This is hands down the best Roadmap - Timeline app I've found on iOS desktop and mobile and I've been through a few. It is super intuitive and easy to use but also has great power in its more advanced functions like dependancies. I'm planning a Kickstarter campaign which includes a 1.5 year design > prototype > campaign > manufacturing > shipping timeline and after one hour of using Roadmap Planner, was the first time that I actually had a good sense of the entire project. Such a relief. I had tried different methods to achieve the same goal, like spreadsheeting with excel and google sheets and a few other iOS apps like Calendar Timeline that essentially try (but fail) to do the same thing and nothing has come close... Really easy to use, I was up and running in no time. The subscription prices are reasonable and worth it in my opinion to have the sync function across multiple devices. There are a few small bugs that I've reported with their support team who are super communicative and assure me that the bugs will squashed ASAP. I always appreciate good communication from a developer and these guys are great. All in all, if you need to build a timeline for a project, for yourself or for an entire team (great presentation function) then this is your app... Highly recommended.
super easy to use, powerful, great pro functions like dependencies, well priced, easy to sync between devices, great presentation mode
A few bugs, that the developers assure me will be squashed soon
