# FidoLED vs ROE Calculator

The clearest difference is price: ROE Calculator at Free against FidoLED's $2.99. ROE Calculator also leads on update cadence (every 6 weeks vs every 5 months) and review sentiment (100% vs 83%). FidoLED's advantage is rating (4.8 vs 4.0) and ratings volume (18 vs 1). On ads, in-app purchases, device support and iOS requirement there is nothing between them.

ROE Calculator is free to download; FidoLED costs $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.

FidoLED holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: FidoLED has 18 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 83% of FidoLED's written reviews are positive against 100% of ROE Calculator's, so the app with the better star average is not the one people write more warmly about.

FidoLED ships an update every 5 months, ROE Calculator every 6 weeks. The most recent releases landed on September 24, 2026 and June 1, 2026 respectively.
