Which is better, RentalFlow or BookThatApp?
It depends on what you book. Pick RentalFlow if you rent physical products that you deliver and pick up. Its booking form asks for drop-off and pickup addresses, and its dashboard shows each day's deliveries, pickups and returns. Pick BookThatApp if you also book appointments, classes or time slots, or want group bookings where several customers take the same slot. RentalFlow books whole days only and does rentals, nothing else.

Where RentalFlow wins
Built for physical product rentals. BookThatApp covers appointments, classes, tours and rentals. RentalFlow focuses on renting physical products you deliver and collect, so the form asks for addresses and the admin is built around drop-offs and pickups.
A stock check before the cart. Some BookThatApp reviews mention the app accepting bookings beyond set limits. RentalFlow checks your Shopify stock against every overlapping booking when the customer clicks Add to Cart.
Simple setup. BookThatApp reviews often mention complex configuration. RentalFlow installs from the App Store, and you add its block to your product page in the theme editor.
Delivery and return management. RentalFlow tracks deliveries, pickups, return counts, damage and lost items. BookThatApp handles bookings, and the delivery side is up to you.
Works on your phone. Some BookThatApp reviews mention slow pages and a mobile calendar that resets. RentalFlow runs inside your Shopify admin, so it works in the Shopify mobile app and phone browsers.
Where BookThatApp wins
Versatility. If you need appointments, classes, tours and product rentals in one app, BookThatApp covers all of them. RentalFlow only handles product rentals.
Hourly and group bookings. BookThatApp supports hourly time slots and group bookings. RentalFlow books by date.
Lower entry price. BookThatApp has a free plan for 10 bookings, and its Lite plan is $25 a month for up to 50 bookings a month. Compare that to RentalFlow's flat monthly pricing.
Larger user base. 418 reviews with a 4.7 rating mean a longer track record and more community knowledge.
Text messages and deposits. BookThatApp's Premium plan ($49.95 a month) and up can send text messages and take deposits. RentalFlow doesn't send reminders or take deposits.
Who should choose which?
Choose RentalFlow if you rent physical products and need to manage the whole cycle: booking, delivery, return and damage tracking.
Choose BookThatApp if you need a general booking system that handles more than product rentals, need hourly time slots, or run a service business alongside your rental stock.
Is RentalFlow the best alternative to BookThatApp?
For physical product rentals that you deliver and collect, RentalFlow is worth a look. BookThatApp is a versatile booking tool, but some merchants renting physical products report overbooking issues, complex configuration and mobile calendar bugs in App Store reviews. RentalFlow is built for the rent, deliver and return cycle. Read more in our guide to BookThatApp alternatives.
