Logging Food
Piehole makes it fast to log what you eat. Whether you know the exact nutrition facts or just the name of a dish, there’s a path for you.
Searching for food
Tap + Add Food on the Today tab and start typing. Results appear instantly from three sources:
| Source | What’s in it |
|---|---|
| Your Foods | Foods you’ve logged before, ranked by how often |
| USDA Foods | 7,800+ common foods from the USDA SR Legacy database |
| Open Food Facts | Packaged products worldwide (barcode database) |
Search results are grouped by source so you can see where each item came from. Your personal foods always appear first.
Tap any result to pre-fill the name, calories, and macros. Review the values, adjust the serving size if needed, and tap Add.
Quick Add
When the search box is empty, a scrollable list of your recently logged foods appears below. Tap any item to log it again instantly — no searching required.
This list updates as you eat. If you have the same breakfast every day, it’ll always be right there.
Barcode scanning
On iOS, tap Scan Barcode in the Add Food flow. Grant camera permission when prompted, then point the camera at the barcode on a food package.
Supported formats: UPC-A, UPC-E, EAN-13, EAN-8.
Piehole checks your personal library first, then looks up the product in Open Food Facts. If it’s found, nutrition data pre-fills automatically. If not, you can enter it manually and it’ll be saved to your library for next time.
Barcode scanning is not supported on web (browser limitations with linear barcodes). Use search instead.
Editing entries
To edit an entry you’ve already logged, tap it in the Today tab’s food list. You can change the name, calories, macros, or serving size. Tap Save to update it.
Deleting entries
Swipe left on any entry in the Today tab to reveal a Delete button. Tap it to remove the entry from your log.
Deleted entries are gone immediately — there’s no undo, so double-check before confirming.
Your personal food library
Every time you log a food, Piehole saves it to your personal library. The next time you search for that food, it appears under Your Foods at the top of results.
The more you log something, the higher it ranks in your library. Frequently eaten foods float to the top automatically — you shouldn’t have to scroll past things you never eat.
Your library is completely private. Foods you log are never shared with other users.
Manual entry
If a food isn’t in any database, type the name and calories manually. You only need the calorie count — protein, carbs, and fat are optional. Tap Add and it’s logged.
The entry gets saved to your library, so you only have to enter it once.
