Frequently asked questions

Everything you need to know about scaling recipes, importing from links or photos, and baking with hands-free timers.

What sources can I import recipes from?

You can paste a link from any recipe website, or from social posts on Instagram, TikTok, YouTube, and Facebook. You can also paste plain text from notes or books, upload up to three photos of a printed recipe, or use the guided recipe builder.

What is the difference between Original view and Recipe view?

Original view displays the saved source page or social post so you can see author photos, tips, and commentary. Recipe view displays the clean Bakers Math table with scaled gram weights, baker's percentages, and step-by-step instructions.

Does recipe scaling change the numbers in the cooking instructions?

Yes. When you change batch size, Bakers Math updates both the ingredient table weights and inline quantities written in the instructions, such as water or yeast amounts.

How does pan-size scaling work?

Pick your original pan and your target pans. Bakers Math compares surface areas and volumes to find the scaling ratio, then calculates the total dough weight and splits it evenly across each pan.

How do inline instruction timers work in Cook Mode?

Cook Mode highlights any time written in your instructions. Tap a duration to start a live timer in the top bar. When time is up, an audio chime and notification alert you while your screen stays awake.

Are the baking calculators free to use?

Yes. All eight baking calculators are free to use without creating an account. If you want to save recipes, scale them, and cook hands-free, you can create a free account.
