Verdict
The clearest difference is in-app purchases: Desmos Graphing Calculator at none against Anchor's 2. Desmos Graphing Calculator also leads on chart position (#185 vs unranked). Anchor's advantage is update cadence (every 4 days vs every 2 months). On price, ads, device support and iOS requirement there is nothing between them.
