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. Download Rosyn and get to know your cannabis routine better. https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Stash Journal — Cannabis Tracker Stash Journal is the most thoughtful way to track your cannabis experience. Whether you're exploring new strains, trying different products, or fine-tuning what works best for you, Stash Journal gives you a private, beautifully designed space to log, rate, and learn from every session. Your Complete Cannabis Journal Track both strains and products in one place. Log flower, pre-rolls, vapes, edibles, tinctures, concentrates, and more — each with their own detailed profile. Record the type, form, brand, potency, lineage, effects, flavors, and terpenes for everything in your stash. Add personal notes and star ratings to capture exactly how each experience felt. Stash AI Chat — Your Personal Cannabis Advisor Meet the AI that actually knows your stash. Stash AI Chat is a built-in conversational assistant that reads your entire journal — your strains, products, ratings, effects, and notes — and gives you personalized recommendations in real time. Just ask. "What should I try for a creative afternoon?" "Which of my indicas is best for winding down?" "I haven't tried anything new in a while — what fits my taste?" Stash AI searches your logged sessions, surfaces your highest-rated matches, and suggests new strains worth exploring — all based on your own data, not generic recommendations from the internet. Follow up naturally. Refine your question, dig deeper into a suggestion, or explore a different mood. Every answer is drawn from your personal journal — nobody else's. AI Auto-Fill — Just Type the Name Stop spending time on data entry. Stash Journal's built-in AI can automatically fill in a strain's description, lineage, effects, flavors, and terpenes the moment you type its name. Review the suggestions, make any tweaks, and save in seconds. The more you log, the better your personal records become. Label Scanner Point your camera at any product label and let the AI do the reading. Stash Journal's label scanner detects the product name, brand, THC percentage, and type automatically — so adding a new product is as fast as taking a photo. No more typing out every detail by hand. Detailed Strain & Product Profiles Every entry gets its own rich profile page. See your star rating, effects chips, flavor notes, lineage, terpenes, potency, personal notes, and usage history all in one beautifully organized view. Build a reference library of everything you've tried, exactly the way you remember it. Discover What Works for You Stash Journal learns your palate as you log. The dedicated Insights tab unlocks after your first five entries — surfacing your most-loved effects and flavors, average ratings by strain type, standout terpenes, and highlights from your journal. The more you track, the sharper the picture gets, so every session helps you make a more confident choice next time. Search & Filter Instantly Find any strain or product instantly with built-in search. Filter your journal by type, form, or effect to quickly surface what you're looking for — no scrolling through a long list. Private & Secure Sign in with Apple or Google. Your journal stays private, synced securely to your account, and accessible only to you. Clean, Natural Design Stash Journal was designed with an earthy, premium aesthetic that feels right at home on your iPhone — warm creams, forest greens, and a focused layout that keeps your data front and center. Stash Journal requires users to be 21 years of age or older. Available in the United States only. Built on Bainbridge Island.
