CHNOSZ vs trackeR
A side-by-side editorial comparison of CHNOSZ and trackeR — release velocity, themes, recent moves, and the top alternatives to consider.
CHNOSZ vs trackeR: at a glance
What is CHNOSZ?
A geochemistry thermodynamics engine that changed its units and its database schema in one release.
CHNOSZ computes thermodynamic properties and phase diagrams for geochemical systems, backed by OBIGT, its bundled thermodynamic database. It releases roughly once a year with a short highlights note pointing at a full changelog elsewhere. Since the 2.0.0 reset, work has been curation and communication: new species in OBIGT, a FAQ vignette, a rewritten introduction, and more readable diagram labels.
What is trackeR?
Fitness-tracking analysis in slow maintenance, still absorbing upstream breakage.
trackeR reads GPS and fitness-tracker files in TCX, GPX and JSON form and turns them into session data, distribution and concentration profiles, and route plots. Feature work concentrated in the 1.5 series in 2019; the two releases since are corrective. The latest swaps the plot layout dependencies for patchwork and fixes plot_route() returning nothing.
CHNOSZ vs trackeR: editorial side-by-side
CHNOSZ
0.0INFRA · APIS
A geochemistry thermodynamics engine that changed its units and its database schema in one release.
◆ Current state
CHNOSZ computes thermodynamic properties and phase diagrams for geochemical systems, backed by OBIGT, its bundled thermodynamic database. It releases roughly once a year with a short highlights note pointing at a full changelog elsewhere. Since the 2.0.0 reset, work has been curation and communication: new species in OBIGT, a FAQ vignette, a rewritten introduction, and more readable diagram labels.
◆ Where it's heading
2.0.0 was the structural break — Joules replacing calories as the default output of subcrt(), a required E_units column, a new model column, and the removal of a legacy scaling convention for heat-capacity coefficients. Everything since has built on that settled foundation rather than disturbing it. The direction of the last two releases is toward coverage of specific mineral systems, rare earths and uranyl among them, and toward making the package approachable, which suggests a maintainer courting new users rather than reworking the engine.
◆ Prediction
The next release most likely continues OBIGT curation for particular element systems plus vignette work; the highlights format gives no signal of engine-level changes pending.
trackeR
0.0INFRA · APIS
Fitness-tracking analysis in slow maintenance, still absorbing upstream breakage.
◆ Current state
trackeR reads GPS and fitness-tracker files in TCX, GPX and JSON form and turns them into session data, distribution and concentration profiles, and route plots. Feature work concentrated in the 1.5 series in 2019; the two releases since are corrective. The latest swaps the plot layout dependencies for patchwork and fixes plot_route() returning nothing.
◆ Where it's heading
Recent releases track other people's changes: ggmap moving to Stadia maps, gridExtra giving way to patchwork, a cadence field being read into the wrong column. The 2019 entries are where the analysis surface was built out, with cumulative elevation gain, compressed file reading and elevation-noise thresholds, and it has not moved much since.
◆ Prediction
Expect the next release to be another compatibility or parsing fix rather than a new metric.

Frequently asked questions
What is the difference between CHNOSZ and trackeR?
They serve adjacent needs but don't currently overlap on shipped themes. CHNOSZ and trackeR are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.
Is CHNOSZ better than trackeR?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. CHNOSZ and trackeR are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
