Verdict
The clearest difference is review sentiment: Planetary Compass at 100% against Astro Kit's 50%. Planetary Compass also leads on update cadence (every 6 days vs every 3 months) and iOS requirement (15.0 vs 17.6). Astro Kit's advantage is rating (4.6 vs 1.8) and ads (none vs shown). On price, in-app purchases and device support there is nothing between them.

Astro Kit holds the better App Store score, 4.6 against 1.8. That said, the two scores are not equally well evidenced: Astro Kit has 50 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 50% of Astro Kit's written reviews are positive against 100% of Planetary Compass's, so the app with the better star average is not the one people write more warmly about.
Astro Kit ships an update every 3 months, Planetary Compass every 6 days. The most recent releases landed on June 1, 2026 and September 15, 2026 respectively.
