I’ve been asking them to implement this since I got the Dex camera in October 2025. The languages have many mistranslations, and there is no way for native speaking parents to submit direct feedback to improve it. This feels lazy and is a disservice to the families that are putting their trust on Dex to teach their child their native language and specific dialect. Nearly half of the Puerto Rican Spanish words that Dex is teaching my child are actually not commonly spoken in Puerto Rico. This has not improved in seven months since we started using Dex. If you implemented a tool in the app for parents to directly provide feedback about the words the child encounters during the activities, you would have a far more effective product in your hands. Moreover, there’s too much reliance on Gen AI for content generation. The songs that come up sometimes are honestly terrible. Hire a content creation team of ARTISTS and pay them their dues. Leverage your user base. It’s not too much to ask, and the product will be far better for it.
I have 2 Dex cams for my 2 kids and they both love it. It's interactive, fun and helps reinforce the language they're learnin at their immersion school. A couple nits: I wish the silver button on the side of the screen did not so easily turn off and on and sometimes the kids accidentally turn it back on when they are trying to turn it off then screen drains the battery. The app is also not always up-to-date or maybe it’s usually by the way it’s not as intuitive. i’ve also noticed that when I tried to add flash cuts for one kid that automatically shows up in the profile of the other kid but my kids are a different ages and I’m not ready for one of them to have the same flashcards topics available as the other because of the age difference in what they’re learning in class. Not a big deal but I'd like to customize. I know this an early version and I would still highly recommend this as my kids are engaged in the photo taking, stories, and love showing it to friends and family!
I got our first Dex for my my 5 year old on a whim after seeing an instagram ad that showcased its killer app feature of pointing at anything, recognizing it, and unbelievably teaching about it in one of several language options. I can confirm that it delivers on that promise and more. After the novelty of taking pictures wears off, the Dex also has a well-curated set of activity options that extend language learning with your kiddos (and yourself if we are being honest). We have two now and my kids love it! Get it and you won’t be disappointed!
