I also sometimes place bets right before a match. My favorite bookmaker, 1xbet, helps me with this. Check out 1xbet download ios here. Live betting is very convenient with it, and the lines and odds update almost instantly. I usually bet on goals and the first 30 minutes, as these are the most dynamic markets. A couple of weeks ago, I got odds of 2.7 using this method and made a good profit. The interface on my phone allows me to switch between matches and markets without wasting time.
