Family-made in Canada 🍁

We make small apps, carefully.

Guinea Pig SD is a Canadian family indie studio, just the two of us. Bouncer, Nyamly and Just Zones are all live on the App Store.

Nyamly: Calorie & Food Scanner

A calorie and nutrition tracker that admits what it doesn't know. Scan a barcode, snap a photo or type a meal; when a figure was never published, Nyamly shows it as unknown, not zero.
