Textgram is the best Android picture quote maker I have found that’s free, loaded with flexible options and minimal ads. Way better than Instaquote and Jusgramm, which seem to be the other two big apps for the same purposes. Ratings and downloads also seem to agree with my opinion.
There are free backgrounds packages with Textgram, but I can’t seem to get them to load right. Still, there are only a handful for free. If you’re going to be making lots of picture quotes like I plan to be, and want variety, they aren’t going to be enough for you. As a result, I have started making my own backgrounds from wallpapers found on the Internet, usually darkening or lightening them up quite a bit so as to be appropriate for crisp text overlay. They weren’t made for this purpose, originally, so it’s not surprising they’re usually not ideal as they were.
