Verdict

The call

The clearest difference is rating: TERC EarthLabs at 5.0 against Executive Command's 4.2. TERC EarthLabs also leads on iOS requirement (8.0 vs 12.0). Executive Command's advantage is review sentiment (79% vs 40%) and update cadence (every 6 months vs every 53 months). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

TERC EarthLabs holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: Executive Command has 83 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 40% of TERC EarthLabs's written reviews are positive against 79% of Executive Command's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

TERC EarthLabs ships an update every 53 months, Executive Command every 6 months. The most recent releases landed on October 4, 2026 and October 7, 2026 respectively.
