Yeah - however IMO large growth isn't as important until some semblance of PMF is hit with a few core users.
Then can treat the other platform as a marketing cost - i.e. if you're making 75k on iOS and predict a similar revenue for Android it's worth it to hire an Android developer for to build it out. But if one hasn't yet found a few hundred quality users on one platform why build the other one.
