Verdict
The clearest difference is price: Heja at Free against JamTimer's $1.99. Heja also leads on update cadence (weekly vs every 5 months) and ratings volume (24K vs 9). JamTimer's advantage is in-app purchases (none vs 14) and ads (none vs shown). On device support there is nothing between them.
