I spend about a half hour per day on it. The first two apps are oriented around five minute sessions. I pause to use the dictionary so I can practice entering hiragana (input method / keyboard) to find the kanji (漢字) which shows similar words, kanji stroke order, and plenty of example sentences (with romaji, kanji, and furigana).

My current lesson streak is just over 90 days long.
