In Simply Learn, by Simya Solutions, you can search for and review over 1000 phrases in over 30 categories. It takes the typical phrasebook app one step further by allowing you to add your favorite phrases to SRS flashcards. Given that its developers also developed Ling, an additional, more comprehensive resource that supports language learning, it seems that Simply Learn is a supplementary app for individuals who need to learn basic phrases for traveling abroad.
The creators don’t seem to have intended for people to use this app to learn a language in its entirety, but rather to support them in memorizing basic phrases for travel. As with Simya Solutions’ other apps, Simply Learn is most helpful for less commonly learned languages, such as Hokkien and Khmer.
Beginners can access the basic cards for free, but the advanced traveler will have to make a one-time purchase to access all the content. If what you truly want is to have a set of phrases under your belt, Simply Learn’s SRS flashcards and native-speaker audio can support you. However, if you are studying a less commonly learned language and want to understand the basic sentence patterns and writing system, check out Ling.
