Verdict
The clearest difference is price: Refill Assistant at Free against Nject's $4.99. Refill Assistant also leads on iOS requirement (12.0 vs 15.1). Nject's advantage is update cadence (every 6 weeks vs every 10 months) and review sentiment (57% vs 33%). On ads, in-app purchases, monetization model and device support there is nothing between them.
