## Rockd Reviews in United States

### ****- "Love it but…"
I really enjoy using this app and appreciate how well it functions overall. As a geologist and amateur paleontologist, I find it incredibly useful. However, I’ve noticed that the taxa tab can take some time to load, which can be a bit challenging during my work. I’d love to see this area optimized in future updates to make the experience even better. Thank you for your hard work!
-- Fenrirfenn, 2024-11-27

### ***** "Absolutely phenomenal"
This resources is fantastic for amateur and professional geologists alike, with peer reviewed references and an easy to navigate interface.
-- L Almighty, 2024-11-03

### ***** "Amazing Geology App"
This app is great for someone interested in understanding the geology of an area. I am surprised at how good it is for a free app! Thank you whoever created this!
-- vtshep, 2024-09-04

### ***** "100/10"
Best app on the app store. It has everything anyone could want pertaining to geology. From beginners to experts, this is an absolute must for anyone who has an interest in rocks. (even has a fairly servicable Brunton compass)
-- lohreo, 2024-07-28

### **--- "Why can’t I search lat long!?"
It would be much better if I could search lat long when I’m in service. App is basically useless when I’m out of service in field situations.
-- Dilly Dewey Hadden, 2024-07-22

### ***-- "Feature suggestion"
Often the color coding for adjacent formations are so similar its very difficult to tell them apart and in some lighting conditions it’s. He’s consider adding a toggle layer to draw black lines on the contacts as shown on the map.
-- TheSilurianHypothesis, 2024-04-02

### ***** "Changed how I view earth!"
Everytime u visit a new place I'm always checking in on rockd. I can now better understand the geology and depositional environments. I use the app to record fossils that I've found.
-- MagicPITheAI, 2024-03-24

### ***-- "Just downloaded it. It’s rich with information but with a glitch"
The app is amazing. It’s responsive and seems precise. I’m not a geologist so I’m learning a new language. A rock is not just quartz but of a certain era, location and of a group all of which is deep information which is new to me and I very much enjoy the granular detail o puns intended. 

However I cannot sign up as the page jumps all over and will not let me go beyond entering my first name and then it jumps from the signup page to the login page. Probably a “feature” of a recent update. 
Please fix this as I think this app has great features but would like to join in. 
Would be more stars if I could login. Would also be much better if I could highlight a word or phrase to connect with the web to learn a definition or more information.
-- jyduchene, 2024-03-03

### ****- "Fun App with a Major Flaw"
I was told about this app by a friend that’s a geologist. He suggested using it when I’m out in the field for botanical surveys as a easy reference for local formations. Works fantastic when in cellular range, but the downloadable maps for when I’m out of a service area (which is almost every time) absolutely does not work. I’ve essentially had to screen shot the area and reference those to my GPS which is extremely hard. The All Trails app has that function and it works flawlessly. If the creators of this app got it working, I’d happily pay whatever subscription fee they would require to use it. All-in-all, it’s a fun app to use when you’re in cellular service, but do NOT depend on it for real-world applications.
-- Expediteplanb, 2023-12-03

### ***** "Amazing"
I love geology and paleontology!
-- Joe Dow, 2023-11-26
