Hi! I'm from Latvia, and was in exactly the same situation. We tried to save money on launching a bike rental app - we took a template, changed colors and added a couple of features. But the further we went, the more limitations. Everything looked the same as a bunch of others. Eventually we switched to custom. We worked with a team through a development company - they just explained the advantages of custom development. Yes, it's more expensive at the start, but then it's flexible, without constant crutches. If the project is serious and you have ambitions, custom development is the way to go.
