In case anyone os curious here are the apps I'm actively using for my 日本語の学ぶ (studying of Japanese):
☞ https://apps.apple.com/app/id939540371 Language Drops
☞ https://apps.apple.com/app/id570060128 Duolingo
☞ https://apps.apple.com/app/id290664053 renzo, Inc.'s 辞書 (dictionary)
☞ https://apps.apple.com/app/id1048445761 Kanji Teacher by Christian Rusche
I've one at least one session (five minutes each) of Drops, every single day for 217 days!
I don't thing I have practiced or studied anything that consistently before.
I usually two or three. Sometimes I do one or two while waiting for an appointment or a table to become available in a restaurant. I do extras before going to sleep or before getting up in the morning.
I've also managed to do Duolingo sessions every day for 214 days.
After a couple days of Drops I decided to make another go at Duolingo which I'd tried a couple years back. The five or ten minutes of overhead from Drops alone was too easy to manage, and I figure that different voices, fonts and colors, and content would help me learn the language not just one app's contents.
A typical Duolingo session takes me 10 minutes. But I also have studied the syllabic written form (仮名 — kana). I do those sessions in about five minutes each and I did two of those per day — one for 平仮名の — hiragana, and another for 片仮名 — katana. I wanted to keep relatively in sync for the katakana and hiragana because I've found that learning them separately just muddles them later.
The Duolingo kana sessions are separated into one per row of the goju on 五十音 (50 sounds). I guess I was takin taking about five sessions on each row before advancing to the next. It's a freeform grid of topics, with color highlighting for what you've started and which you've become proficient at. I'm almost completely done with those, and I'm no longer consistently doing those every day.
Those kana modules that remain are just for when I'm in the mood or have a whim. They're most just some of the advanced nuances of kana, like the use of the small っ(vs the regular つ — "tsu") which has the effected transliterated as a doubled consonant sound, like the distinct pause between the k's in "bookkeeper") and the use of little ゃ, ゅ andょfor certain exceptions to the syllabary — like しゃ ("sha") vs. しや ("shi ya") and so on. I was aware of those from previous attempts to learn the language, and they mostly follow some simply patterns. No urgent need to go through the drills on those.
So as I phased past the daily kana study, I've phased in the use of the Kanji Teacher.
