App doesn’t work

The app didn’t even work, don’t waste your time like I did

My Favorite Mental Health App

I’ve never felt safer on an app. It’s so calming and the colors make me happy! It’s nice to finally have a mental health app that genuinely helps and I don’t have to pay for!!!! 💜💜💜

Confused

The app doesn’t even work, it won’t log my moods and the mood chat doesn’t even respond

My 24/7 Therapist

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.

An app that gets me

Love this app! The design is soothing, the reflections feel human, and it actually helps me pause and breathe. It’s like a daily reset button.
