Verdict
The clearest difference is in-app purchases: METsTracker at none against ゆるくやせる!'s 7. METsTracker also leads on ads (none vs shown) and update cadence (monthly vs every 8 months). ゆるくやせる!'s advantage is iOS requirement (15.6 vs 26.5). On price and device support there is nothing between them.
