Scale and counting units
- > 66,000 unique UI screens — original Rico downloads described on the project page source
- > 9,300 Android apps — original Rico collection described on the project page source
- 10,811 human interaction traces — crowd-worker collection before automated exploration source
Project-page scope: screenshots paired with augmented view hierarchies, gesture coordinates, layout vectors and metadata. These observations are not action/task totals. The later semantic-annotation download is a related augmentation of screens, not an additional disjoint corpus. The retained original paper reports more than 72k screens from more than 9.7k apps while this project page says more than 66k screens and more than 9.3k apps; the difference is unresolved. Profile counts follow the project page and do not merge these populations. No train/validation/test partition or data license is established here; archives were not downloaded.

Scope and limitations
The official project page cites the 2017 Rico paper. The project page reports more than 66,000 screens, while the original publication reports more than 72,000. These source-specific counts are kept separate; the reason for the difference is not established by these sources. App counts also differ: the official project page reports more than 9.3k Android apps and the retained published abstract more than 9.7k. Profile counts use the project-page scope; no reconciliation is inferred.
