AltiBake: Altitude Baking

Bake like you are back at sea level. Above about 3,000 ft the air is thinner and drier, so cakes rise fast and sink, cookies spread, and bread over-proofs. AltiBake tells you exactly how to change a recipe for the elevation where you live.

Set your elevation once and AltiBake shows the five things that matter, each as a clear starting range you can dial in.

What you get:
- Set your home elevation one time. Every adjustment updates to your kitchen.
- See what to change: flour, leavening, sugar, liquid, and oven temperature.
- Read the why behind each tweak, in plain language.
- Switch between cake, cookie, and yeast bread modes for guidance that fits the bake.
- Save your go-to recipes and reopen them already adjusted.
- Export an adjusted recipe as a PDF or CSV to print or share.
- Work in metric or imperial: feet or meters, Fahrenheit or Celsius.
- A change-by-elevation chart shows how each adjustment grows as you climb.

Free and one-time:
AltiBake is free for the core adjuster and the guide. One optional purchase, paid a single time, unlocks the cake, cookie, and yeast modes, your saved recipe library, and PDF and CSV export. No subscription, no account.

Honest by design:
Altitude baking also depends on your oven, humidity, and the recipe. AltiBake gives ranges to dial in over a few bakes, not promises.

Private by design:
