company provides seafarers for ships, including roles like captains, engineers, deckhands, and stewards.

I like the integrations with SMS and with my cheduled meetings. Makes communications with a small team really easy

This is the best app yet to keep in touch, brainstorm, schedule, and keep people in a group informed on what's happening and what's next. It not only has painless group/individual text messaging capabilities, but you can also record and send voice messages and even videos! I used it to send a short instructional of myself setting up a rather complicated piece of software, and people were able to replicate the algorithm. You can post schedules, schedules of shifts, etc. For the unpaid version, you are limited to 10 ppl per group, for paid is unlimited. Also, for the paid version you may have multiple admins. Also, you can use across multiple platforms: Android, iOS, Windows, and multiple devices per account, in parallel.
