Some people want the smallest device that does the job. Others want to see what they are tapping. Both are legitimate, and the software should not have an opinion.
zInspector's position is that you should have options when performing inspections, and one of the ways that gets honoured is by letting users decide which mobile device works best for them. Some inspectors are most comfortable with a smartphone and the smaller the better. Others prefer the larger buttons and display a tablet gives them.
That second group is not being fussy. Over a forty-detail walkthrough, target size and legibility decide how tired you are by the end and how many mis-taps you have to undo.
On an iPad mini or a standard-sized iPad, inspection is especially convenient: you keep the easy portability of a mobile device while gaining the larger buttons, screen and interface that some people prefer and others genuinely require.
zInspector 3 supports contemporary operating systems on both sides, namely iOS 9.3 and above and Android 5.0 and above. Whether you use an Android smartphone or an iPad, property inspection is within reach and the records are identical. The iPad app page goes into how the interface adapts.
Both work well. The mini is easier to hold one-handed for a long walkthrough; the full-size iPad is better if legibility is the reason you chose a tablet in the first place.
Yes, and most do. One inspector on an iPad and another on an Android phone produce the same record against the same property definition.
For inspection documentation, comfortably. The in-app camera is tuned for report-grade output rather than for photography, and the larger screen makes it easier to confirm the shot before moving on.
