This App is almost perfect

The only things you need to add are filters for your sessions, so you can track your strains by Indica, Sativa, and CBD Dom, not just small I, S, or H icons next to the strain name. As well as a Cannabinoid chart for easy access to the sights of your THC and CBD levels. This app is great and it is a weight off for me because I personally record every strain I buy medically. So having a resource like this is amazing, but with a few tweaks this app could be so much better. Maybe a mini chart that shows levels of microcannabinoids along with your main cannabinoid chart to check micro numbers.

Non-comprehensive app with one major flaw

I thought this app seemed fairly good until I found it is EXTREMELY easy to delete long, detailed entries with a single misclick and zero confirmation of deletion, just instantly gone. I spent a very long time entering all of the compounds and other information for a product and writing a detailed review/notes and when I went to click “edit” to add a photo of the product, I accidentally clicked slightly off to one side which hit “delete” and removed everything I had entered. What an incredibly frustrating feature and beyond poor design.

I also don’t believe there is any way to sort your data (at least not as far as I could ascertain) so if you’re wanting to sort by products/strains you most liked, symptoms, type of product or method of use, etc. I don’t believe there is any way to do so. Overall a very frustrating experience to have my work lost in an instant due to poor layout/app design. I removed the app as soon as I experienced this fatal flaw, I am not willing to enter such a significant amount of information when it can be so easily lost from one small misclick immediately next to an important feature I would be using often (Edit).

Essential app!

Incredible platform to keep a journal entry of each different strain I’ve used and exactly how it made me feel. I can choose to share the review publicly to the feed or I can keep for myself. The feed shows others personal journal entries which has been so helpful when looking for something new.
