Case Study: HOCMAI (Vietnam's leading e‑learning app) achieves 100% install growth and 20% lower CPA with Adjust

How HOCMAI grew double install volume with Adjust and Tik Tok

HOCMAI, Vietnam’s leading e-learning app, needed to reach prospective students on platforms like TikTok but couldn’t separate or accurately measure which channels were driving mobile installs. Free tools produced slow, unreliable reports and left the team without post-install behavior insight for retention and remarketing, so HOCMAI sought a cost-effective, easy-to-use Mobile Measurement Partner with stable long-term data.

HOCMAI chose Adjust Measure to gain clear attribution across campaigns and leverage features like UA overview reports and custom deep links for remarketing. With Adjust’s TikTok integration and responsive global support, the team made faster optimizations, doubling install volume (100% increase), cutting cost-per-acquisition by 20%, and improving CTR.
