About Roméo Apps

Who is behind the apps

Roméo Gambino designs, builds and supports each app himself and publishes them on the App Store under his own name. There is no studio, no investor and no advertising network behind the catalogue.

The apps cover working memory training (Dual N-Back), quitting vaping (PuffOff), nail-biting habits (NailSafe), AI photo prompts (LarpGPT), offline preparedness (Surv), voice practice (VocalMaxx) and mental arithmetic (Numvolt).

How the apps are built

Every app is native to iPhone, written in Swift and SwiftUI, and works without an account. Data stays on the device unless a feature says otherwise in its privacy policy. Prices and in-app purchases are shown by the App Store in local currency before any confirmation.

This website describes what each app does. It publishes no ratings, no user counts, no medical claims and no promise of results.

Sources and editorial rules

The guides cite public references such as peer-reviewed studies identified by DOI, public health services and government preparedness guidance. Each guide lists its sources at the end. Texts in languages other than English and French are translations of the product pages and are reviewed with AI assistance.

How the guides are written

Each guide is written for this site rather than assembled from other pages, and is drafted with AI assistance and reviewed before publication. Claims that depend on research are checked against the cited source, and every DOI listed at the end of a guide is verified against the official DOI resolver before it is published. Where the evidence is contested, the guide says so rather than picking the more flattering answer.

Guides about health topics describe what published guidance and peer-reviewed work report. They do not diagnose, treat or replace a professional, and each one says when to consult someone.

What this site will not publish

No ratings or star counts the developer cannot substantiate. No user numbers. No named researcher presented as endorsing an app. No promise of a result, a timeline or a recovery date. No before-and-after imagery suggesting an outcome the apps cannot deliver. These rules apply to the App Store pages, the apps themselves and this website equally.

Corrections

If something here is wrong, write to [email protected] with the page address and what is incorrect. Factual corrections are made to the page itself and the update date changes with the next publication. Corrections are welcome on the guides in particular, since they cite external sources that can change.

How this is paid for

The site carries no advertising, no affiliate links, no sponsored content and no tracking or advertising cookies. It exists to describe the apps and to host their privacy, terms and support pages. The apps themselves are funded by their own downloads and in-app purchases, which the App Store displays in your local currency before any confirmation.
