Frill is well suited for beginner or mid-level startups looking to get customer feedback on their products. If a business has a really well-suited product pipeline filled with features and is confused which one to build first, Frill is a really nice platform/product to have. You can get direct customer feedback and you can finally work on things that matter the most. It is less appropriate for someone who doesn't have a big product feature pipeline or roadmap in their mind.
If you do web programming, code integration with your remote team, and/or software development that requires real-time monitoring of development progress, monday dev is an excellent tool for this. Like its base platform, Monday.com, monday dev is developed and attempts to integrate into a very "new era" organizational system of digital whiteboards, only now focused more on productivity and helping developers to be comfortable in remote work.
While monday dev is an excellent ally to organize and work in harmony with your team, there are still certain important aspects that need to be improved. They are minor, but if corrected, they will help improve the user experience when using it.
Monday is better than Jobber, as it gives you a place to see where all the jobs are and what the current status is. Everyone in the company can go to and see that view. It's not dependent on the status of the employee. Excel is much more technical and requires much more work to set up.
