Bolt clone apps can generate revenue in various ways. Some of them are:
Commission on rides: The platform charges a percentage of the total fare from both riders and drivers for each completed ride. This commission rate can vary depending on factors such as the city, time of day, and type of ride.
Surge pricing: During periods of high demand, the platform dynamically adjusts fares to incentivize drivers. It is operated in specific areas to increase revenue.
Subscription Fees: Charging drivers a monthly or yearly subscription fee for access to the platform. Passengers can also subscribe for opting for the premium services.
Advertising: An amount is charged for displaying ads within the app to riders and drivers

And it's link funny that Khazanie mentions NASA because this particular watch has ties to the space program so link strong they rival the Speedmaster. Like the link Speedmaster, it's tested and certified by NASA for space travel. The Passage of Time blog has an excellent entry on all the astronauts who have worn the watch in space. Just to make sure I had the most current info, I checked the Watches Used In Space Exploration database, and it looks like five astronauts have used the Datalink in space.
