Yes, as the name of the app implies, you genuinely learn all of hiragana and katakana with these apps in two hours. Four hours in total. I used these apps, and I can now fluently read hiragana and katakana fast and this was the best starting point ever. I would recommend after completing both the courses, review a hiragana/katakana chart every day, and maybe read some furigana children’s books like momotaro. Then practice writing them with correct stroke order. You can find practice pages online!
