What is the best app that you have buy from appsumo ?

The most unexpected purchase that I'm using literally everyday, is Better Uptime. I have like 10+ VPS with a ton of domains and this tool is permanently monitoring them. I also use MainWP, but this tool can monitor many things: my special S3 Glacier backups, sites without Wordpress, etc... I'm amazed, because I can have all in one place.

Second best, Shortpixel. I spent a ton of money on it, have thousands of credits for all my sites.

And my new promise is Long Tail Pro. It is extremely expensive LTD, but is one of the best KW research tools in the market nowadays. I've purchased the Tier 4 for 50K keywords monthly and I've stopped my subscription to other KW Tools I use like Mangools ($30/mo). I'm thinking on paying the last $200 for the Tier 5 and I may probably go for it.

Although is an underrated tool, people like me, that have been in SEO for ages, know what is LTD. It is in the champions league of the keyword research tools like Ahrefs and SEMRush. It's not like many other $70-100 LTD that are appearing constantly in Appsumo, but their quality is s***t

Yesterday, I bought Amelia, a booking plugin. Haven't used it but learnt about this on the facebook bricks community. They have a LTD at a bargain price compared to regular price. Hope that helps.
