iOS app
Move from one-off checks to a real beauty inventory workflow
The website is built for fast search traffic and quick answers. The iOS app is built for repeat use: save results, track opened products, retry with stronger AI help, and keep your skincare, makeup, sunscreen, and fragrance decisions in one place.
Why install the app
Save every result
Keep brand, batch code, production estimate, and lookup context instead of repeating the same check later.
Track opened products
Use the decoded timing together with your open date, PAO, and product condition for safer rotation.
Handle harder lookups
Use stronger AI assistance when a code is faint, unusual, or not recognized by the quick web checker.
Manage more checks
The app is the better workflow for frequent users who compare sellers, organize backups, or maintain a large collection.
Best web-to-app workflow
- Search or land on the brand page from Google.
- Run a quick web check or read the brand guidance.
- Install the app when you want saved history, repeat checks, and long-term inventory tracking.
App download FAQ
Does the app replace the website?
No. The website is still best for quick one-off checks from search. The app is better for repeat use, saved history, and opened-product tracking.
Will links from the website open the app?
If Universal Links are enabled on the installed iOS app, supported lotdate.com links can open the app directly. Otherwise they continue to the App Store or web page.
Why use the app after a successful web result?
A decoded date is only useful if you remember it later. The app lets you keep the result and make product-rotation decisions over time.
