Great concept, but issues

Ive been using the app since day 1 and Ive been active daily. I love the questions-lead social networking... learned a lot about my friends. Some things need to be fixed though:

-Battery life. Even with low-power mode on my phone is draining much of the power from it. Battery settings confirmed it.
-Emoji needs to be bigger. I can barely see some of the emojis because they look mini.
-Crashes. Not very often but Ive been seeing it every couple days or so.
