I have been using Instagress for about 2 months now and I am pretty pleased with the results. I did my 3 day trial and I purchased 90 days for like 25$ i think it was. Their packages are not based on consecutive days, rather, 90 FULL days of use. When you are using automation, you will be turning the bot on and off throughout the day to keep it looking humanistic so only when the bot is running is when your clock for paid time is. So realistically 90 days is much more since the bot is not running 24/7. I mainly use it for my main IG account but I have created 3 other niche profiles that you are allowed to allocate time to as well. Pros: It works, Cons: It's slow. Even on the fastest setting that you run the automation (around 960 likes, 240 comments, 624 Follows, 480 unfollows per day) you cannot make it work any harder than this limit. Now, this can be a pro in the sense to the safety of your account considering it will generally never hit any spam limits that IG might flag. As long as you set up a heavy amount of pre-made comments, you will not get comment blocked or liked blocked ever. Your profile will never follow/unfollow too many people either. Another con is it cannot target gender, which I would only use in certain circumstances if given the opportunity but I don't have that option with Instagress. Besides it being Safe/Slow and not being able to target gender, I would say Instagress is a great automation tool for beginners and anyone just looking to maintain a safe form of automation.
I have never used massplanner but I read they have much more advanced settings but I have also heard of many people getting caught up in the spam filters one way or the other because they don't know how to properly time out the executions. But I'm sure if you google how to maximize it or even ask BHW you will find information.
If you do go with Instagress you can PM me and I will gladly tell you how I have been using it to maximize it's potential.
Hope this helps!
