Below are some frequently asked questions:
Can i use Backtrix on ios 11/12?
No, it requires ios 13 and above.
Will Backtrix run on ios 14?
Native backtap only supports iPhone 8 and above on ios 14. But with Backtrix, you can use these gestures on your iPhone 6s/7/SE too. If you try to use Backtrix on devices which already supports native backtap, it won't work due to potential conflicts.
What devices does it support?
It requires iPhone 6s and above. In my testing i have found that the number of false triggers was more on pre iPhone X devices. Note that this does not mean that it won't detect taps on pre A11 devices, it just means that it works but these devices accelerometer have different frequencies and hence cause more signal noise which may produce these erroneous triggers. The tweak is not compatible with iPads.
Will it work with a case on?
Yes it does for most cases. But for military style cases (thick or rugged case), it won't.
What is the success rate of the gestures?
More than 85% of the gestures are successfully detected, but false detection can happen too. This is also the case with ios 14 native backtap and even Apple who invest thousands of dollars into research was not able to fully prevent this.
Native backtap feels slow. Is it the same with Backtrix?
Backtrix has 2 sensitivity setting: normal and high. The normal one might feel a bit slow but will result in less false triggers. High sensitivity runs the detector at a higher frequency but at the same time might create false/double triggers and have slightly higher consumption of battery. I suggest to try both for some days to see what suits you best.
Can i use it on lock screen?
No, the actions will not run on lockscreen due to security issues.
Will it trigger accidental backtaps in my pocket?
The tweak can make use of the proximity sensor to ignore any backtaps when the device is placed inside your pocket which is useful for people who put their phones in their pockets without locking it first. Do note that having the proximity sensor always on might impact battery life on older devices.
Does the shortcuts run inline?
No, it open shortcuts app and runs the shortcut.
