Professional-grade unit conversion, recipe scaling, ingredient substitution, and culinary reference tools — all offline, all private, all in one beautifully designed app.
Seven purpose-built tools, each designed to the standard of a professional kitchen — not a hobbyist app.
Convert between volume, weight, temperature, and pan sizes using authoritative densities sourced from King Arthur Baking, USDA, and America's Test Kitchen. Over 200 ingredients with density ranges and source provenance.
Build recipes from scratch and scale them to any serving size. Non-linear scaling automatically adjusts leavening agents, salt, and spices — not just a simple multiplication.
Scale any recipe from ¼× to 10× with professional heuristics. Leavening is reduced 10–20% at 3× scale and above, matching CIA and King Arthur standards. Warnings surface automatically.
Find tested substitutions for hundreds of ingredients — dairy, fats, flours, sweeteners, eggs, and more — with ratio guidance and notes on how each substitute affects texture and flavor.
Run multiple named timers simultaneously. Local notifications fire even when the app is in the background — no internet required, no account needed.
Nine professional reference tools in one place: high-altitude baking, sugar stages, meat temperatures with carryover, convection conversion, pan size substitution, baker's percentages, and more.
Save, organise, and revisit your scaled recipes. All data is stored locally on your device using encrypted UserDefaults — never uploaded to a server.
The Pro Tools tab brings the knowledge of a culinary school textbook into your pocket — interactive, precise, and always offline.
Kitchen Converter Pro is built to run on your device. No analytics. No advertising SDKs. No account system. No server-side collection.
We do not collect names, emails, phone numbers, location data, financial data, health data, contact lists, photos, microphone input, or user files.
Conversion inputs, saved recipes, notes, favorites, and app settings remain on your device unless you explicitly choose to share something yourself.
There is no cross-app or cross-site tracking, no IDFA-based advertising, and no third-party analytics or ad SDKs.
Timer alerts are scheduled on-device after permission is granted. They do not rely on a remote server or third-party notification service.
When you copy a result, the app writes to the system pasteboard at your request. It does not read from your clipboard.
Because the app does not process or sell personal data, its privacy posture is simple: your information stays with you.
Every policy document from the Markdown source has been surfaced as part of the site. Contact support for app help, bug reports, missing ingredients, or attribution corrections.
