Verdict

The call

The clearest difference is review sentiment: Exoplanet at 91% against Reentry AR's 33%. Exoplanet also leads on ratings volume (956 vs 1). Reentry AR's advantage is in-app purchases (none vs 7) and update cadence (every 3 days vs every 2 weeks). On price, ads, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Reentry AR holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Exoplanet has 956 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 91% of Exoplanet's written reviews are positive against 33% of Reentry AR's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Exoplanet ships an update every 2 weeks, Reentry AR every 3 days. The most recent releases landed on September 21, 2026 and September 2, 2026 respectively.
