Verdict
The clearest difference is price: Caesar at Free against Rotational Speed Converter's $1.99. Caesar also leads on update cadence (every 2 weeks vs every 10 months). Rotational Speed Converter's advantage is ads (none vs shown). On in-app purchases, device support and iOS requirement there is nothing between them.
