The GLOBE Observer app enables you to make observations of your environment. GLOBE Observer is the app of the Global Learning and Observations to Benefit the Environment (GLOBE) Program. The GLOBE Program is an international science and education program that provides students and people of all ages worldwide with the opportunity to participate in data collection and the scientific process, and contribute meaningfully to our understanding of the Earth system and global environment. By using the GLOBE Observer app, you contribute scientific data to your community, students and scientists worldwide, including researchers at NASA, NOAA, and other science research institutions. GLOBE Observer allows all users to contribute observations of clouds, mosquito habitats, land cover, and trees. Trained and certified users can also use the app to submit additional environmental measurements from all GLOBE protocols. GLOBE Clouds allows observers to make regular observations of Earth’s cloud cover and compare them to satellite observations. With GLOBE Mosquito Habitat Mapper, users locate mosquito habitats, observe and identify mosquito larvae, and reduce the potential threat of mosquito borne disease. GLOBE Land Cover is designed to allow users to document what is on the land (trees, grass, buildings, etc.). GLOBE Trees asks users to estimate a tree’s height by taking pictures of trees with their device and answering a few questions. Additional capabilities may be added.

** This app is currently available ONLY TO CADETS WHO ARE MEMBERS OF WINGS IN THE PACIFIC REGION (Alaska, Hawaii, California, Oregon, Washington and Nevada). It will be expanded to other regions as soon as possible. Please only download if you are a member of one of the above wings. Please DO NOT LEAVE A REVIEW if you are outside the Pacific Region. ** Dear Civil Air Patrol Cadet, A mobile application has been created to help you with what matters most to many cadets - earn your next promotion! This application, engineered by Nevada Wing CAP members for your iPhone or iPad, automatically connects to the internet to determine what requirements remain for your current achievement. It is designed to show you these requirements at a quick glance in a readable format. You may look back and see what you’ve already accomplished, and even look all the way forward to learn everything you will need to earn the coveted Spaatz award. Additionally, you can request to add other cadets as friends and compete with them for your promotions! We hope you will find this app helpful in speeding you along your way through the CAP cadet program. There is absolutely no charge to use this service and there never will be. You just need an iPhone or iPad capable of running iOS 16 or higher. The only other requirement is that you must have an active email account that matches your contact information in eServices. When you first open the app, you’ll be asked to log in one time with your CAP email address, month/year of birth and CAPID. You will then receive an e-mail to the address you entered. Follow the instructions in that e-mail. Upon logging in, you will be taken to your current achievement. Navigating the app should be self-explanatory. Click on the subjects for your achievement to see further details, or click on the achievement name itself to see other achievements, past or future. To see a friend’s progress or add a new friend, tap the plus icon next to your name. The database is updated nightly, so anything you accomplish will be reflected in the app the next day. Go forth and advance your education and training rapidly!

Verdict
The clearest difference is rating: CAP Cadet Promotions at 3.5 against GLOBE Observer's 3.1. GLOBE Observer's advantage is update cadence (every 2 months vs every 8 months) and ratings volume (91 vs 10). On price, review sentiment, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
CAP Cadet Promotions holds the better App Store score, 3.5 against 3.1. That said, the two scores are not equally well evidenced: GLOBE Observer has 91 ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 34% of GLOBE Observer's written reviews are positive against 27% of CAP Cadet Promotions's, so the app with the better star average is not the one people write more warmly about.
GLOBE Observer ships an update every 2 months, CAP Cadet Promotions every 8 months. Both last shipped on October 24, 2026.
