Verdict
The clearest difference is rating: HiGrade at 4.6 against Cannabis Journal's 3.4. HiGrade also leads on review sentiment (85% vs 43%) and monetization model (free with in-app purchases vs subscription). Cannabis Journal's advantage is update cadence (every 5 days vs every 3 weeks). On price, ads, in-app purchases and device support there is nothing between them.
