Verdict
The clearest difference is in-app purchases: Shuttle Run Partner at none against Interval Timer's 12. Shuttle Run Partner also leads on update cadence (weekly vs every 4 weeks) and device support (3 vs 1). Interval Timer's advantage is ads (none vs shown). On price and iOS requirement there is nothing between them.
