Verdict
The clearest difference is ads: Olivia Auth at none against Dev Tool box's shown. Olivia Auth also leads on iOS requirement (15.0 vs 18.0). Dev Tool box's advantage is update cadence (every 3 weeks vs every 4 months). On price, in-app purchases and device support there is nothing between them.
