Beyond Pricing & Wheelhouse are great
I've used HostTools, Beyond Pricing and Wheelhouse. I found all of them to be extremely useful, but you will always have to make adjustments to their logic, every property is different and offers different amenities.
Beyond Pricing connects with Airbnb and HomeAway/VRBO, Wheelhouse only connects with Airbnb, but if you use a channel manager you can push your Airbnb rates and minimum stays to Homeaway and save yourself the commission.
I currently use wheelhouse, simply due to cost. Beyond pricing was costing me about $180/month, Wheelhouse costs me about $90, lower commission fees, and no charge for HomeAway. If you don't use a channel manager that can push your Airbnb rates and minimum stays to HomeAway, then Beyond Pricing would be a better option.
These tools are great for managing your rates, but you need to tell the tool the correct base rate. Once you have found your ideal base rate, the tool will increase your rates according to demand, and do last-minute discounts etc...
The most valuable feature for me is the ability to dynamically adjust your minimum stays to close gaps or to get extra bookings when time is running out. Both Beyond Pricing & Wheelhouse do a great job of doing this.
