Verdict
The clearest difference is price: Epoch X at Free against SidePilot's $13.99. Epoch X also leads on review sentiment (100% vs 57%) and update cadence (every 3 weeks vs every 6 weeks). SidePilot's advantage is rating (4.0 vs 3.0) and in-app purchases (none vs 2). On ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Epoch X is free to download; SidePilot costs $13.99 up front. Epoch X sells 2 one-off in-app purchases. SidePilot asks for nothing beyond the download.
SidePilot holds the better App Store score, 4.0 against 3.0. That said, the two scores are not equally well evidenced: SidePilot has 98 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 57% of SidePilot's written reviews are positive against 100% of Epoch X's, so the app with the better star average is not the one people write more warmly about.
SidePilot ships an update every 6 weeks, Epoch X every 3 weeks. The most recent releases landed on September 20, 2026 and September 14, 2026 respectively.
