Spotxel® Reader3.3.5 - App Store

Spotxel(R) Reader is a free, feature-complete app for image-based microplate-reader workflows and colorimetric assay analysis.

Use Spotxel(R) Reader to capture or load a microplate image, align the well grid, select the measured color channel, quantify well signals, define standards and unknowns, calculate a standard curve, derive unknown concentrations, review well data, and export assay results.

The guided, page-based workflow includes Camera, Image Analysis, Assay Setup, Standard Curve, Well Data, Assay Report, Purchases, and Settings.

Key features:
- Capture or load microplate images for analysis
- Quantify colorimetric well signals from plate images
- Select the measured color channel
- Align the well grid manually or with the Align Grid beta feature
- Save and load reusable grid profiles
- Define standards, unknowns, well names, and notes
- Import and export assay setup CSV files
- Calculate standard curves and unknown concentrations
- Review sortable per-well signal and concentration data
- Export well data as CSV
- Create PDF assay reports
- Organize generated files in the Spotxel Reader workspace under On My iPhone or On My iPad
- Select camera and default microplate grid settings
- Rotate and flip images and grids
- Customize the interface with color profiles and light or dark appearance modes
- Access expanded in-app help and documentation

All analysis features are available in the free version, which includes a small advertising placement. The optional Perpetual License and auto-renewable 3-Month Subscription remove advertising.
