How Do You Choose the Right Mobile App Development Company in Toronto?

I'm planning to build a mobile application and am researching how to choose the right mobile app development company Toronto.

What factors matter most when selecting a development partner? Do you look at:

• Previous app portfolio
• Experience with iOS and Android apps
• Communication and project management
• Development cost and timeline
• Post-launch support and maintenance

If you've worked with mobile app developers in Toronto, I'd love to hear about your experience and any recommendations. Your insights could help others looking for reliable Toronto app developers as well.
