SpecSwap

SpecSwap helps home cooks and bakers replace missing ingredients with substitutions that preserve taste, texture, and chemistry. Instead of generic “use yogurt for sour cream” tips, it asks what you’re making, your constraints (vegan, gluten-free, low-sodium), and what you actually have on hand. It then outputs ranked swaps with exact ratios, method tweaks (mixing order, hydration, bake time), and risk warnings (e.g., “will brown faster,” “may curdle,” “won’t whip”). The app includes a pantry list you can maintain manually (no gimmicky scanning required) and learns your preferences over time. It’s a mobile app with a lightweight web companion for saving and sharing substitution cards. Realistically, this wins only if the guidance is consistently reliable; sloppy advice will get uninstalled fast.
