Verdict
The clearest difference is price: Pipe Tools at Free against Chaptr's $2.99. Pipe Tools also leads on ratings volume (20 vs 2). Chaptr's advantage is in-app purchases (none vs 1) and update cadence (every 6 weeks vs every 36 months). On ads, device support and iOS requirement there is nothing between them.
