The best features are those that add value to your customers’ lives. Allowing them to access their account information or make a payment, for example, can benefit both parties because it saves time and eliminates hassle. Push notifications about sales events or special offers, loyalty programmes (such as rewards), coupons/discounts, and integrations with social media channels such as Facebook or Twitter are also popular features. To determine what features to include in your app, conduct market research and determine what features are most important to your customers.
