Hi Product Hunt, I'm Ali, the solo developer of Pofu.

I built it after watching friends quit calorie apps the week they missed a day or the scale jumped before their period. Most trackers treat both as failure.

What Pofu does differently:

• Up to 2 grace days a month protect your streak automatically

• With optional cycle awareness, Pofu tells you a luteal-phase jump may be water, and adds a small luteal allowance (about 5%, 80 to 150 kcal) you can turn off

• Photo logging shows a confidence score, so you know when an estimate needs a check

• Barcode, search and manual logging are free; cycle data stays on the device

It's iPhone only, new, and has very few ratings, so honest feedback helps a lot. What would make you stick with a calorie tracker?
