabilities are visibly staged behind early access rather than shipped: Photo FastFill, and a GPS integration still described as Alpha.

◆ Prediction

Expect the weeks before September 1 to stay dominated by migration-shaped fixes and Esri parity work, with Photo FastFill the nearer of the two early-access programs to general availability given it is already running in shipped builds.

T0.0

Target trial emulation held steady by dependency maintenance, not new methods.

◆ Current state

TrialEmulation implements target trial emulation from observational data, using duckdb to handle the expanded per-period datasets that approach generates. Every release in the visible window is upkeep: two consecutive releases removing the archived parglm dependency, two fixing tests against testthat updates, and two tracking duckdb sampling changes. No methodological work appears in the feed since before February 2025.

◆ Where it's heading

The package is being kept installable rather than extended. Its dependency surface, duckdb for storage, parglm for fitting, testthat for checks, generates most of the release traffic, and CRAN archiving parglm forced two separate releases three months apart to fully excise it. The version numbering, still in the 0.0.4.x range after years, suggests the maintainers do not consider the API settled enough to promote.

◆ Prediction

Further releases will most likely be triggered by upstream dependency changes; the entries give no signal on when methodological work resumes.
