Mass participation will generate an incredible database of images that, when analyzed together, could allow scientists to more accurately model the Sun. "We don't know the shape of the Sun?" you ask. Nope. Well, not exactly. Scientists have a pretty good idea, but it's not nearly as precise as it could be. Our hope is to change that—to measure the Sun's oblateness to an accuracy of a few parts in a million! This app uses your location to determine the time that totality will start and end there. This allows it to automatically take photos chock-full of data of the eclipse while you don't have to worry about the precise details! After totality, you can choose to upload the photos that were taken, along with a few other details about your location at the time of the eclipse and what settings your phone's camera was using, to our data servers for scientific analysis. What is citizen science? Citizen science is a collaborative style of research involving volunteers from the general public. The contributions of these “citizen scientists” help researchers collect and analyze large datasets. Citizenship is NOT a requirement. How will this project contribute to heliophysics research? We are aiming to create the first large-scale database of Baily's Bead images, which will allow the Sun’s shape to be precisely determined to within a few parts per million. Just as the precise shape of the Earth’s ocean surface allows us to determine flows inside the Earth, the SunSketcher database will allow us to study flows in the solar interior. In addition, knowing the precise shape of the Sun will allow physicists to test against and possibly disprove different theories of gravity, including General Relativity! Are there requirements or qualifications needed to participate? Can I participate if I’m not a scientist? You do not need to be a scientist to participate. Our aim is to involve as large and diverse a group of SunSketchers as possible. Why should I participate in SunSketcher? The unique aspect of SunSketcher is that everyone with a phone can make a valuable contribution to a state-of-the-art science project. No special equipment is required, just a smartphone. And, if you register as a SunSketcher on our site, we will add your name to the list of contributors. You might even get mentioned as a Guinness World Record Holder! Where do I have to be on the eclipse day? Anywhere inside the path of totality. Will I be able to watch the eclipse at the same time that I'm using SunSketcher? YES!! In fact, we encourage you to view the eclipse on your own (with appropriate safety precautions at appropriate times) while SunSketcher is running on your phone. The scientific quality of the images obtained will be best if the phone is left untouched throughout the few minutes between the start and end of totality. The app will be finished with the nitty-gritty science stuff just a minute or two after totality ends, at which point you can pick up and begin using your phone again. ## SunSketcher Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/e5/fc/6f/e5fc6f13-b245-4f83-06b6-d350b3999936/44aa7c5d-b6a4-42c0-a829-874d1cff12cc_Main_Screen.png/1242x2208.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/c0/0d/6e/c00d6e49-c0eb-d2df-7c31-cc6b8bebda04/f1c8079b-4c9c-4b1b-8226-6b2357f65ec5_Terms_and_conditions.png/1242x2208.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/16/94/86/1694864b-1e71-9c2a-c35f-f170d8b577fa/7c5885df-2f18-4574-b84c-b87947a7244c_Location_Verification_Screen.png/1242x2208.png) - [Screenshot 4](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/51/ef/16/51ef16e1-559f-9bbd-9c9a-9a2ebbe91257/8178df17-12a4-47b3-843a-fb331397ee6b_Countdown_Screen_1.png/1242x2208.png) - [Screenshot 5](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/27/d5/04/27d50442-e125-3abf-7348-d6001adb1ab8/1696eeec-0b6a-4f40-bc33-8cb5414ad6dd_Countdown_Screen_2.png/1242x2208.png) - [Screenshot 6](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/fb/78/cd/fb78cd5d-4e0d-d66b-5ca5-0c094a218aec/41928b38-7efd-49f9-9c4c-1fb81e314513_Tutorial_Screnn_5.png/1242x2208.png) - [Screenshot 7](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/c2/29/b1/c229b133-3adf-5e6c-1bb1-4143209a63bb/b49b5caf-4a97-4250-81a7-2e092a536aa7_Learn_More_Screen_5.png/1242x2208.png) - [Screenshot 8](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/4d/ae/2d/4dae2d78-f79a-dfe1-215e-5ee03ab76259/d1261a1d-1a98-49c4-a352-a24ca05f257f_Share_Photos_Screen.png/1242x2208.png) - [Screenshot 