Verdict
The clearest difference is price: ComposePocket at Free against Pistoneer's $0.99. ComposePocket also leads on update cadence (every 5 days vs every 11 days). Pistoneer's advantage is ads (none vs shown). On in-app purchases, device support and iOS requirement there is nothing between them.
