Lens: PlusDaily’s sister app
Lens builds on PlusDaily and extends Direct Behavior Rating with Android, team workflows, phases, export, and deeper analyses.

PlusDaily stays intentionally lean: define a target behavior, rate quickly, and make development visible. That simplicity is the starting point. At the same time, school practice, counselling, and research quickly show where a broader frame becomes useful: multiple professionals, phases such as baseline and intervention, Android devices, export, and deeper analyses.
That is where Lens comes in: PlusDaily’s sister app for digital behavioral progress monitoring in schools.
What Lens adds
Lens keeps the core idea of PlusDaily: short structured behavior ratings should not disappear into scattered notes, but become an understandable trajectory. The focus remains the same: behavior is observed repeatedly, described clearly, and made readable over time.
The frame becomes broader. Lens is designed for iOS and Android from the start and is more strongly oriented toward school teams. Cases can be shared deliberately, ratings by different professionals remain traceable, and data can be exported in a structured way.
More features for more complex trajectories
Lens extends PlusDaily especially where support processes need more structure:
- target behaviors with clear scales and templates
- fast ratings during the school day
- offline capture with later sync
- baseline, intervention, and follow-up phases
- trajectory, trend, NAP, and Tau-U
- team sharing and CSV export
- pseudonymous cases and a privacy-oriented architecture
Lens should not promise more certainty than the data allow. If there are too few data points, or if a trajectory is unclear, the app should say so plainly. That matters more than a loud dashboard.
How PlusDaily and Lens fit together
PlusDaily is the fast, low-threshold app for Direct Behavior Rating on iPhone and iPad. Lens is the next, broader product line: cross-platform, team-oriented, and deeper in its analyses.
Put simply: PlusDaily makes it easy to get started. Lens extends the same idea for schools that want to use behavioral progress monitoring more systematically as a team.
