About
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.
