Verdict
The clearest difference is in-app purchases: Light Signals at none against Kinly's 2. Light Signals also leads on update cadence (weekly vs every 3 weeks). Kinly's advantage is ads (none vs shown) and iOS requirement (17.0 vs 26.1). On price and device support there is nothing between them.
