Revenue and growth will be driving factors. How much revenue does it make per month? How many users are added each month? Is your monetization working or not, or do you have other ways to monetize in the future?
For a free app 96k users is not a huge amount but if the growth is strong, maybe you can project what it will be in a year, 2 years.
Anywhere from 3x annual revenue for a stable low growth app, to 5-10x or more for higher growth.
