ReliCheck Quanta

Native to the Mac. True to your research.

The statistics software Mac researchers actually reach for: validated for social, behavioral, and health science, and built the way you work.

Apple Silicon · macOS 14 or later · notarized by Apple · v0.9.92 · subscription required after a 30-day trial

Import

Start from the file you already have.

CSV, TSV, Excel, Apple Numbers, SPSS .sav and Stata .dta all open directly, along with ReliCheck survey packages. No conversion step, no export from something else first.

Import

Variable types, sorted on arrival.

Quanta reads your columns and assigns types as the file opens. Continuous, ordinal, nominal. You confirm rather than configure, and the analysis menu adjusts to what your data can support.

Reliability

Every item, on one screen.

Scale and reliability analysis with the full item statistics table: item-total correlations, alpha if item deleted, and the scale summary. Setup on the right, results in the centre.

Reliability

Know which item is dragging the scale.

Alpha if item deleted sits beside every item, so a weak indicator is visible at a glance instead of being hunted for. Drop it, rerun, and watch the scale settle.

Correlation

Correlations that arrive publication-ready.

Pearson and Spearman with significance markers, sample sizes, and an APA 7 matrix that is already formatted. The table you see is the table you paste.

ReliCheck Intelligence

A plain-language read under every result.

ReliCheck Intelligence writes a sentence explaining what the number means, underneath the number. It runs on your Mac, so nothing is sent anywhere to produce it.

Modelling

Confirmatory factor analysis, with the fit indices.

CFA and structural equation modelling with the fit statistics reviewers ask for, reported together rather than one at a time.

Validated

The validation record is published, method by method.

Every method lists the reference it was checked against and how far the agreement holds. Univariate summary and linear regression are validated against NIST reference datasets, to nine digits and beyond. Read the validation record.

Report

Findings become a report as you go.

Results collect into an editable, APA-formatted report rather than waiting for a final assembly step. Tables arrive formatted. You write around them instead of rebuilding them.

APA 7

Tables that already follow APA 7.

Leading zeros, italics on the right symbols, notes in the right order, df where APA puts it. Export to PDF, Word or RTF with the formatting intact.

Private

Your data never leaves the machine.

Analysis runs entirely on your Mac and works offline. The network is used once to confirm your subscription and never for your data. For IRB-covered work, that is a one-sentence answer.

Native

One signed app. Built for Apple silicon.

Pure Swift on Apple's own maths frameworks. No R, no Python, no package manager. Written for the architecture rather than translated onto it.

Honest

It tells you what a result cannot support.

Reliability is evidence, not proof of validity. A group difference is association, not causation. Quanta labels small samples cautiously and says so on the result, where it matters.

Careful by default.

The software will not overstate a finding to look impressive. If the evidence is thin, the output says the evidence is thin. That is the whole design position. The safeguards are contextual recommendations, never restrictions: Quanta surfaces the analyses that fit your design and flags mismatches, and every test stays available to run.

It asks who your data represents. Before you analyze it.

A mean is only as honest as the sample behind it. Quanta's representation checks make that visible where statistical software never has: missingness by group shows whether nonresponse fell evenly or quietly removed one community from your results. Sample vs population tests your sample's composition against the benchmarks you enter and names which groups are over- or under-represented. Grouped descriptives flag small groups instead of collapsing them, so no one disappears from the table. Every finding starts from an answer to the question most analyses skip: who is actually in this data, and who is missing from it. In the base app, for everyone.

Quanta Advanced, for the heavier models.

An Advanced tier adds eight analysis families: multilevel models including ordinal, generalized linear mixed models, latent class and profile analysis, finite mixture models, survival analysis, mediation, moderation, and measurement invariance. Validated the same way as everything else. See the Advanced analyses or the pricing page.

Workflow

Setup on the right. Results in the centre.

The layout stays put as you move between analyses, so the thing you are reading is always in the same place and the thing you are changing is always in the same place.

Common questions

Does Quanta run on my Mac?

Quanta is built for Apple Silicon and requires macOS 14 or later. It is a single signed, notarized app: download it, open it, and work.

Can I trust the numbers?

Every statistic carries a published validation record checked against NIST reference datasets and published statistical standards. The record ships inside the app.

What files can I import?

CSV, TSV, Excel, Apple Numbers, SPSS (.sav), and Stata (.dta), plus ReliCheck survey packages. Variable types are detected on import.

Does my data leave my Mac?

No. Analysis runs entirely on your machine and works offline. The network is used only to confirm your subscription.

How do I buy it?

Start with a 30-day free trial, no account needed. Then subscribe in the app, or get it on the Mac App Store. One simple price for everyone.
