Every recipe, sized to the mold in your hands. New: Molds. Pick from a library of popular molds or save your own, and Soaper resizes your recipe's oils to fill it — no math, no guesswork. Capacities come from real, sourced measurements, and you decide how much room to leave for a tall swirled top. Your mold then rides along with the recipe, so you always know what you're pouring into. Deleted a recipe, batch, ingredient, or blend by mistake? It now waits 30 days for you in Settings, under Data Management. Restore it in a tap — one item, or all of them at once. Now you can add video to your batches. Capture the trace, the pour, or the first cut and keep it right alongside your photos and notes, so every batch tells its full story. Water alternatives get their own library. Browse milks, teas, coffees and more, each with its prep and substitution notes, right where you'd expect to find them. Plus a more reliable release: we strengthened stability across the app and polished countless details throughout. Thanks for being part of the Soaper community.
