I never would have been able to know that if it wasn’t for this app that tells you what was expired based on the batch code numbers that you see on the bottom of the bottle. I know everyone thinks that it’s cost-effective to finish a product until it’s done even past the expiration date, but you don’t realize that the product starts to change when it is expired. When my dry shampoo started to smell it was over powering and embarrassing to use because the smell was that bad. I had no idea that the dry shampoo was expired. In reality, if you have several products passed its expiration date and you’re up in the air to toss them out you’re probably not going to need to replace all the products that you’re getting rid of. Think about it if you loved the product it never would have reached its expiration date. ### 1/5 — Date is totally made up *2026-07-13, version 2.0.9* The app decoder is so random and decodes whatever you input. I tried to put nonsense words in it and it returned a valid date. Can’t trust this app at all. ### 3/5 — Pretty reliable *2026-07-06, version 2.0.9* correct dates about 7/10 but some were way off by years. Not everything has been expired that’s been reported here. they have the option to let them know and they correct it. ### 1/5 — What happened to the TRIAL promotion? *2026-07-06, version 2.0.9* The trial promotion was 10 seconds. Not one week, not even one day. I was excited to see that something like this exists BUT without first being able to see if this is going to be beneficial for me, let alone how it works, and the results, it’s a waste . ### 2/5 — Subscription *2026-06-18, version 2.0.9* Can I seriously only check one item a day with this thing without a subscription? That’s ridiculous. ### 5/5 — extremely helpful *2026-04-17, version 1.10.5* extremely helpful ### 5/5 — Great *2026-01-18, version 1.9.3* helpful ### 5/5 — Great！ *2026-01-12* Great！ ### 1/5 — This isn’t in English *2018-02-16, version 1.6* And I can’t find a place to change it.
