Remember what worked, and what didn't. Cannoisseur is a private cannabis journal for patients and enthusiasts. Log every flower, vape, concentrate, edible, topical and tincture you try, and build a personal record of how each one made you feel. Next time you shop, you'll know what to look for. LOG EVERYTHING THAT MATTERS - Product name, type and dominance (indica, sativa or hybrid) - A 1–5 leaf rating and your own notes - Up to four photos of the product or label - Voice notes, transcribed on your device so you can read and search them later - What it helped with, from pain and sleep to focus and stress - Side effects such as dry mouth, anxiety or couch-lock - Where you bought it, with a map - Cannabinoid and terpene percentages from the lab label, including THCA, CBD, CBN, Total THC, myrcene, limonene and more Missing a terpene, symptom or side effect? Add your own. FIND ANY ENTRY IN SECONDS Search by strain, dispensary, symptom, or anything you said in a voice note. CANNOISSEUR PRO Turn your journal into personal research: - Shopping guide: pick a symptom and see the cannabinoids, terpenes, strains and dominance that worked best for you, with typical percentages to look for on the label. - Side-effect warnings: while you log, get a heads-up when a product or its compounds have been linked to side effects in your past entries. - What works for you: find the compounds that lift your ratings above your usual, and the strains and compounds behind your side effects. - Share a report: export a PDF summary of your journal to bring to your doctor or budtender. - Trends and favorites: your monthly rating trend and your best-rated dispensaries. Insights compare each result to your own average, and small samples count for less, so one great night can't top the list. PRIVATE BY DESIGN Your journal syncs through your own iCloud account. There are no ads and no sign-up, and voice transcription happens on your device. MADE FOR EVERY SCREEN Built for iPhone, iPad and iPhone Duo, with VoiceOver and Dynamic Type support throughout. BUILT BY ONE PERSON Cannoisseur is made by an independent developer. Pro subscriptions keep the app ad-free and fund new features for patients and enthusiasts.
Be I/O

Be I/O makes sense of air quality in terms that apply to you. Rather than broad categories like "moderate" or "unhealthy," Be I/O estimates how much PM2.5 you'd actually take in, right now, doing what you're planning to do. Choose an activity — a 30-minute walk, or a 75-minute hard run — and see whether to Be Inside or Outside for it, and how much of your estimated daily intake it would account for. Be I/O works out your ventilation rate from optional health details: age and weight, or your resting and maximum heart rate, or — for the fitness nerds — the litres per minute you breathe in each heart rate zone, straight from a metabolic test. Connect to your own PurpleAir or AirGradient sensors over your local network for near-real-time readings, free and without an account. No sensor of your own? Subscribe to use the public monitor nearest you. A subscription adds: * Air quality from the sensor nearest you, wherever you are * What each run, ride and walk of the last 30 days cost you, from Apple Health * A week of sensor history (for public sensors) * The Apple Watch app: current air quality, your estimated breathing rate and PM2.5 intake, each optionally shown against a baseline you choose * A PM2.5 gauge Apple Watch complication Note: Be I/O estimates are fitted to adults; the app says so when it knows you're younger.

Verdict
The clearest difference is in-app purchases: Cannoisseur at none against Be I/O's 1. Be I/O's advantage is update cadence (every 3 days vs monthly) and device support (3 vs 1). On price and ads there is nothing between them.
