Pricing FAQ
Is there a free trial?
Not currently. LivaFast is a one-time purchase — no subscription, no in-app purchases. If you're unsatisfied, Apple's App Store refund policy applies within 14 days.
Does Family Sharing work?
Yes. One purchase covers up to 6 family members through Apple Family Sharing. Each person gets their own private data store.
Will the price increase?
We may adjust pricing for new customers as we add features, but your purchase locks in access to everything — current and future. No upsells, no "premium" tiers.
Why not a subscription?
Subscriptions create misaligned incentives. A subscription app needs you to stay sick so you keep paying. We want you to get better — and keep the app as a reference long after your liver numbers normalise.
