Tick reads a cron schedule — those cryptic five fields like 0 9 * * 1-5 — and tells you in plain words when it runs, plus the next five actual run times in your timezone and in UTC. Edit the expression and everything updates live. Nothing is uploaded.

Cron expression (minute · hour · day of month · month · day of week)

minutehourday (month)monthday (week)

Tick understands standard 5-field cron: numbers, ranges (1-5), lists (1,3,5), steps (*/15), and names (mon, jan). Day-of-month and day-of-week combine the way classic cron does — if both are restricted, a run happens when either matches. Seconds fields and special strings like @daily vary by system and aren't included. Everything runs on your device.
