Verdict
The clearest difference is review sentiment: Rebel Timer at 100% against Premom's 70%. Rebel Timer also leads on monetization model (free vs free with in-app purchases). Premom's advantage is update cadence (weekly vs every 3 weeks) and chart position (#29 vs unranked). On price, ads, in-app purchases and device support there is nothing between them.
