Purpose-Built
An offline powder X-ray diffraction workbench for pattern import, baseline treatment, peak finding, d-spacing conversion, reference overlays, crystallite estimates, and evidence-rich exports.
One-time iPhone and iPad app
Braggsight
Powder diffraction analysis
Core Features
- Import two-theta and intensity text or CSV patterns
- Apply visible background, smoothing, normalization, and K-alpha settings
- Find peaks and convert two-theta to d-spacing with Bragg's law
- Overlay user-provided reference sticks and compare peak residuals
- Estimate Scherrer size with every wavelength and broadening assumption shown
Private by Design
No account, subscription, ads, tracking, third-party analytics, or developer-operated backend. Core features work offline, and your work stays on device unless you deliberately share or export it.
Use It Responsibly
Braggsight is an exploratory and educational tool, not a phase-certification system. Instrument broadening, sample displacement, texture, overlap, and reference quality can dominate conclusions.
