It seems that there's no thread about this so I'll share this very useful tool for all of you . First of all, this tool IS NOT MINE. I only posted this so everyone can benefit from this tool. This is pretty much accurate, it can predict when is the time where there is a ton of loot. You can utilize your boosts, spending gems on the right time. You don't want to boost your barracks while everyone has a shield. This tool will avoid that scenario.
