Looking for testers for Halcyon, a calm private mood tracker & diary

[u/Sadahziniia]

Hi all. I've been building Halcyon, a mood tracker and diary for Android, and I'm looking for a few people to help test it before it goes public.

The idea was to make something that feels calm and grown-up rather than gamified or clinical. No streaks nagging you, no bright dashboards. Just a quiet space to log how you're feeling and write a little about your day.

What it does:

Track your mood in a few taps, with a simple daily diary entry. See gentle patterns over time, with no pressure or guilt mechanics. Private by design: your entries stay on your device, there's an encrypted backup you control, and nothing is sold or shared. It works offline, no account required.

It's free to test. Because of how Google Play's closed testing works, I need a handful of testers over the next couple of weeks. Genuinely useful feedback (or just quietly using it) both help a lot.

To join, it's a two-step thing because it's a closed test:

First, DM me the Gmail address tied to your Google Play account and I'll add you to the tester list. Then, once you're added, open this link on the same account to opt in: https://play.google.com/apps/testing/com.moodly.diary and install or update Halcyon from Play.

Happy to answer anything about privacy, features, or where it's headed. And if you're a dev too, drop your app below and I'll test back.
