flow is the only to-do list app you need for your life. Unlike GTD, flow believes we only need to types of to-dos: things we want to do right now (flow), and things we want to save for future (future).
For example, flow may include to-dos like sending an email, or making a phone call. On the other hand, thing like making a travel plan, or taking exercises everyday can be categorized into future. Sometimes we need to delay some to-dos (e.g. something pending for others response), then we can simple move it from flow into future.
You can customize the emojis for those categories as well :)