9](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/16/06/f4/1606f452-edc4-38f2-db1d-de5dbe15386c/91140833-110e-4f95-8001-182576204aad_simulator_screenshot_62E67662-4E9E-4DA6-9A77-AB8E173A71C9.png/1242x2208.png) - [Screenshot 10](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/81/1a/ee/811aeebc-fcbc-951a-8379-2459a8d3c369/8d267f52-aa8c-46ef-9c0e-b3f5f97bfe1f_simulator_screenshot_E6C46580-7979-4B52-869D-3CC77A2071A1.png/1242x2208.png) ## SunSketcher Rating Breakdown in United States - 5 stars: 5 (22%) - 4 stars: 4 (17%) - 3 stars: 2 (9%) - 2 stars: 1 (4%) - 1 stars: 11 (48%) ## SunSketcher Reviews in United States ### *---- "Horrible" I was in Metropolis, IL for the eclipse and followed the directions as indicated on the site. My pictures all turned out black! I would have much rather had my phone to take pictures of the shadows, colors, sky, people etc… instead I have nothing. -- Sharon.Graham, 2024-04-14 ### *---- "Didn’t work" Idk if it collected the data or not, but I found no pictures nor was I even able to tell whether the phone was pointed correctly or not. -- Jay1928474, 2024-04-10 ### ***-- "Oops I guess I’m not smart enough to follow instructions" I think I should have had the camera faced like I was taking a selfie. I interpreted the directions as the other way. Missed giving my data from out at sea from Mazatlan this total eclipse because of it. SO if I ever get to see another one that is what I will do! Amazing solar flares visible at totality in the 3:00 position moving to the 4:00 position during totality -- CapnRex❤️, 2024-04-08 ### *---- "Incomplete app" I did my best to cooperate but the app was not helpful, i was in the 99.8% of the eclipse, i saw the solar flares but the app recorded ZERO -- PiaPetro, 2024-04-08 ### *---- "Didn’t work..at all!!" Followed direction. Didn’t pick up anything at all!! Disappointed to say the least! -- Swtrigal, 2024-04-08 ### *---- "Didn’t work" Didn’t get a countdown in the app and it said to set the phone down to take photos. Waited the full 10 minutes and images never showed up. Really disappointed.. was excited to capture this rare moment. -- A Camille, 2024-04-08 ### ****- "Simple instructions for competent iPhone users" I’ve read 2 previous reviews that indicated the reviewers couldn’t read the instructions in the app. It’s a simple fix for anyone to make on their own. If you’re using an iPhone, just go into your Settings, then select display & brightness. Scroll down to the text size tab & slide the bar to the left to make the text smaller. Problem solved. You can thank me after the eclipse. -- Max Frustration, 2024-03-24 ### *---- "Camera damage" As far as I know pointing your phone camera at an eclipse is going to cause permanent damage to it. If I’m wrong and someone wants to correct me then please go ahead. -- ,:):)?46.2(:;'u, 2024-03-23 ### **--- "Instructions are not completely viewable" The instructions cut off at the bottom of the slide. I was unable to determine a way to continue with them. Will be deleting the app. Unfortunately. -- Howkim, 2024-03-23 ### ***** "Complete instructions on website" FYI if anyone needs to see the full tutorial for the app it is available on the website. Looking forward to using this app and doing some citizen science with my students in the zone of totality. -- livingit2020, 2024-03-23 [View all SunSketcher reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## SunSketcher Discovered Keywords - sunsketcher ## Apps Similar to SunSketcher - [Slow Shutter Cam](https://apptail.io/app/slow-shutter-cam-bx/united-states) - [The Photographer's Ephemeris](https://apptail.io/app/the-photographers-ephemeris-iA/united-states) - [PhotoPills](https://apptail.io/app/photopills-Sgd/united-states) - [TinType by Hipstamatic](https://apptail.io/app/tintype-by-hipstamatic-RJf/united-states) - [Nocturne by Unistellar](https://apptail.io/app/nocturne-by-unistellar-egJ/united-states) - [NightCap Camera: Long Exposure](https://apptail.io/app/nightcap-camera-long-exposure-VsL/united-states) - [Solar Eclipse Timer](https://apptail.io/app/solar-eclipse-timer-LOMf/united-states) - [Solar Snap](https://apptail.io/app/solar-snap-Adij/united-states) - [Photon Camera](https://apptail.io/app/photon-camera-TJan/united-states) - [Seestar](https://apptail.io/app/seestar-EWfn/united-states) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
