Sensor Activation

I've used Ghostalker for years, and it's unequivocally the best on both the App Store and Google Play platforms. What impresses me most is its consistent performance. Across multiple devices, I've observed that when a sensor triggers in the same way, it consistently generates identical words.

Through extensive testing, it's evident the app's responses are precise and not random. The sensors react exactly as promised, consistently triggering the same words under identical conditions, which speaks to its reliability.

Everything functions exactly as advertised, making it my go-to tool as an enthusiast. It meets all expectations for a smartphone application.

I believe integrating microphone notifications for simultaneous word detections across devices would enhance the app's capabilities. However, I recognize the technical challenges of real-time synchronization and accurate detection across diverse devices. Implementing this would necessitate robust software development, considering hardware capabilities and user privacy. If achievable, it could significantly enhance the user experience, transforming it into an outstanding tool for ghost hunters, researchers, and enthusiasts like myself.

Thank you for developing such a dependable and captivating appโ€”I confidently award it 5 stars!

Response from developer

Thank you so much for your detailed review and the 5 star rating. We are very happy that you like and use the app like other professional paranormal investigators. You are quite right that the app takes a much more scientific approach than other apps, using the real raw sensor data from as many sensors as possible (e.g. vibration, electromagnetic fields, light, proximity etc.) and uses those readings to choose words from it's dictionary. We are proud to confirm there is nothing fake or random about how it works. We will add your feature suggestion to our "wish list" for consideration in future developments. Best wishes to you.

Has no sound

Bought this to see if it would be better than the lite version but words have no sound like the other one

Response from developer

The voice system uses the built-in Apple "text-to-speech" system so should work perfectly in both the lite and full versions of the app. In our tests it works fine. It is possible an iOS update has done something to that particular accessibility feature on your device but we have been unable to reproduce the problem so far.

I love the app but

It's so annoying being taken to your external website if i accidentally tap that button that should really be in the settings. I paid for the app, i don't want sneaky advertisements.

Response from developer

It is a shame you changed your 5 star rating to 1 star. The app does not contain any advertising at all, and does not even require an internet connection to work. I am not sure how we can make the very large text link that says "Visit our website" any clearer that tapping it will cause you to visit our website, but I will add your comment to the list of suggestions.

Disappointed

Just purchased this & no sound, really disappointed that I just got conned

Response from developer

Hi Caz. The app uses the text-to-speech system built into Apple devices (as part of their accessibility features). We have not had any reports of the speech not working so it may be a fault with your device.

Very interesting communication!

Iโ€™ve had some amazing sessions with the free version and am looking forward to the increased word choices to enhance the communication Iโ€™m having with spirit.
