Let SaturnMoons guide you to observing Saturn’s complex system of rings and moons. Sky & Telescope’s latest app helps you locate Saturn’s nine largest moons with a pinch-zoomable interface set to your local time, guiding you to Saturn’s largest moon, Titan, or helping you try your luck with the fainter moons. The time controls allow you to step through the seconds or hours, or speed through days or even years to see where the moons will be down the line. And you can flip the view to customize what you see through your telescope. Plus, our full encyclopedia section contains fascinating entries and stunning images of Saturn’s bizarre lunar family. Learn more about Saturn’s “death star” moon, Mimas, two-faced Iapetus, and the salty ocean frothing beneath Enceladus’s surface. Please note: this application is designed to work in landscape orientation only so that you may view Saturn, Saturn’s rings, and the lunar family at their best.
Moonbound

Moonbound tells you what is worth looking at on the Moon tonight. Open it and you see the sky as it really is: the Moon where it sits on tonight's pass, how high it is, which way to face, and how much of it is lit. Drag across the sky to see where it will be later on. Below that are the sights worth your time tonight, picked from the way the Moon is lit and tilted right now. Each one tells you why tonight suits it, where to find it on the disc, and what happened there. The next seven days are one tap away, so you can tell whether to go out tonight or wait for a better night. Also inside: A catalogue of 40 classic sights, from the dark seas you can pick out with binoculars to craters and valleys that need a telescope A compass that points you to the Moon A red light mode that keeps your eyes used to the dark An alert on the nights that are genuinely special, when the light falls just right on something worth seeing A camera view to help you line up a photo through your telescope All of that works without paying. Moonbound Pro adds the 14 harder sights: telescope targets, the Apollo landing sites, and the seas that only swing into view when the Moon tilts the right way. Monthly, yearly, or buy it once and keep it. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is price: Moonbound at Free against SaturnMoons's $2.99. Moonbound also leads on update cadence (fortnightly vs every 26 months). SaturnMoons's advantage is in-app purchases (none vs 3) and device support (3 vs 1). On ads there is nothing between them.
