Best Notes App for Statisticians on iPhone

Statistics is a discipline where the decisions made before running an analysis matter as much as the analysis itself. Notes that capture why specific methods were chosen, what assumptions are being made, and what the results actually mean — not just their p-values — are the difference between good and great statistical work.

What Statisticians Capture in Nemos

Analysis design notes: - Research question operationalization: how the conceptual question maps to the statistical test - Method selection rationale: why this model over alternatives - Assumption check notes and how assumptions were verified - Power analysis rationale and sample size justification

Data notes: - Data quality observations: missing data patterns, outliers, unexpected distributions - Variable construction rationale - Data transformation decisions and their justification - Known data limitations and their implications for conclusions

Methodological development: - New methods encountered at conferences or in literature - Implementation challenges and how they were resolved - Simulation study observations and parameter sensitivity

Collaboration notes: - Client question translation: what they asked vs. what they need statistically - Feedback on analysis interpretation from non-statistician collaborators - Communication strategies that worked for specific audiences

The Analysis Decision Note

A decision note worth keeping:

``` [Analysis: Longitudinal depression scores, RCT data] Date: 2026-03-16 | Method: Mixed effects model (REML) Decision: Random slope + intercept vs. random intercept only Rationale: LRT p=0.02 favoring random slope; theoretical basis for heterogeneous trajectories Assumption check: Residuals approximately normal, no systematic variance pattern Caveat: Converged with optimizer warnings — check with different optimizer Outstanding: Sensitivity analysis with GEE for robustness check ```

Communicating Statistical Results

Statisticians who communicate well keep notes on what worked:

• Which visualizations clarified vs. confused a specific audience
• How to explain confidence intervals to clinicians vs. engineers
• Which analogies helped vs. created new misconceptions

These notes become a communication toolkit that makes every collaboration more effective.

FAQ

Is Nemos appropriate for keeping analysis code or output? No — code belongs in your version control system, output in your analysis project. Nemos captures the reasoning around those artifacts.

What about preregistration notes? Yes — preregistration plan development, analysis decision log before data unblinding, and deviations from preregistration with rationale are all appropriate.

Is Nemos useful for biostatisticians? Yes — same principles apply to clinical trial analysis, survival analysis decisions, and regulatory submission methodology notes.

What about Bayesian analysis decisions? Prior specification rationale, posterior predictive check observations, and sensitivity to prior notes are excellent Nemos content.

Can I capture notes from statistics conference talks? Yes — new methodology notes, implementation insights, and connections to your own work are appropriate.

What about consulting statistician work? Client engagement notes, analysis scoping decisions, and interpretation communication notes are all appropriate.
