Most travel apps help you book flights or find inspiration. TripSlap solves the messy middle: "I have 5 days in London — what do I actually do each day, and what will it cost me?"
PLAN EVERY DAY IN SECONDS
Build each day as a stack of activity cards — name, time, price, location, and type. Drag to reorder, edit in place, done. Shifting your trip dates? Your days move with them, and nothing gets lost: extra activities land in a dedicated Backup tab instead of disappearing.
AN HONEST BUDGET, ALWAYS VISIBLE
Every activity price and daily transport cost feeds a live budget — totals per day and per category (food, transit, culture, and more), plus lodging and flight costs. Traveling abroad? See the running total converted to your home currency with live exchange rates.
SEE YOUR DAY ON THE MAP
Every day's activities appear on the map, with route optimization that untangles a zigzag day into a walkable one.
AN AI THAT EDITS YOUR PLAN
Ask the assistant to suggest, add, edit, or remove activities — it acts on your itinerary directly instead of just chatting. Bring your own API key (Claude, OpenAI, or Gemini); the app detects the provider automatically and stores your key securely on your device.
TRAVEL-DAY MODE
On the day itself, TripSlap highlights today's plan, sends a morning summary of the day ahead, and counts down to your departure.
