What do you like best?
How easy it is. I mean, you just upload a shot, choose the style of your text, write what you want... and you are done. No weird things, no more options, no more time than the one needed to do something easy... A simple tool to get easy images with text.
Also, being able to share directly to social channels from the app is a great point.
What do you dislike?
Resolution, it could improve and reach the original resolution given by the shot. Right now you get a compressed and low-res image that looks cool on social media tools like Facebook or Twitter, but too small to print or you use on some websites with great retina resolution (it's unfair saying this because Pablo was made by Buffer focusing on social media images, so the low-res can be taken as an "optimized" version for sharing)
Recommendations to others considering the product
If you need a simple, easy and fast app to create images with customized text, Pablo is the way to go. You get what you need to create images for daily use on social media channels, it could get new features, but looks like they update the tool slow... so check it, if fits your needs, well done, if not, maybe you will need to check other app to get what you are looking for as probably won't get an update with new features for several months.
What business problems are you solving with the product? What benefits have you realized?
Getting images customized easily and fast with few lines, which makes a great impact on social media channels.
