Drops is a language learning app that focuses on teaching vocabulary through quick, visual-based games. The idea is to make learning feel more like playing, with short sessions you can fit into your day. Instead of grammar-heavy lessons, it leans on matching words with pictures, swiping, and tapping to help words stick in your memory. The app covers over 40 languages, from common ones like Spanish and French to less common ones like Hawaiian and Ainu. You get common, everyday words and phrases to start with—things you’d actually use in conversation. It’s built for people who want to learn at their own pace, and there are features like reminders and streaks to keep you coming back. Drops keeps lessons short—usually five minutes—so it’s easy to squeeze in some learning while waiting for coffee or riding the train. There’s a free version with ads and limits on daily use, or you can pay for Premium to get rid of ads, unlock all content, and use it offline. Overall, it’s not going to teach you complex grammar or how to hold a full conversation right away, but if you’re looking to build your vocabulary in a fun, no-pressure way, it does the job.
- 12.ThaiPod101's Live YouTube Channel
Learning a new language is hard, you need a lot of repeated exposure to the same words to make them stick. Here's the trick I use. I open ThaiPod101's live channel and let it run in the background while I do something else. For example, I can have it open while cooking dinner or tidying up. Even if I look at the screen only occasionally, I still get the benefits of being repeatedly exposed to Thai vocabulary. This works particularly well in combination with other learning methods. If you have a smart TV or a Chromecast, you can even play it on your TV instead of regular TV channels. The channel runs 24/7 and replays ThaiPod101 lessons.
