New: Auto-count (Beta) that learns from your own counts, trained privately on your device. Plus saved sessions, Files import and a refined Liquid Glass look.
Colony Counter PRO: Laboratory Tool for Microbial Enumeration
Colony Counter PRO is a scientific application for bacterial colony enumeration from petri dish images. Built for microbiologists, lab technicians, and researchers who demand accurate counts, structured workflows, and publication-ready data.
Access & Availability: Colony Counter PRO is a paid application. Free licenses and discounts are available to researchers and institutions in some low- and middle-income countries where microbiological diagnostics are critical for public health surveillance and outbreak response.
ADVANCED COUNTING SYSTEM
• Count up to 20 distinct colony morphologies per plate, each with a custom name and color
• Tap-to-place color-coded dot markers with configurable size, opacity, and outline style
• Erase mode lets you remove individual markers without resetting your work
• Pinch-to-zoom (0.5×–5×) and pan for precise placement on dense plates
• Undo, per-type reset, and full-plate reset options at every step
AUTO-COUNT THAT LEARNS FROM YOU (Beta)
• Personal models: when you finish a plate, the dots you placed teach the app what each of your colony types looks like
• One model per colony type, so you can build a different Auto-count for each medium or organism
• Trained and stored on your device. Your counts are never uploaded or shared, and you can export, import, or delete your models at any time
• Auto-count unlocks once a model has learned from enough plates and proves accurate on plates it has not seen, and it keeps improving as you count
• Plates are detected in your photo and numbered, so you tap the one you want to count; drag or pinch to fine-tune the circle
• Preview detected colonies before accepting — accept all or discard with one tap
• Auto-count is in Beta: always review the result
IMAGE TOOLS
• Import from Photo Library, Camera, or the Files app, with no duplicate copies in Photos and Files
• Crop images to the area you want to count
• Adjust brightness, contrast, and image opacity for difficult plates
• Rotate images in 90° steps — dot coordinates transform automatically
• Choose from multiple background options (grid, black, white, and more)
SESSION & PLATE MANAGEMENT
• Multi-plate sessions for time-course studies and replicate experiments
• Single-plate mode for rapid isolated counts
• Name sessions and individual plates; rename plates at any time
• Session Library archives all past sessions with open, resume, and delete options
• Finish a plate when you are done, and reopen it later to correct it
• Autosave every 30 seconds, with additional save-on-backgrounding for data safety
CFU CALCULATOR & EXPORT
• Integrated CFU/mL calculator: enter dilution factor and volume plated, results update instantly
• Annotated image export: plate image with dot overlay, per-type counts, CFU/mL, and timestamp
• CSV export in two formats — Detailed (per type, per plate) and Summary (totals per plate)
• Save annotated images to Photos or Files, or share directly from the app
• Batch export all plate images at once
DESIGNED FOR REAL LABORATORY WORKFLOWS
Colony Counter PRO was developed with input from practicing microbiologists and is used across research, quality control, clinical, environmental, and educational settings — wherever accurate colony enumeration and proper records matter. The interface uses Liquid Glass, with a toolbar bubble you can slide between tools. New iPhone Duo also supported!
Start counting smarter. Your data deserves better than a tally counter.
• Auto-count (Beta): train models on your own manual counts. They are created and stored on your device, and your data never leaves it.
• Multiple Auto-count models: each colony type gets its own model. Choose the model and the plate, then run Auto-count again for the next type.
• Pick the plate to count: plates are detected in your photo and numbered, so you can tap the one you want and fine-tune the circle.
• Save work sessions and review past sessions at any time.
• Import images straight from Files, with no duplicate copies in Photos and Files.
• New Crop Image tool, next to Rotate.
• Finish a plate more reliably, and reopen a finished plate to correct it.
• New Liquid Glass toolbar with a sliding bubble you can drag between tools.
• Improved stability and appearance.
• iPhone Duo supported
