Verdict
The clearest difference is in-app purchases: InterTimer at none against Justfit's 5. InterTimer also leads on ads (none vs shown) and iOS requirement (13.0 vs 15.0). Justfit's advantage is update cadence (every 3 days vs every 27 months). On price, review sentiment and device support there is nothing between them.
