Verdict
The clearest difference is review sentiment: EPiC at 100% against Energy Viewer's 40%. EPiC also leads on rating (4.5 vs 2.0) and ratings volume (27 vs 4). Energy Viewer's advantage is iOS requirement (11.0 vs 17.4). On price, update cadence, ads and in-app purchases 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
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
EPiC holds the better App Store score, 4.5 against 2.0. That said, the two scores are not equally well evidenced: EPiC has 27 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 100% of EPiC's written reviews are positive against 40% of Energy Viewer's.
Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 24, 2026 and October 21, 2026 respectively.
