Write Once

Write Once is a minimal daily writing app built around one simple idea: one blank page, once a day. Start a session and write freely for fifteen minutes. There are no feeds, prompts, streak pressure, or public profiles. The timer stays out of the way so you can focus on the page. Your writing is stored locally on your device. Use Write Once to clear your head, build a small writing habit, or capture whatever is on your mind before the day moves on.

Verdict
The clearest difference is iOS requirement: Write Once at 17.0 against ZenSlate's 26.0. On price, ads, in-app purchases and device support there is nothing between them.
