Bugs? prevent editing and displaying updated entries on UI ### 1/5 — Needs work- has potential *2022-12-21* The ability to write my own notes should not be what I publish for everyone to see. The app for foes not feel private. I’m also trying to close the account info and there’s nowhere to press to do so. ### 5/5 — Essential app! *2022-08-24* 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. ### 5/5 — Keeps track for me! *2022-06-23* This app has been a great help, highly recommend! ### 1/5 — Broken *2022-02-05* Every time I click a strain while attempting a new session, the screen goes white and I have to back out eventually as nothing happens. ### 2/5 — Non-comprehensive app with one major flaw *2021-12-28* 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). ### 5/5 — Very detailed *2021-11-18* When I first got my medical card the dispensary gave me a sheet to track what strains I use I had to write down what I had issues with What the effects were and what I was treating. I’m so glad somebody decided to put this in the app and I can see what’s worked for other people too. such an amazing app ### 5/5 — *this* is the tool I need!!! *2021-10-16* This app is exactly what I have been searching for - I have tried them all. Love that it’s customizable and so easy to use. Nothing confuses me - some of those apps were like a puzzle. Tetragram is a great tool, cool name, painless use experience. Highly recommend and will mention to my dispensaries. Well done! ### 4/5 — This App is almost perfect *2021-06-13* 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. ## Frequently asked questions about Tetragram ### What is Tetragram?
