“You need to have golden moments where you can ask for a rating. In this case it could be when you tap on a stop and see a live tracking of a bus or train — you can actually see it moving on the map. That's a great moment to ask the customer for a rating where the customer is most likely to respond positively.”

Time rating prompts to the app's wow moment, not session start

Rating prompts fire at the exact moment the user experiences the product's core magic (watching their bus crawl across the map live), not on session start or random N-th-launch heuristics. The resulting 75K+ five-star ratings on 5.2M downloads is what feeds the ASO flywheel — once you're top-10 for a keyword, ratings velocity decides whether you reach #1.
