As an AI language model, I don't have real-time data. However, as of my last knowledge update in 2021, there are numerous loan apps available in Kenya. The exact number is difficult to determine as new loan apps enter the market and existing ones may be discontinued or updated. Popular loan apps in Kenya include Tala, Branch, M-Pesa, Timiza, KCB M-Pesa, and many others. It's always recommended to research and compare different loan apps before choosing one that fits your needs.
