Frequently asked
Why lifetime?
Because some of us are done renting software we use for a decade. If you're like that, I built this tier for you. First 100 seats only — after that, subscriptions are still here, but lifetime is done.
What if I haven't played in 10 years?
Start at level 1. Nothing here assumes current chops, but nothing patronizes you either. The curriculum is built for adults — no cartoon owls, no "you're on fire!" popups.
Do I need to practice every day?
No. Streaks are off by default on the returner tier. Practice three days one week, one day the next — it all gets measured the same way.
What if Fifths shuts down?
Fair question. If the company folds, I'll open-source the app and ship a downloadable offline build. Your practice data is yours — exportable to CSV any time.
Why only 100 lifetime seats?
Because I want the validation signal. If 100 adults pay $99, I know this product matters. If they don't, I'd rather find out now than after building for a year.
When does it launch?
Summer 2026. Waitlist seats get first dibs on the lifetime.
Buy once. Practice for a decade.
Waitlist seats go first on lifetime ($99, first 100, never reopens).
