My suggestion is to focus on the user experience of one phone per game, rather than one phone per player. This way the players can pass that phone around as a marker of who's bet it is. When it's your turn, you look at the phone, see your chips, make a decision, place your bet, then pass to the next player.
Bonus points if you tie this into a tracking system and let players create leaderboards they fill over time.
