See what developers and teams say about testing with LastApp.ai simulators.
Testing iOS apps from my Windows laptop was impossible before LastApp.ai. Now I can test on any iPhone or iPad instantly without buying a Mac.
The instant device switching is a game-changer. I can validate layouts across 10 different devices in the time it used to take to test on one.
No more maintaining a drawer full of test devices. The cloud simulators behave exactly like real devices - taps, swipes, everything feels authentic.
