I tried using https://cal.com for a bit but ended up just switching over to https://zcal.co and it has been great so far. All these other scheduling tools end up trying to do too much and always seem to end up a bit clunky and charge absurd amounts for it

20 Telegram Alternatives to Chat With in 2024

  • Fellow HSP entrepreneurs, how do you manage your energy and stress?
    I force clients who want to talk to me to book a call. I use cal.com (free) and my Google Calendar (which its linked to) only allows calls on specific days/times. I have a few "Call Blocks" where they can book. That let's me do calls in a small section of my week, with ample downtime to recover the rest of the week. I'm still learning how many calls a day I can handle. Currently anything more than 2 is too much. Source: 6 months ago

  • User-facing/client-side tools for internet troubleshooting
    Hi everyone. The other day a client of mine's employees started having issues with the "internet not working". After some detective work with traceroute and interviewing them about what sites they were having issues with, I determined that the actual issue was with the web.whatsapp.com service having downtime. I'm mentioning all this because I'm now thinking of making them a small video/article on our intranet... Source: 6 months ago
  • Is WhatsApp Web down in Oman?
    I believe web.whatsapp.com is being blocked by local telecom companies in order to protect their duopoly and keep Oman in tech--stone-age. If fewer people know how else the rest of the world uses the internet, then they don't have to make an effort to improve their offerings. Omantel is definitely blocking this web.whatsapp.com.
