Verdict

The call

The clearest difference is price: CallBell at Free against TimerMonitaring's $1.99. CallBell also leads on iOS requirement (15.6 vs 18). TimerMonitaring's advantage is ads (none vs shown) and update cadence (monthly vs every 21 months). On in-app purchases and device support there is nothing between them.
