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 when you want stronger checks, saved products, reminders, and long-term product tracking.
Will links from the website open the app?
If Universal Links or Android App Links are enabled on the installed app, supported lotdate.com links can open the app directly. Otherwise they continue to the 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 save the product, edit dates when needed, and set reminders before expiry.
