Strategy games that actually work on a phone
Strategy on mobile has a reputation problem, mostly because too many games cram desktop interfaces onto a phone and hope for the best. The good ones design around the touchscreen instead of fighting it.
What I look for first is readability. Can I tell what's happening at a glance, and are the tap targets big enough that I'm not misclicking a unit into disaster? Iron Tide Command gets this mostly right, though even it wants a bigger screen.
The second thing is pacing that respects a phone session. Turn-based games win here because you can think, put the device down, and resume without losing the thread. Real-time strategy tends to punish interruptions, which is exactly what phone life is made of.
My advice: start with the tutorial missions even if you're a genre veteran. Mobile strategy games often invent their own shorthand for commands, and the first campaign chapter is usually where they teach it.
