Spotxel® Reader vs PlatePad

Spotxel® Reader is a free, feature-complete app for image-based microplate-reader workflows and colorimetric assay analysis. Use Spotxel® 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. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

PlatePad is a fast, focused way to track multi-well plates at the bench — no spreadsheet, no paper notebook. CREATE ANY FORMAT 6- to 384-well grids, configurable gel lanes, 8-tube PCR strips, petri dishes, and T-flasks. Save any layout — including which treatment goes in every well — as a reusable template for routine experiments. LOG TREATMENTS AT A GLANCE Tap a well to name what's in it. Every distinct treatment gets its own color automatically, so a full plate reads at a glance from across the bench. Mark wells treated with one tap. TIMERS THAT NOTIFY YOU Start a countdown from any plate — quick presets or a custom duration — and get notified the moment it's done. Never lose track of an incubation or wash step again. BUILT-IN LAB CALCULATOR Solve dilutions (C1V1=C2V2) or hemocytometer cell counts without leaving the app, including how much stock and diluent to combine for a target seeding density. NOTES AND MORE Keep plate-level notes for observations about the whole experiment. Archive old plates instead of losing them. WORKS EVERYWHERE A responsive layout that works on iPhone, iPad, and in landscape — the plate map switches to a side-by-side view on larger screens so dense 96- and 384-well plates stay easy to read. FREE TO START Track up to 3 active plates at no cost. PLATEPAD PRO Unlimited active plates and CSV export for every plate, with monthly, yearly, or one-time lifetime purchase options. No account, no login required — your plate data stays on your device. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
