iPhone
Bake perfectly at any altitude.
If you've ever moved to Denver, Calgary, or Mexico City and watched your favorite cake recipe collapse in the oven, you know the problem. Lower air pressure makes baked goods rise too fast, dry out, and fall flat. Standard sea-level recipes just don't work.
AltiBake fixes that — automatically.
USES YOUR iPHONE'S BAROMETER
Every modern iPhone has a barometric pressure sensor. AltiBake reads it in real time to detect your altitude and the exact pressure right now. That's more accurate than altitude charts because today's pressure matters as much as your elevation. A low-pressure system can make your high-altitude problems worse.
ADJUST ANY RECIPE IN SECONDS
Pick a category — cakes, quick breads, yeast breads, cookies, pastries, muffins, or pies. Enter your sea-level recipe. AltiBake shows you exactly what to change:
• How much extra flour to add (per cup)
• How much sugar to remove
• How much liquid to increase
• How much to reduce baking powder or soda
• How much hotter to set your oven
• How many minutes to subtract from the bake time
• Whether to add an extra egg
Every change comes with a plain-English explanation of why.
Have the recipe on a website or in Notes? Paste it and AltiBake fills in the amounts for you. You review them before adjusting. Amounts in cups, spoons and millilitres are read; grams you enter by hand.
QUICK REFERENCE BUILT IN
A side-by-side table shows adjustments for every altitude zone, with your current zone highlighted. Read about why altitude affects baking. Get tips for high-altitude techniques. See the boiling point of water at your altitude (matters for candy and jam). Reference altitudes for major cities.
SAVED RECIPES
Save your adjusted recipes — AltiBake remembers the altitude where you saved each one. If you travel, AltiBake automatically recalculates for your new altitude.
WIDGET INCLUDED
Add the AltiBake widget to your home screen for at-a-glance altitude and quick adjustments.
SPANISH AND ENGLISH
Full Spanish localization for bakers in Mexico, Colombia, Ecuador, and beyond.
PRIVATE BY DESIGN
AltiBake works entirely on your device. No accounts, no tracking, no servers, no internet required. We don't see your altitude, your location, or your recipes.
ONE-TIME PRICE
A one-time purchase unlocks unlimited recipe adjustments — forever. This is a one-time purchase, not a subscription: no auto-renewal, no recurring charges. The free tier includes one recipe adjustment per day, saved recipes and the full quick reference.
Made for bakers who refuse to settle for a sunken cake.
