After the trial, you can pay $9/month or $99/year (8.3% off) for sleep or relief settings, or $19/month or $199/year (12.7% off) for the full library.
Can I use Harmoniq without a membership after the trial?
Yes, you can use Harmoniq with a limited set of signals without a membership, though the subscription is highly recommended to get the full benefits including all mood signals, new signals added over time, and app updates.
