iPad crashes when using certian app

What app/s are causing this issue?

You own an 8-year old iPad.

It has a very slow CPU, very limited internal RAM.

How much internal free data storage space is left on this iPad?

How many potentially still active apps do you end up leaving in the iOS background app switcher?

How many active website tabs do you leave open in the Web browser?

Tap on the link below to my iDevice/iOS performance/optimisation user tips link.

Slow iPad on iOS 9, 10 or 11! - Apple Community

Try all of these tips and leave each tip active together.

Do not simply try every tip individually, expecting just one tip to be a performance “cure all”.

Many of these tips are designed to work together to help improve overall iOS/iDevice performance.

Also,I would STOP using that over 3-year old Safari Web browser, as it is, probably, not safe and secure to use any

longer, and seek out a third party web browser that is STILL currently being updated and STILL being supported

on iOS 9.3.5.

Here are a few third party web browsers that I know are STILL being updated and supported on iOS 9.

Popular third party, iOS 9 and earlier compatible Web browsers are more quickly dwindling, now.

Older iOS devices and users had about a dozen popular, well known and secure, third party Web browsers to

choose from at one time.

We are down to six, now.

Here’s what’s left.

iCab Mobile Web browser

Dolphin Web browser

Dolphin Incognito Web browser

Snow Bunny Web browser

Private Browsing Web browser

Maxthon Web browser

Good Luck to You!

Discard that app.
