It is quite hard for find dim DSO objects especially in areas with light pollution. Typical easy (and costly) solution for the problem is to use GoTo mounts or to do more complicated task, especially for beginner: start-hopping. Find a start near-by and move towards your target. It is quite hard especially in urban areas when not that many stars are clearly visible.
There are many SkyMap like applications that point you to general direction of an object but they suffer from very poor accuracy especially on azimuth (~1-2 degrees for Alt and up to 20-30 degrees for Az)
So I developed a small free open source web application that combines internal motion sensors (gyro) and maps to first align on an existing easy to spot star and than select an object you looking for. The application guides to the desired target by measuring the changes in alt-az - similarly to digital setting circles. The assumption is that also absolute values of the sensors aren't accurate the relative small changes in the values are accurate enough to bring you to a target.

I tested in on my quite low spec affordable smart phone Samsung A31 with Chrome and Firefox and it works quite well - brings you directly to the target. I hopped between different Orion's stars. Hopped from Sirius to M41, M50. from Procyon to M44... with good success. However sometimes my phone's gyro looses accuracy and I need to realign from the beginning.
However before I continue to add more features and improve the application I need to understand how well it behaves with different hardware
1. Does cell phone sensors provide sufficient accuracy to movement?
2. What is reasonable telescope's FOV that works (1.5 deg, 1.2 deg etc)
3. How frequently it fails to work (gyro/gravity sensors goes out of sync)?
It would give me in important feedback to decide to continue with the development and how. I need to know weather application works or not on your hardware (phone + telescope) and if it provides an accuracy that good enough (what is your FOV) - note if applications like SkyMap don't work for you this likely wouldn't work either...
Thank You Very Much.
