Can I try before I subscribe?
Yes — Bronze is free, with no card needed: one instrument on its beginner path, 5 lessons a month and 10 AI feedback sessions a month. Voxstrum is in closed testing on Google Play right now;
join the test group to get in early, and you'll get 6 months of Multi Platinum free when we launch.
How does billing work?
Nothing is on sale yet. When Voxstrum launches, subscriptions will be bought and managed through Google Play, monthly or annually, and you'll be able to cancel at any time from your Google Play subscriptions. Annual plans are charged as one yearly payment. Purchases are switched off in the test build.
What's the difference between Gold and Platinum?
Gold gives you all 10 instruments, the full lesson curriculum and 100 AI feedback sessions a month. Platinum adds Studio — Write, Record, Arrange and Release — where you can dictate lyrics, record takes, turn a sung or played melody into editable sheet music and export MusicXML or MIDI, and it raises the allowance: Platinum includes 200 AI feedback sessions a month.
How does Multi Platinum work?
Multi Platinum is for a teacher or parent. For you, it includes 100 AI feedback sessions a month (fewer than Platinum's 200) plus Platinum's Studio, MusicXML and MIDI export and all instrument skins, and it adds a teacher dashboard with up to 5 student seats. Your students join on the free Bronze plan — one instrument on its beginner path, 5 lessons a month and 10 AI feedback sessions a month. You can see their sessions and scores, assign lesson plans and Play Along tracks (assigned tracks play on their free account), and message them in a moderated in-app chat. Students under 13 need a guardian's consent before they can be linked. Student seats aren't extra copies of your plan, so a learner who wants the full curriculum needs their own subscription.
Can I switch plans?
Yes — once plans are on sale you'll be able to upgrade or downgrade through Google Play.
What is your refund policy?
Refunds are handled by Google according to Google Play's policies. Contact
