Verdict
The clearest difference is in-app purchases: Zen Pi at none against Flip Timer & stopwatch's 3. Zen Pi also leads on ads (none vs shown) and rating (5.0 vs 4.6). Flip Timer & stopwatch's advantage is ratings volume (7.6K vs 2) and update cadence (every 3 months vs every 7 months). On price, device support and iOS requirement there is nothing between them.
