Cronwright

Cronwright turns cron expressions into something you can actually read. Build a schedule visually, or paste one you found in a script, and instantly see a plain-English explanation plus the exact next run times — no docs, no guessing, no server round-trip.

Whether you're writing a crontab entry, a Kubernetes CronJob, a Quartz trigger in Jenkins, or an AWS EventBridge rule, Cronwright speaks your dialect. Every calculation happens right on your device, so nothing you type ever leaves your phone.

INCLUDED

• Visual builder for standard 5-field cron expressions
• Paste any expression for an instant explanation and the next 5 run times
• Copy the generated expression with one tap
• Save up to 3 schedules to your library

PRO UNLOCKS

• Quartz (seconds + year) and AWS EventBridge dialects
• Unlimited next-run preview, not just the first 5
• Unlimited saved schedules in your library
• Batch validate a whole file of expressions at once
