eBird vs areoHDR

eBird Mobile makes it easy to record the birds you see in the field, and seamlessly link these observations with eBird--a global online database of bird records used by hundreds of thousands of birders around the world. This free resource makes it easy to keep track of what you see, while making your data openly available for scientific research, education, and conservation. eBird Mobile is the only app that passes information directly from the iOS device to your eBird account on the web. Features - Enter bird observations from any location around the world. - Full global taxonomy based on The Clements Checklist of Birds of the World. - Common names available in local languages (e.g., Portuguese names in Brazil or in Portugal). - Checklists customized for your location and time of year, showing most likely species based on eBird data. - Rare species flagged during data entry and on the checklist. - "Record as you go" functionality for incremental list keeping and counting while birding. - GPS enabled location plotting to ensure accuracy. - Map tools that enable selecting from hundreds of thousands of eBird "Hotspots." - Full offline functionality, enabling use in places with limited or no Internet connection. - Trip and Day list functionality that makes it easy to keep track of your species list on a particular outing. - Support for iPhone, iPad, and iPod Touch. - Entire app translated to German, Mandarin, French, Spanish, Portuguese (Brazil), Turkish, and Dutch.

With HDR, the images glow brightly in high contrast on the screen, not visible here in the screenshots as it can only be experienced on the device. The areoHDR app shows images taken only a few hours ago on planet Mars by NASA Perseverance Rover, which landed on 18 February 2021 and is currently driving in and around Jezero Crater. Since version 1.5.0 all color images taken by Viking Lander 1 & 2 are also available. Viking Lander 1 touched down on 20 July 1976 as first successful landing on another planet. This is currently the only app showing real Mars images in high dynamic range (HDR) and color calibrated for human vision to bring the experience, human explorers on Mars would have themselves, to iPhone and iPad. To navigate through the sols (days on Mars since landing) and images of each sol, either tap on the two up/down buttons on the right side or swipe horizontally or vertically or rotate the wheel with the sol numbers. Double tap or pinch with two fingers to zoom in and out. The images are taken by the 20 Megapixel Navcam pair inside the rover's "head" 2m above the surface, the two 20MP front and rear Hazcam pairs near the ground, Watson Camera on the robotic arm and Cachecam in the underside sample storage bay. A Mars calendar ist now available by long press on the arrow-down button where the day on Mars (sol) can be selected via the position in the astronomical solar year or the date on Earth. HDR works on all iPhone & iPad Pro models released since late 2018 and all Macbook Pro since M1. Other devices will also show the images, but not in full HDR. No AI processing is applied to the images and no artificial color adjustment. This is the real view on Mars! The color processing uses a preset white-balance set to sunny daylight on Earth, to visualize the experience a human explorer would have on the Mars surface. That is the same configuration available on any commercial digitial camera when setting it to manual daylight white-balance. The raw image data used to produce the color processed images is publicly provided by NASA / JPL-Caltech. The color processed images shown by the App are separate derived data products and created by the app author's backend system. The free version allows access to the latest 200 sols (days on Mars since landing). By subscribing within the app, you can access all more than 1500 Mars-days since landing sol 0.
