About this app

TLC Report — A comprehensive digital solution for pharmaceutical testing laboratories, research institutes, and analytical chemistry laboratories in thin-layer chromatography (TLC) imaging, processing, and documentation.

🔬 KEY FEATURES:

1. Professional Chromatography Image Processing (OpenCV Native):

• Perspective Transform: Completely eliminates distortion and tilting when capturing thin layers with a smartphone camera.

• Adaptive Local Contrast Enhancement (CLAHE): Clarifys blurry areas and hard-to-see chromatographic spots.

• Gamma Correction & Display Filters: Fine-tune brightness and color saturation to clearly identify the color of test spots without distorting the original image data.

• Automatic EXIF ​​Processing: Recognizes and correctly rotates the camera-captured image upon loading.

2. Interactive Marking & Accurate Rf Index Calculation:

• Automatic zoom (Auto-fit) and full view of the thin layer immediately upon image opening.

• Intuitive touch operation to set Baseline, Solvent front, test/standard samples, and sample identification labels.

• Supports smooth drag-and-drop fine-tuning, D-pad tool for pixel-by-pixel coordinate adjustment (±1 px).

• Convenient multi-step undo history.

• Automatically calculates instant Rf values ​​using the standard Pharmacopoeia formula with standard Vietnamese decimal point format (e.g., 0.50; 0.72).

3. Parallel Comparison of Two Blocks (Block A / Block B):

• Flexible management of two thin layer strips in the same work session (comparing test samples and standard samples of medicinal materials).

• Automatically synchronizes spot numbers and Rf values ​​to the detailed data table.

• Integrated keyboard with quick access to specialized characters: °C, μ, μg, μL, λ, α, β, γ.

4. Export Standard A4 PDF Reports:

• Professional A4 layout, completely consistent between mobile and desktop versions.

• Embed sharp images of biomarkers with clear markers and label symbols.

• Integrated Vietnamese font with full and sharp diacritics.

• Supports PDF preview, direct printing, saving to device memory, or quick sharing via Email or Zalo.

5. Completely Offline Operation:

• All image processing and PDF creation algorithms run directly on the device (On-Device).

• No images or test data are sent to external servers, ensuring the safety and security of test report information.

6. Completely Ad-Free & Support the Author:
• 100% clean app, free from any banners, pop-ups, or video ads that interrupt your work.

• Includes a voluntary In-App Purchase feature to "Support the Author" to help fund the app's maintenance and development.
Process thin-layer chromatography images, align angles, calculate Rf values, and export a standard A4 PDF report.
