Therma vs Daylio
Daylio is the fastest mood tracker on the market. Therma takes 10 more seconds and tells you what your mood actually means. Here is the honest comparison.
By Omar Rantisi, Founder of Therma
The 30-second verdict
Choose Daylio if you want pure quantitative tracking with zero friction and you'll do your own pattern analysis. Choose Therma if you want the same fast logging plus an AI that finds the patterns for you, integrates with Oura and Apple Health, and helps you understand why your mood shifts.

When to choose which
Choose Therma
You want to understand your patterns, not just record them. You already track sleep, HRV, or workouts and want the missing emotional layer. You like the idea of an AI that asks one precise question instead of giving you a blank page.
Choose Daylio
You want the absolute fastest mood logger and you'll do your own pattern analysis. You're wary of AI in personal health data. You're on Android and want something today.
Common questions
Is Therma a Daylio clone with AI bolted on?
No. The check-in is similar in spirit (fast, low friction), but the rest of the product is different. Daylio is a personal database. Therma is a personal feedback loop. Daylio gives you data; Therma gives you weekly insight reveals that tell you what the data means.
Can I export my Daylio data into Therma?
Not directly yet. CSV import is on the roadmap for Therma's public launch. For now, you can start fresh on Therma and your Daylio history remains untouched on your existing account.
Which one has better privacy?
Both are reasonable. Daylio uses cloud backup with optional encryption. Therma is end-to-end encrypted by default and HIPAA-aligned. If you want zero-knowledge encryption out of the box, Therma is stronger. If you want a battle-tested mature product, Daylio has been around longer.
Why is Therma slower per check-in?
Because the value is in what happens after. Daylio's 5-second check-in is great if you're only logging. Therma's 60-second check-in includes one AI question that adapts to your recent patterns. The extra time is what produces the weekly insight reveal.
