Making a local mobile phone APP is a comprehensive APP, which needs comprehensive functions to attract users in the same city to download. Local o2o, online payment, local forums, convenience information, shopping malls, take-away errands and other low-frequency and high-frequency needs should be taken into account. Where did the APP come from? You can choose to find a technology company to customize, and a customized APP with complex functions may be costly. The cost of purchasing the APP, the cost of maintaining the APP, the subsequent upgrade of the APP, and the promotion and operation of the APP in the local area are all expenses. All these should be taken into account when making a budget. If you don't have that much money and are optimistic about the market of county-level APP, you can find some projects that the same city APP joins as an agent and buy out the exclusive operation rights in your area, so that the money spent on technology in the early stage will be much less, and you can put the funds in the promotion of APP in the later stage. Finally, if you want to start an APP, it is recommended not to use the so-called free template to generate it automatically. The update iteration behind such an APP can't keep up. Promoting such an APP not only wastes your own time, but also wastes promotion expenses.
