The clearest difference is price: TheFlex at Free against KnowledgeBase Builder's $8.99. TheFlex also leads on iOS requirement (13.0 vs 15.0). KnowledgeBase Builder's advantage is in-app purchases (none vs 2) and update cadence (fortnightly vs every 6 months). On ads and device support there is nothing between them.
