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.
QuestCircle

Find something real to do this weekend. QuestCircle is where you discover local experiences run by real people — a sunrise trek, a pottery afternoon, a street food walk through parts of the city you have never seen. Not a list of places. Things that actually happen, with someone showing you. DISCOVER WHAT IS NEAR YOU Open the app and see what is happening around you, sorted by how close it is. Pick a day, switch to the map to see everything at a glance, or filter by price, distance, or the kind of thing you are in the mood for — treks, food, art, music, wellness and more. BOOK IN SECONDS Found something? Book it and pay over UPI in a few taps. Your seat is confirmed straight away, and you get the host's number and the exact meeting point so you can sort out the details directly with them. Some quests are free — those you simply join. EVERYONE ON THE QUEST, IN ONE CHAT Every booking puts you in a group chat with the host and everyone else going. Ask what to bring, say you are running late, find each other at the gate. When it is over the thread stays open for a day so you can say thanks and swap photos. MEET THE PEOPLE BEHIND IT Every experience has a host — someone who knows the thing they are showing you. Read what previous guests said, see their rating, and subscribe to the ones you like so you hear about what they are running next. HOST YOUR OWN Know a route, a recipe, a skill, a corner of the city worth showing? Anyone can host. Set your price, set how many people can come, and QuestCircle handles the bookings and the payments. Track what you have earned in your creator studio. BUILD A STREAK Every quest you book earns XP. Level up, collect badges, keep a daily streak alive, and see where you land on your city's leaderboard. It is a small thing that makes going out feel worth it. KEEP TRACK OF EVERYTHING My Quests holds the ones you are going to, the ones you have hosted, the ones you saved for later, and everything from the hosts you subscribe to. BUILT TO BE SAFE Report or block anyone from their profile. A block is immediate and works both ways — you disappear from each other's view. Everything you post is yours, and you can delete your account from inside the app at any time. WHAT YOU NEED A phone number to sign in. Location access is optional — the app works without it, you just will not see what is nearest.
