DWARFLAB App vs Heavens-Above

DWARFLAB App is a free mobile application for wirelessly connecting to and controlling DWARFLAB smart telescopes. It runs on Android, iPhone, and iPad, with offline access, an AR sky view, and learning content. The download page lists DWARF mini, DWARF 3, and DWARF II as supported telescopes. Astrophotography tools include a star atlas, automatic star tracking, real-time and onboard image stacking, astro-curve adjustments, color grading, cloud processing, and multi-format export. You can select a moving target manually or use telescope recognition to track and record it. One-click gigapixel panorama stitching and time-lapse photography support tracking of the Sun, Moon, and stars. An account is optional for telescope control. Community functions may support publishing, comments, interaction, and sharing. Logs can be uploaded for troubleshooting; uploaded logs are retained up to 14 days.

Heavens-Above provides satellite predictions and sky information through Android, iOS and web access. The website lists 10-day predictions for selected satellites, daily predictions for brighter satellites and Starlink passes from a launch. It also offers a live sky view, interactive sky chart, dynamic 3D Starlink orbit display and interactive 3D ISS visualization. Charts and information cover the Sun, Moon, planets, comets, asteroids and constellations. The Android app includes predictions for the ISS, visible satellites and radio satellites, plus orbit and ground-track views, night mode and an orientation-based tracker. Selected passes can be added to a device calendar. Predictions run locally, with a data connection needed every few days. The free plan costs nothing; Heavens-Above Pro costs $4.99, paid once and removes Android adverts. Predictions become less accurate farther from the current date.
