Verdict

The call

The clearest difference is rating: EarthQuake+ at 4.6 against iShindo's 4.0. EarthQuake+ also leads on ratings volume (2.3K vs 3) and update cadence (every 3 months vs every 7 months). iShindo's advantage is in-app purchases (none vs 3) and ads (none vs shown). On price, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

EarthQuake+ holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: EarthQuake+ has 2.3K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 53% of iShindo's written reviews are positive against 45% of EarthQuake+'s, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

iShindo ships an update every 7 months, EarthQuake+ every 3 months. The most recent releases landed on October 17, 2026 and October 29, 2026 respectively.
