Calorie counter apps compared: tracking and advertising per the App Store
This overview sets nine calorie counters for the iPhone side by side, using only a source anyone can check: the privacy details each development team publishes on its own App Store page. No rating, no price comparison, nothing about features.
TellerBuddy is made by BYTEPOTATO UG (haftungsbeschränkt) in Göttingen. We are in the table ourselves, and we state what our own entry does not rule out.
Tracking and third-party advertising per the App Store
Based on the privacy details each development team publishes on its product page in the Irish App Store (self-reported, not verified by Apple). “Yes” means the team states there that data may be used for this. In brackets are the data categories listed under the tracking entry. Retrieved on 27 October 2026; the source column links to the product page.

TellerBuddy collects data too. According to its own listing in the Irish App Store, the following may be linked to your identity, each for App Functionality: Health & Fitness (Health, Fitness), Contact Info (Email Address, Name), User Content (Photos or Videos, Customer Support, Other User Content) and Identifiers (User ID). Not linked to you may be Usage Data (Product Interaction) for Analytics, and Diagnostics (Crash Data, Other Diagnostic Data) for App Functionality. TellerBuddy lists no data used to track you. Without an account, your diary, profile and weight stay on your device; the details are in the privacy policy.
How to read the table
- “Yes” only means: the development team states that data may be used for this. It says nothing about how often or to what extent.
- “No” means: the entry does not mention it. It does not mean the app handles no data at all; TellerBuddy, too, has data categories that may be collected, see above.
- The details change without notice. The current App Store entry is always the one that counts.
Statements by the providers on streaks
The Lifesum Help Center describes streaks: a streak is the number of days in a row on which food was tracked in the app (source, retrieved on 27 October 2026). Provider: Lifesum.
We say nothing here about the other apps, because we have not read a statement by the provider itself on the retrieval date. That does not mean there is none. TellerBuddy has no streaks, badges or points.

Frequently asked questions
Which calorie counters state tracking on the App Store?
The table above shows it, per app with source and retrieval date. It changes when the development teams change their details.
Where do the details come from?
From the “App Privacy” section of each app’s Irish App Store page. These are self-reported by the development teams; Apple does not check them.
How up to date is the comparison?
It carries the retrieval date 27 October 2026. We check the details against the App Store with a script before we change the page.
Why are prices and features missing?
Because they change by country and version, and we cannot set them side by side in a verifiable way. The table is limited to what anyone can read for themselves.
