New Open Food Facts mobile app for Android and iPhone - Codename: "Smooth App"

Latest commit deployed to App Stores: (August 4th 2022) https://github.com/openfoodfacts/smooth-app/releases/tag/v3.6.0

A new Flutter application by Open Food Facts. You can install it on Android or iPhone/iPad. Note that a internal development build (Android or iPhone/iPad )if you'd like to use the results of your PRs quicker.

Smoothie. We pioneered the collaborative scanning app in 2012. With this experimental app, we’re reinventing it from the ground up, and this time, it’s personal.

You get:

• a scan that truly matches who you are (Green: the product matches your criteria, Red: there is a problem, Gray: Help us answer you by photographing the products)
• a product page that's knowledgeable, building on the vast amount of food facts we collect collaboratively, and other sources of knowledge, to help you make better food decisions

You can:

• scan and compare in 15 seconds the 3 brands of tomato sauces left on the shelf, on your terms.
• get a tailored comparison of any food category
• set your preferences without ruining your privacy

Criteria you can pick:

• Environment: Eco-Score
• Health: Additives & Ultra processed foods, Salt, Allergens, Nutri-Score

Presentation

This new mobile application aims to showcase Open Food Facts's power to a broad range of users through a smooth user experience and sleek user interface.

Smooth-app is developed in parallel to the openfoodfacts-dart plugin, which provides a high level interface with the Open Food Facts API. Every new interaction with the API should be implemented in the plugin in order to provide these new features to other developers.

V1 Roadmap (Shipped on June 15th 2022 for Vivatech)

• [x] We should be able to ship the Smoothie code to the main listing on Android and iOS
• [x] The app should be able to scan very well
• [x] Minimal Road to Scores (you should be able to get Nutri-Score and Eco-Score on any unknown/uncomplete product in 2 minutes, using editing and/or product addition
  • [x] Initial photo taking, good ingredient extraction, Nutrition input, Category input (TODO)
• [x] Database migration for existing Android and iOS users (minimum: history, credentials, if possible with allergen alerts, lists)
• [x] A Welcome scan card that can broadcast a message from the Open Food Facts team per country/language (Tagline)
• [x] On-page photo refresh capabilities (Not working well)
• [x] V1 tracking

V1.1

• [x] Allow to switch languages
• [x] Allow to expand search results to the world

Next

Scanning

• [ ] Ensure no one complains about not being able to scan
• [ ] Add offline scanning to ensure results in all conditions

Contribution

• [ ] Speedup image upload
• [ ] Improve the scan experience when Nutri-Score and Eco-Score are not present (some people don't click on the card even if fully unhelpful)
• [ ] Offer a faster editing system for power users (and potentially all)
  • [ ] Add power edit mode that concatenates all the editable things for faster contribution
• [ ] Add a list of things to do contribution wise on the product (via Knowledge Panels or natively), or introduce a "Raw data" mode for power contributors

Value added in browsing

• [ ] Clarify the alternative product proposition
• [ ] Reintroduce the portion calculator

Gamification

• [ ] Add the number of contributions when logged in
• [ ] Integration with openfoodfacts-events

Settings

• [ ] Revamped settings that are less cluttered, and can make way in the future for things the user will go see more often.
• [ ] Personalization system that does not feel weird during setup, where people understand consequence, and where ranking match their expectations even in stretch cases (lack of data on some product, selecting Nutri-Score and all Low-in Nutrients…), where red-lines are clearly shown (allergens) with potential caveats, where solutions are proposed and warning issued in case of lack of data.

Misc

• [ ] Fix HTTP header and contribution comments

Building

Internationalization

• Translations of the interface are managed using the new Flutter internationalization introduced in Flutter 1.22.
• New strings need to be added to lib/l10n/app_en.arb and the corresponding translations can be added through CrowdIn. Do not edit the other app_*.arb files as they will be overwritten by CrowdIn.
