Free · In‑App Purchases
Yellowstone Wolves: The Years provides up to 7 years of annual snapshot data of Wolves, Packs & Territories. It is a free app that contains the 2019 data. In-App Purchases (IAPs) let you get the data for 2020 thru 2025. With this additional data, you get functions not available with 2019, such as interfacing with Yellowstone SPOTR to relate Packs & Pullouts.
2025 is very significant because it celebrates the 30th year since the Wolves were reintroduced into Yellowstone NP in 1995. This app provides you the latest 7 years data.
You can choose among the following functions for the 2019 data:
- Map - locations of the Packs, which you can select on the map
- Details - main information for selected Pack & Wolves is shown first
Additional specifics can be shown by touching one of the icons at the top right of the screen:
• Wolf Statistics
• Search Results Totals, including the Search Criteria that produced the selection
• Pack Summary & Legend
Touch the Details icon at the bottom of the screen to see information for all packs
- Search - criteria to select a specific set of Packs & Wolves in the Details screen
For example, you could search for all collared wolves or all wolves with a specific coat color
- Graph - choose from various collected statistics
- About - explanations, descriptions, legends & contact information

You can purchase additional years by using the Catalog and then use the Year Choice function to select which year to view. All of the functions listed above are available for these years. You can also interface with Yellowstone SPOTR to see Pullouts where the Pack might be seen.
In addition, Yellowstone SPOTR provides a function in the details for a Pullout. You can choose to show which Packs might be seen from that Pullout.
After installation & purchase of IAP Products, Wi-Fi access is not needed to use the app.
