# NASA Visualization Explorer vs Space Telescope App

The clearest difference is rating: Space Telescope App at 4.0 against NASA Visualization Explorer's 3.3. Space Telescope App also leads on update cadence (every 10 days vs every 3 months). NASA Visualization Explorer's advantage is in-app purchases (none vs 4) and ads (none vs shown). On price, ratings volume and device support there is nothing between them.

Both are free to download. Space Telescope App sells 4 in-app purchases, starting at $4.99 per month. NASA Visualization Explorer asks for nothing beyond the download.

Space Telescope App holds the better App Store score, 4.0 against 3.3. Both are backed by a comparable volume of ratings — 86 and 30 respectively. Written reviews complicate that: 51% of NASA Visualization Explorer's written reviews are positive against 40% of Space Telescope App's, so the app with the better star average is not the one people write more warmly about.

NASA Visualization Explorer ships an update every 3 months, Space Telescope App every 10 days. The most recent releases landed on October 13, 2026 and October 7, 2026 respectively.
