Verdict
The clearest difference is in-app purchases: TIER 3 at none against Shift Calendar's 4. TIER 3 also leads on ads (none vs shown) and update cadence (every 4 days vs every 3 months). Shift Calendar's advantage is iOS requirement (11.0 vs 15.1). On price and device support there is nothing between them.
