Direct answer

Why do development agencies provide such different timeline estimates for similar apps?

Different timeline estimates usually signal differences in scope understanding. Shorter quotes (like 3 months) might exclude discovery phases, rigorous QA, post-launch support, or assume using rigid templates. Longer quotes (like 9 months) often include robust architecture, comprehensive testing, and planning for future scalability—elements that are essential for long-term success but increase initial development time.
