I believe conversational Tagalog should be easy to learn and that you can have fun doing it.
You already know 50% of it!
The course makes heavy use of Taglish, i.e. Tagalog + English, which is commonly spoken in the Philippines. This will allow you to quickly engage with local speakers in a confident manner.
I hate long lists of verbs, adjectives and nouns to learn. This is the most ineffective way of learning the basics: it's slow, boring and painful. The best way to learn a language is to start speaking it. This is what I focus on.
The goal of this app is to build your confidence and get you beginning to speak and converse with Filipinos. The great thing about Tagalog is that generally any attempt to speak Tagalog is met with great enthusiasm and a big smile from the recipient even if you make a mistake and sound silly. You won't be judged for making mistakes so relax and start making some!
Filipinos very often speak Taglish, this is a combination of Tagalog and English though without formally defined rules.
