## What is Rosyn?

Meet Rosyn, a calm and private cannabis companion made for adult cannabis users who want to be more intentional about their use.

Rosyn is not here to convince you to start using cannabis, use more, or quit. It is built for adults who already use cannabis and want a better way to understand their habits, learn from their experiences, and make more informed choices.

Think of Rosyn as a budtender in your pocket, a personal cannabis journal, and a pattern finder all in one.

Ask Rosyn about strains, terpenes, potency, methods, timing, and common effect patterns. Learn what myrcene, limonene, pinene, or caryophyllene may mean, and get plain-language context before your next session.

Because cannabis is personal, Rosyn helps you go beyond generic strain descriptions. A strain that feels relaxing for one person may feel heavy, foggy, or distracting for someone else. With Rosyn, you can log what you used, how you used it, when you used it, and how it actually felt.

Over time, your logs become a clearer picture of what works for you. You can track flower, vapes, edibles, tinctures, concentrates, topicals, and custom methods, along with potency, amount, mood, timing, effects, notes, and ratings.

Rosyn also supports voice logging, so you can quickly describe a session without filling out every detail by hand. Say what happened, and Rosyn helps organize the important parts.

As your history grows, Rosyn helps you notice patterns across strains, terpenes, methods, doses, moods, time of day, and effects. You may discover which products fit evenings better, which methods last longer than expected, or which routines are becoming more automatic than intentional.

Rosyn can also help you understand tolerance changes over time. Tolerance can shift slowly, and it is easy to miss until cannabis no longer feels the way it used to. Rosyn compares your recent sessions with your own history so you can see when frequency, amount, or effectiveness may be changing.

When it looks like you may need space, Rosyn can help you consider a pause, reset, or slower pace. No shame. No scare tactics. No pressure to quit. Just a gentle way to reflect and decide what feels right for you.

Rosyn is made for adult cannabis users who want cannabis to stay helpful, intentional, and personal. Whether you use cannabis to unwind, get creative, sleep, manage discomfort, or simply be more present, Rosyn gives you a private place to track, reflect, and learn.

Your cannabis history is personal, and Rosyn is designed with that in mind. There are no social feeds, public profiles, or judgmental streaks. Your logs are for you. If you choose, you can export your history for your own records or to share with someone you trust.

Rosyn does not replace medical advice, professional care, or your own judgment. It simply helps you understand what you are using, how it feels, and what patterns are forming over time.

Ask. Log. Learn. Adjust.

Use cannabis with more intention.

### 5/5 — One of my favorite apps!

*2026-01-26*

I downloaded Lunar Guide feeling a bit skeptical—kind of like when you try a fitness tracking app and think, “Okay, how much can this really help?” But I was genuinely surprised by how awesome this app is. It has a ton of features while still being super easy to navigate. It’s also incredibly informative; I’ve learned so much in just a few weeks that I never knew before. I’m more clear headed, more present, and enjoy using cannabis more than I did before. I feel like I’m getting the most out of it now. One of my favorite apps!

### 5/5 — Keeps me In control

*2026-01-21*

Lunar Guide is wonderful and has helped me stay in control of my cannabis usage.  I’ve been able to rest myself and enjoy my life again.

### 5/5 — Thoughtful, calming, and genuinely helpful

*2026-01-18*

Luna Guide feels like it was made by someone who actually understands intentional cannabis use. There’s no guilt, no pressure to quit, and no overwhelming charts or data—just simple, reflective tools that help you notice patterns and stay aware of your relationship with cannabis over time.

I especially love the moon-cycle approach to tolerance. It’s intuitive, visual, and surprisingly grounding. Logging sessions is quick and easy, and the focus on how you actually feel—not just what or how much you used—makes this feel more like a mindfulness practice than a tracker.

The app doesn’t tell you what to do or shame you into changes. It simply reflects what’s happening and gently supports better awareness and balance. The privacy-first design is also a huge plus.

If you already use cannabis and want to be more intentional, present, and informed about your habits—without judgment—this app is absolutely worth it. Calm, respectful, and refreshingly human.

### 5/5 — New to Cannabis

*2026-01-17*

This has been extremely helpful with keeping track of my edible usage. It also provides a mindful cannabis experience with guidance on possible tolerance breaks and great reminders to log my edibles along with helping me keep track of how I’m feeling each time.

### 5/5 — Helped me improve my smoking routine

*2025-08-07*

Surprisingly this app really helped me tamper my smoking. Monitoring when and how much I smoked was not something I did before. But once I got into the rhythm of monitoring my habit I was able to figure out how to smoke less while still keeping the benefits. This app also is helpful in that it ties you into a celestial rhythm that makes sense. You dont have to figure out the tempo of your habit because its already built in and tied to the moon.

### 5/5 — Beautiful app

*2025-08-06*

There is a lot to it. A rich app. I like that it thoughtfully takes you through sessions, medicinal especially.
