Productivity tools remove the small frictions that interrupt a developer’s flow — building cron expressions, converting Unix timestamps, comparing timezones for meetings, doing date arithmetic, counting words, and running a focus timer. Each tool gives an instant answer in the browser, with no account and nothing to install.
These utilities replace the repetitive lookups and calculations that pull you out of deep work. Build and explain a cron schedule with the next run times, convert epoch seconds or milliseconds to human dates and back, plan a meeting across multiple timezones with DST awareness, add or subtract days and compute ages, analyze text readability, and track Pomodoro focus sessions and streaks saved locally in your browser — no sign-in required.
Build cron expressions visually or by typing — with human-readable description and next 5 run times.
Calculate date differences, add/subtract days, and compute ages with working-day support.
Compare times across multiple timezones with live refresh and meeting planner mode.
Analyze text with 7 readability algorithms — Flesch, Fog, SMOG, ARI and more.
Convert Unix timestamps (seconds or ms) to human dates and vice versa — all formats at once.
Count words, characters, sentences, paragraphs — plus reading and speaking time estimates.
Focus timer with short/long breaks, session tracking, and daily streak — saved in localStorage.
No. The Pomodoro Timer tracks your focus sessions, breaks, and daily streak using your browser’s localStorage. No account, login, or server is involved.
Yes. The Cron Builder produces a human-readable description of any cron expression and shows the next five run times so you can confirm the schedule is correct.
Yes. It converts Unix timestamps in both seconds and milliseconds to human-readable dates and back, showing several common formats at once.
Yes. It compares times across multiple IANA timezones with daylight-saving adjustments and a meeting-planner mode for scheduling distributed teams.
