A mood tracker and check-in space for when your head feels loud. GHP named Letheia Best Mental Health App of 2026.
Letheia: Mood Magic for Your Inner World
Letheia (Best Mental Health App 2026, GHP Mental Health Awards), is a mood tracker and self reflection tool for facilitating emotional awareness. Built with licensed counselors for the moments when your thoughts get too loud. Explore what you are feeling, and understand the layers to your emotions.
Letheia is not a therapist, it's just a safe place to say what you really feel with no judgment.
~ Let's check in ~
If you are low on energy just tap an emoji, or go deeper with the 3-level Emotion Wheel, from "Angry" to "Frustrated" to "Overwhelmed"
Actually understand the truth behind what you feel.
In return, receive "Truth Threads." Affirmations for you to keep close to heart. Favorite the ones that make a difference and come back to them whenever you need.
~ Take a minute to breathe ~
The Orb has 14 different breathing exercises synced to sound, vibration, and rhythm. Breathe in, breathe out, and feel yourself become more grounded.
~ Arcade ~
Sometimes you just want your brain to take a break, and not have to think. So we built an arcade.

~Talk it out ~
Sometimes a quick check-in isn't enough. Mood Chat is there for a full conversation. It listens, reflects what you are saying back to you, and sits with you during moments of big emotions. It will not give you advice (even what to eat for breakfast) or try to therapize.
~How Letheia keeps you safe~
Letheia runs on TruthSafe™, a patent-pending AI safety architecture built with licensed counselors, so you can be honest and safely listened to and interacted with.
Letheia is for
The late night overthinkers
The ones who feel things deeply
Anyone who says "I'm fine" when they're really not
Letheia has become my favorite app! I love how simple it is to choose my mood, jot down what I’m feeling, and reflect throughout the day. The AI features are surprisingly uplifting, whether it’s guiding me through quick breathwork, giving encouraging feedback, or helping me look back at my mood history, it always feels supportive rather than overwhelming.
My favorite mental health app

Letheia is amazing, it helps keep me grounded and understand my emotions better. The app is easy to use and has great breathing exercises. The games are also fun and useful to distract me when need it. I use it pretty much everyday and I don’t see myself stopping it’s been so useful and helpful
