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.
It is a little short of tutorials, I know that the platform is very easy to use but sometimes there are little things that I had not understood.
The output of the route sheets is very limited, I would prefer that this could be customized.
There are times that there is a little space between the bars of the roadmap, I would like this to be automatically coupled and thus have no errors between dates or time when a task will be performed after completing another.
ProductPlan has given better results without much effort in learning to use the software itself since other platforms have been very complicated and the ROI was not very pleasant compared to this platform. With ProductPlan work efficiency has been increased since workflow management has been brought to a level that can be more organized without setbacks.
