Capture
Dip the strip in your sample. Wait the reaction time. Place strip + manufacturer ramp in the same shot. Auto-capture detects when steady, fires automatically.
Don't guess.
Measure.
Read any colorimetric test strip with your phone. AI Vision + Cheung 2004 color correction + 5 quality gates — ±5% accuracy, no hardware.

Analyze
AI Vision extracts RGB from each ramp patch and the strip pad. Engine applies Cheung 2004 polynomial color correction — strips out camera + light bias. Lab-space interpolation.
Verify
5 quality gates: AI confidence, ΔE94, engine ⋈ AI cross-check, ramp monotonic, strip in-range. All pass to record. Any fail rejects, asks for retake.
Color measurement isn't a guess. Software shouldn't guess either.
Published science
Cheung et al. 2004 — "Polynomial-based modelling of camera response." An 11-coefficient polynomial regression strips camera color errors. Same algorithm as the academic reference; we didn't make it up.
Cross-validation
Engine (classical color science) + AI Vision (image model) compute the same strip via two independent methods. If they disagree, the user never sees a result. A trust layer single-method readings can't provide.

Aquarium / pool / hobby use only. Not for accredited lab compliance. Not FDA / CE.
Turn physical test strips into a digital platform.
Chemical reagent manufacturers, pool brands, and water testing labs partner with StripVision to eliminate customer visual guessing. Deliver lab-grade mobile scanning apps under your own brand with packaging QR code quick-scan.
Add Your Brand into StripVision
We onboard your proprietary test strip directly into the official StripVision app. Thousands of hobbyists, pool owners, and water quality technicians select your brand from the strip picker.
Turnkey White-Label App
Branded iOS & Android mobile companion applications published under your developer accounts. Includes custom UI styling, packaging QR quick-scan, and tailored chemical dosage recommendations.
Custom Reagent Calibration & Packaging QR
We mathematically digitize and calibrate any test strip portfolio. Adding a smart QR code to your bottle packaging lets customers read strips instantly with zero manual configuration.
Batch QA & Cloud API
Compensate for batch-to-batch chemical variations in reagent manufacturing dynamically via cloud calibration profiles. High-throughput REST API for municipal utilities and field fleets.
Quick answers.
Which test strip brands work?
Any brand whose box ramp is visible in the photo works. We've tested heavily with API Master Test, JBL ProAquaTest, Tetra EasyStrips, Hach DPD, Lovibond, Sera, and Pool Master.
I have a different or custom test strip, can you add it?
Yes! StripVision's optical engine can be calibrated for new strip layouts and custom chemical reagents. To add your test strip to the app, build a brand-specific calibration, or request higher enterprise quota, contact us at destek@takil.app.
Do I need hardware or special lighting?
No. Standard indoor lighting (LED ceiling, daylight) is enough. The pipeline strips camera + light bias with polynomial color correction — you just frame the strip + ramp together.
What does ±5% accuracy mean?
For 3 validated chemicals (free chlorine, chlorine dioxide, pH), against lab reference strips, results land within ±5% of true. The other 6 are still in calibration — the app explicitly labels each as "validated" or "placeholder" so you see exactly which.
Where do my measurements go?
Nowhere. Your full history lives in your phone's local AsyncStorage. Delete the app or tap "Clear all measurements" to wipe instantly. Photos pass briefly through our Vercel edge proxy for AI analysis, never stored anywhere.
Which devices does it work on?
iOS 16+ and iPhone 11+ recommended. Download directly from StripVision on the App Store.
