# microTERA vs SpaceFields

The clearest difference is price: microTERA at $1.99 against SpaceFields's $10.99. microTERA also leads on rating (4.9 vs 4.7) and iOS requirement (11.0 vs 13.4). SpaceFields's advantage is chart position (#116 vs unranked) and update cadence (every 2 months vs every 4 months). On ads, in-app purchases and monetization model there is nothing between them.

microTERA costs $1.99 and SpaceFields $10.99 up front. Neither carries in-app purchases, so what you see is what you pay.

microTERA holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: SpaceFields has 47 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 81% of microTERA's written reviews are positive against 90% of SpaceFields's, so the app with the better star average is not the one people write more warmly about.

microTERA ships an update every 4 months, SpaceFields every 2 months. The most recent releases landed on September 17, 2026 and October 5, 2026 respectively.
