Verdict

The call

The clearest difference is review sentiment: 世界のFX at 92% against OG.com's 49%. OG.com's advantage is rating (4.5 vs 2.0) and ads (none vs shown). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

OG.com holds the better App Store score, 4.5 against 2.0. That said, the two scores are not equally well evidenced: OG.com has 2K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 92% of 世界のFX's written reviews are positive against 49% of OG.com's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

世界のFX ships an update every 2 months, OG.com weekly. The most recent releases landed on November 3, 2026 and November 5, 2026 respectively.
