DWARFLAB smart telescope, empowered by advanced technology, opens up a world of diverse perspectives for users, capturing the wonders of life. No guidance or experience needed, it's ready to use out of the box. Wireless Connection Use the App to connect wirelessly with DWARFLAB smart telescope, enabling not only precise control but also making the shooting process more flexible and efficient. Astrophotography The App features an in-built star atlas, allowing you to simply tap on the celestial you desire to proceed with automatic star tracking and enjoy real-time image stacking. You can also adjust the astro curves and personalize the color grading to create your own 4K astronomical images. In-App Post Processing Capture, select, stack, and enhance — all in one seamless workflow for astrophotography. Supports both onboard stacking and cloud-based processing, with multi-format export options to make every astro image crisp and brilliant. Motion Tracking You can freely select the target to track on the shooting interface, enjoying the flexibility of manual selection; or you can use the telescope's automatic recognition function, which intelligently identifies tracks, and starts recordings, easily capturing dynamic scenes such as bird predation, flights, and sports close-ups. Gigapixel Panorama Simply set the shooting range and tap to start — with one-click stitching, you can create extremely detailed and vast panoramic images, supporting deep zoom and experiencing an unprecedented level of detail richness. Time-Lapse Photography Capture the flow and changes of time, recording the hustle and bustle of traffic, the blooming and wilting of flowers. Combined with astronomical tracking functions, it can also record the trajectory of the sun, solar/lunar eclipses, and the star trails.

SunSketcher is a citizen science initiative anyone can use to photograph the April 8th, 2024 Great North American Eclipse. 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.

Verdict
The clearest difference is rating: DWARFLAB at 3.5 against SunSketcher's 2.6. DWARFLAB also leads on ratings volume (141 vs 23) and device support (3 vs 1). SunSketcher's advantage is update cadence (fortnightly vs every 5 weeks). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
DWARFLAB holds the better App Store score, 3.5 against 2.6. That said, the two scores are not equally well evidenced: DWARFLAB has 141 ratings behind it against 23, so its average is the more settled of the two. Written reviews point the same way: 36% of DWARFLAB's written reviews are positive against 33% of SunSketcher's.
DWARFLAB ships an update every 5 weeks, SunSketcher fortnightly. The most recent releases landed on October 16, 2026 and October 3, 2026 respectively.
