That it does. Poke around for promo codes too. Someone sent me one a little while back and I basically got a year and a half’s worth of time added onto my current premium subscription. Some are one-time use (if your friends get one for hitting milestones, they can share those). But there were a couple of public ones a month or so ago too, and I think they’d add another 3 months at least.

I’ve not used Instagantt. For Gantt charts I like TomsPlanner.com. I don’t use them on a daily basis though, so haven’t tried integrating with Todoist in any way (I’m fond of the Tom’s Planner interface though so probably wouldn’t). I use them more for long-term publishing planning and campaign planning.

Have you tried working Instagantt with the app? I attempted it for a little while, but being that I spend more time on my devices than the laptop/browser, it became kind of useless. But given your big schedule and pristine organization skills, I think it could be useful for you!
