MobiDev vs Tallium: overview

MobiDev

Mobile apps with an applied AI or computer vision component are MobiDev's specialty, delivered from R&D centers in Poland and Ukraine under a company incorporated in both the US and UK since 2009. The company has built a visible specialization in mobile app development and computer vision work for startups and mid-size product companies. That dual-country R&D structure spreads delivery risk but means, like several peers, Ukraine is a delivery location rather than the company's registered domicile.

Tallium

A published hourly rate is what sets Tallium apart on this list: $25-$49 per hour per GoodFirms, backed by a 5.0-star rating across more than 40 verified reviews, out of a company founded in Kyiv in 2012. That published rate is unusual among the companies reviewed here, most of which don't disclose pricing publicly, and it makes Tallium a genuine cost-transparency option for smaller buyers. Its boutique scale suits single-team engagements better than very large, multi-team enterprise programs.
