Shiken Premium is a paid upgrade that unlocks additional features within the Shiken App. Annual and Life Time subscriptions are available and Shiken Premium costs about the same as a large cup of coffee each month (£3.75/month).
Additional features include expanded mindfulness biomes and narrated guided relaxation tracks and music, expanded Challenge options, unlimited notes and photo notes and an exclusive Study Buddy.
You can upgrade to Shiken Premium anytime you like from within the Shiken app.
