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. — WHAT MAKES CRONWRIGHT DIFFERENT — • Visual builder. Build standard 5-field cron expressions visually, or paste any expression for an instant plain-English explanation and the next 5 run times. • Multi-dialect support (Pro). Speaks Quartz (seconds + year) and AWS EventBridge, in addition to standard cron. • Unlimited run preview (Pro). See unlimited upcoming run times, not just the first 5. • Fully offline. Every calculation happens on-device — no account, no ads, no analytics. • One-tap copy and a saved library. Copy the generated expression with one tap and save schedules to your library. — PRICING — Cronwright is free, offline, with no account, no ads, and no analytics. The free version includes the visual builder for standard cron expressions, instant explanations with the next 5 run times, one-tap copy, and up to 3 saved schedules. Cronwright Pro is a one-time purchase (no subscription) that unlocks the Quartz and AWS EventBridge dialects, unlimited next-run previews, unlimited saved schedules, and batch validation of a whole file of expressions at once. — FEEDBACK — Made by a small indie team.
