Honest comparison

Therma vs Calm

You did not fail at Calm. You opened it in a hard hour, found a 12-minute breathing exercise, and closed the app. Calm is built for the night. Therma is built for the 11pm when sleep will not come and you cannot say why.

By Omar Rantisi, Founder of Therma

The 30-second verdict

Calm is a content library. You pick a sleep story, a meditation, a soundscape, and press play. Therma is a 60-second check-in. One adaptive question that knows what you said yesterday, then a weekly reveal that shows the pattern. The 10% difference: Calm gives you something to do at night. Therma shows you what the week actually looked like.

When to choose which

Choose Therma

You want a private place for the thing you cannot name. You have tried meditation apps and they worked when you remembered to open them, but the problem was never that you needed a session. You want a 60-second daily habit that tells you what the week actually looked like.

Choose Calm

You want a guided session to fall asleep to. You want celebrity-narrated content and the polished brand. You already have Calm Premium through an employer. Meditation as a daily practice is the thing you want.

Common questions

Is Therma a Calm alternative?

Therma is built for a different moment. Calm prescribes something to do. Therma reflects something to notice. One 60-second adaptive question. Forgiving streaks. A weekly reveal. If you opened Calm during a hard hour and closed it, you did not need a session. You needed a place to put the thing you could not name. That is what Therma is.

Why is Therma faster per session than Calm?

Because Therma is not a content library. Calm asks you to pick a session, then asks for 10-30 minutes. Therma asks one adaptive question that knows what you said yesterday. The whole interaction is one screen. The pattern reveal happens weekly, not in the moment.

Is Therma free like Calm?

Therma has a free tier. Paid plans are $9.99/mo or $59.99/yr. Founding Member is $39.99/yr, locked for life, first 10,000 subscribers only. Calm is $69.99/yr after a free trial. The Founding price holds even if Therma raises prices later.

Does Therma replace therapy?

No. Therma sits in the gap between silence and therapy. It does not diagnose, treat, or replace clinical care. It is a private companion for the 11pm when you cannot say why you cannot sleep. Feel it to free it.

Can I use both Calm and Therma?

Yes. They solve different problems and the daily time commitment is small (60-second check-in for Therma, 10-minute session for Calm). Calm at bedtime to fall asleep. Therma in the morning to see what the week is doing. They do not overlap.
