Show HN: Time Keep – Location timezones, timers, alarms, countdowns in one place

8•jmbuilds•2d ago
I kept running into this: timer on my laptop, alarm on my phone, timezone / discord timestamp conversion app in a separate tab. Switching between them was a hassle and I wanted to be able to set them up and manage really fast anywhere I was.

So I built Time Keep, it puts world clocks, timers, alarms, countdowns, a stopwatch, breaks, a sleep planner, Discord timestamps, and more into one always open place.

Works without an account or signup. All tools are fully functional immediately. Sign in to save your data across sessions. Pro adds live cross-device sync.

Shared countdown links show the correct time in every viewer's timezone. Built with Next.js, Supabase, Clerk, and Vercel.

Honest question: Do you believe the pro subscription to your product is something you would pay $7/mo for? I find this price extremely high for a very small amount of data synchronized and maintenance costs.

Neat. Can you add "cursor: pointer" to the buttons, would mean a lot

Every timezone app tries to do too much. Curious if this just stays simple or eventually adds the usual clutter.

Like many other time-related websites, this one is also well done, well thought out, and well designed. I find it hard to recall the websites when I need them. This is personal, but unless a website is regularly used, and if I need time to think or look up, I try to go for something on my machine.

The same principle I try to bring up when building something for consumers whose primary objective is something else, and the solution/app is competing with something easy to find, “Can this compete or be faster with pen/paper, or just writing a note to self on WhatsApp?”

The Native Time Apps on macOS are pretty good these days, so I have done away with all sorts of Timezome, Alarm, Timer-related Apps except The Clock.[1]

I think The Clock is just one developer, and I have had the app for as long as I can remember (easily 10+ years). I can do without it and use the native clock to replace most functions, but I like that time slider, which I can use to check the time differences between zones. Settings sync across devices via iCloud. It is just there whenever I need it. It is one of those that you buy once and keep abusing for ages.
