ShrimpCount is the fastest way to count shrimp nauplii (baby shrimp / seed) in a sample tray — right on your phone, in seconds. No account. No internet. No cloud. Just open the app and count. Point your camera at a sample tray, capture a photo, and ShrimpCount's on-device computer-vision algorithm returns an instant count. Everything runs locally on your device — your photos and counts never leave your phone. BUILT FOR HATCHERIES Whether you're stocking tanks, grading batches, or reconciling a sale, ShrimpCount gives you a fast, repeatable count without a manual tally. • Instant on-device counting — no waiting on a server • Works completely offline — perfect for the pond bank or the hatchery floor • Label every count with a batch name (Tank A, Nursery 2, Pond 3…) • Full history with the photo, batch, date, and count — saved privately on your device • At-a-glance stats: total counts, total seed, and average per count • Share any result (with the photo) via Messages, WhatsApp, email, and more PRIVATE BY DESIGN There is no sign-up and no login. ShrimpCount does not collect your name, email, or any personal data, and it never uploads your photos. All image analysis happens on-device. HOW IT WORKS 1. Tap "Start Counting" and photograph your sample tray. 2. Tap "Count Shrimp" — the count appears in seconds. 3. Review it any time in History, or share it with your team. TIPS FOR THE BEST COUNT • Use a white or light-coloured tray for contrast. • Spread the sample out so nauplii don't overlap. • Use even lighting and avoid strong shadows. ShrimpCount is free to use.
