Of all of the MANYMANYMANY cute dating sims & visual novels on iOS, I think NTT Solmare is up there as one of the higher-quality publishers releasing them! Here’s a big honkin’ list of the games they have available~

NTT Solmare has two versions of many of their games – the ones with a “+” at the end can be played entirely for free, although there are grindy portions of the game where you’ll need to raise stats in order to progress through the storyline.
In the non-“+” versions, you only have to buy the route you want to do, then you can play without restrictions or interruptions. Pick the play method you like better!

Hope to pretty this up with images and descriptions in time.
