# Hubble vs Space Telescope App

The clearest difference is review sentiment: Space Telescope App at 40% against Hubble's 0%. Space Telescope App also leads on update cadence (every 10 days vs every 6 weeks) and ratings volume (30 vs 7). Hubble's advantage is in-app purchases (none vs 4) and rating (4.3 vs 4.0). On price, ads 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. Hubble asks for nothing beyond the download.

Hubble holds the better App Store score, 4.3 against 4.0. Both are backed by a comparable volume of ratings — 7 and 30 respectively. Written reviews complicate that: 0% of Hubble'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.

Hubble ships an update every 6 weeks, Space Telescope App every 10 days. The most recent releases landed on September 11, 2026 and September 25, 2026 respectively.
