Book refundable rooms, then keep the cheapest.

Bookings from any site work. Every booking gets its place in your trip, sits beside other bookings for the same nights, and gets a reminder before its free cancellation deadline. On supported sites Rueless also does two more things: it fills in the details from your link, and it checks the price. From other sites, you enter the details by hand.

Yes. Rueless is free during the public beta, and there is no paid plan.

Refundable rooms cost nothing to hold until their deadline. Keep your first room while you decide, book a cheaper one when you find it, and cancel the other in time. If the price of a room you booked drops on a supported site, Rueless emails you, and you can rebook it at the lower price and cancel the original. Rueless shows which costs less and reminds you before each deadline, so that you do not pay for both.

No. You cancel on the site where you booked. Rueless has no access to your booking accounts and does not need your passwords.

Paste the link of the hotel page or the checkout page from a supported site. You can also add the Rueless bookmarklet to your bookmarks bar and click it on the booking page. For other sites, enter the details by hand.

A calendar reminder knows nothing about your other bookings or the price. Rueless keeps your bookings from every site in one place, puts bookings for the same nights side by side, emails you 24 hours before each deadline, and on supported sites tells you when the price drops.

Only when the same room, dates and guest count cost less than you paid, on the same tax basis. If one of these is different, the check shows "Not comparable" and no saving.

When you add a booking, Rueless compares what you paid with the public price at that time. The difference is your discount, such as a member price. Each price check takes today's public price for the same room, dates and guests, and applies the same discount. It is an estimate, not an offer, so confirm the price on the booking site before you rebook.

The booking link you paste or send with the bookmarklet, and the details Rueless reads from it or you enter: hotel, dates, room, guests, price and free cancellation deadline. Rueless never asks for your booking site password or your card number.

You can add it, so the trip shows every night. It has no deadline to watch and no lower price to act on, so Rueless only keeps it in view.

No. Rueless does not hold flights or plans. It holds your refundable hotel bookings until you choose which ones to keep.
