Tortio: cake calculator

Tortio is a cake recipe calculator built specifically for cake makers — amateur or pro. Open a recipe, change the diameter or target weight, and every ingredient rescales automatically. Key features: • THREE SCALE MODES — Sponge & cream scale by volume (d²×h), icing & syrup by area (d²), decor stays fixed. Mathematically correct, not just × ratio. • MULTI-TIER CAKES — Each tier has its own size and ingredients. Perfect for weddings, anniversaries, big celebrations. • PRESET SECTIONS — Sponge, cream, filling, coating, ganache, syrup, mousse, meringue, glaze, decor. Add your own custom types. • SHOPPING LIST — One tap, all ingredients summed up. Take it to the store. • PDF EXPORT & SHARE — Send a clean technological card to a colleague or print it out. • COOK COUNTER — Track how many times you've baked each recipe. • PHOTOS, RATINGS, TAGS, NOTES — Organize your recipe collection. • OPTIONAL CLOUD BACKUP — Sync via your own Google Drive (private, only you can see it). Or stay 100% offline. • FREE — All current features are free to use. No ads, no analytics, no tracking. Privacy first: all your recipes live on your device. Cloud backup uses Google Drive's app-private folder — invisible even to other apps. We have no servers and never see your data. Built by a confectioner-friendly developer for real kitchen use. Open source on GitHub. In short: recipe rescaling, cake weight calculation, and a sponge calculator for bakers — all measured in grams. Tortio is for you if: - You need a cake calculator in grams: scale from 22 cm to 18 cm - You bake tiered cakes and hate doing math twice - You want a fast offline cake calculator, not yet another bloated recipe app - You care about ingredient ratios, not generic "1 cup of X" Open to feedback — write to [email protected] or open an issue on github.com/ShadowOfTime1/tortio.
