Caltrain+ is a Caltrain schedule and trip planning app that lets you quickly and easily figure out which train to take to get you from Station A to Station B. Additionally you can view full timetables, service alerts, and a system map all from within the app. To use Caltrain+, simply select the station you want to depart from, the station you want to arrive at, and the timetable (Weekday or Weekend), and Caltrain+ will show you a complete list of every matching train you could take along with its number, service type (i.e. Local, Limited, Express, or South County Connector), departure and arrival time, and trip duration. Optionally specify an “arrive by” time to filter the list of trains to only include those which will get you to your destination station before the specified time. You can also view the full list of scheduled stops for a particular train just by tapping on it. Transit data provided by 511.org. Icon made by Freepik from www.flaticon.com.

Verdict
The clearest difference is ratings volume: Caltrain+ at 2K against LetsOverlap's 11. Caltrain+ also leads on rating (4.8 vs 4.6). LetsOverlap's advantage is review sentiment (100% vs 85%) and device support (3 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Caltrain+ holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Caltrain+ has 2K ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 85% of Caltrain+'s written reviews are positive against 100% of LetsOverlap's, so the app with the better star average is not the one people write more warmly about.
Caltrain+ ships an update every 3 weeks, LetsOverlap every 2 weeks. The most recent releases landed on September 25, 2026 and September 20, 2026 respectively.
