Verdict
The clearest difference is price: REVIAN® at Free against Nject's $4.99. REVIAN® also leads on iOS requirement (12.0 vs 15.1). Nject's advantage is rating (4.0 vs 3.7) and chart position (#10 vs unranked). On review sentiment, ratings volume, 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
REVIAN® is free to download; Nject costs $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Nject holds the better App Store score, 4.0 against 3.7. Both are backed by a comparable volume of ratings — 46 and 126 respectively. Written reviews complicate that: 63% of REVIAN®'s written reviews are positive against 57% of Nject's, so the app with the better star average is not the one people write more warmly about.
REVIAN® ships an update every 3 months, Nject every 6 weeks. The most recent releases landed on September 19, 2026 and September 23, 2026 respectively.
