Verdict

The call

The clearest difference is in-app purchases: Graf IoT at none against Timecon's 2. Graf IoT also leads on ads (none vs shown) and update cadence (monthly vs every 12 months). Timecon's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 16.0). On price there is nothing between them.
