Verdict
The clearest difference is in-app purchases: TreeChart at none against PDFShare's 2. TreeChart also leads on iOS requirement (11.0 vs 17.0). PDFShare's advantage is ads (none vs shown) and update cadence (every 3 days vs every 5 weeks). On price and device support there is nothing between them.
