CircuitShepherd provides you with analog-design superpowers by doing automated parameter optimization it in realtime! It's a novel Electronic Design Automation software for AI driven electronics circuit engineering. You define an arbitrary schematic including specific design goals and CircuitShepherd will find the right part values for you. This is achieved by combining traditional circuit simulation techniques with AI driven parameter estimation algorithms and finally a simple and intuitive user interface. It’s easy to learn, fast to use and it will save you a lot of time by automating your daily calculation and iteration tasks. CircuitShepherd is free to use immediately (with very basic features). The full version with all features enabled is available via in-app purchase (subscription-based).

Verdict
The clearest difference is in-app purchases: Horizontal PCB at none against CircuitShepherd's 1. Horizontal PCB also leads on update cadence (every 5 days vs every 3 weeks). CircuitShepherd's advantage is iOS requirement (14.0 vs 26.0). On price, ads and device support there is nothing between them.
