Honest Review

I have been searching for a batch code checker like this one since long. I have used many but not perfect. I find it fantastic for me

Great tool for consumer fragrance industry

I work in consumer fragrance and this app is currently the most efficient source on the market for finding out when a product was made. A couple tweaks I would like to see:
1) having a keyboard in app that displays numbers and letters on the same keyboard set would drastically speed up the process when having to process large batches of product!
2) a camera scanner for batch codes would be bizarrely helpful—not sure if that’s possible but it would be amazing if it were!!

Great app!! I use this nearly every day.

Your firsthand experience makes this feedback especially valuable to us.

쓰레기같아요

유료결제까지 했는데 먹통될때가 많아요 . 오히려 웹사이트에서 무료로 조회하는게 더 잘됩니다. 어플이 오류가나도 신고하거나 문의할 곳도 없어요 쓰지마세요

Response from developer

유료로 이용해 주셨는데 만족스러운 경험을 드리지 못해 죄송합니다. 말씀해 주신 상황은 정상적인 이용 상태가 아닙니다. 앱의 설정 → 의견 보내기에서 브랜드와 배치 코드, 이용 상황을 알려주시면 자세히 확인하겠습니다. 결과 화면의 피드백 보내기에서도 바로 제보하실 수 있습니다. 문의 경로에 대한 의견도 중요하게 받아들이고 있으며, 더 안정적으로 이용하실 수 있도록 계속 개선하겠습니다. 문제가 해결되어 이용 경험이 달라진다면, 이후의 경험도 함께 고려해 주시면 감사하겠습니다.

Amazing

I love this app. I was able to clear out my medicine cabinet full of hair products because they were all expired. 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.

Date is totally made up

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.

Response from developer

Thank you for raising this. LotDate is designed to decode genuine batch codes printed on product packaging using brand-specific formats, and results depend on selecting the correct brand and entering the printed code accurately. We’re improving how unsupported inputs are identified. If a real product code gives an unexpected result, please tap ‘Not accurate? → Send feedback’ so we can verify it directly and improve the experience for you.
