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 One-time purchase, no subscription. No account, no ads, no analytics — Cronwright works completely offline. Terms of Use (EULA): https://obelisk.club/cronexpressionbuilder/terms
