5 ★ Work as described, it can benchmark all types of memories, internal,SD and ram. Nokia 6.1
3 ★ It works well it would be much more constructive if we could see the sd brand also as well as the phone. If that is not possible to automate the information could be volunteered by user. Thanks
1 ★ What a load of rubbish! Didn't pick up the correct size for SD card, internal memory or RAM. utterly hopeless. Launch a benchmark test, go to results but WHERE'S THE RESULT FOR MY XARX IN MY PHONE???? Loads of other people's results for phones I'm not interested in testing. Uninstaller as quickly as I could.
5 ★ Worked fine for me on my S-4, did exactly what it said it would. Interface is basic, but who cares? It works (& it's free)! Detected & scanned all of my internal drives, including my SD. I haven't tried it on external SDs yet, but so far so good.
3 ★ for me it was confusing as I put to test and the results were not easily displayed. It tends to go to the online results from other devices.... I find this app overrated and some other less known a simpler and more effective solution.
1 ★ Just installed after being very happy with it a year or two ago. Now utter, messy, unreliable rubbish. Won't properly bench my Samsung s7 phone's external sd card anymore, write result 0.0mb/s and missing from the results or corrupted. Did an accurate bench with restart and just as bad. App started recording results then just messed everything up each time I ran it so had to uninstall. Wish I could download the old version !
1 ★ Useless. Showed 0 MB/s write speed after a lengthy thest.
2 ★ The UI was okay but measurement accuracy needs lots of improvement. I was expecting something like GUI for "fio", but got unspecified tests that have results that cannot be correct for my phone. This kind of app should include native libraries and use libaio and direct IO.
2 ★ Very confusing app and it listed my sd card three times. This app contains a huge database of sd cards. I only need mine tested. My results were 1 out of 200 or so other SD cards. I should not have to wade through test results. Not sure what developer is thinking, but this is useless for me and difficult.
1 ★ Describes this is if it's a tool kit or in some way I can actually troubleshoot and solve issues with your storage or SD card but it can't it's simply scans it mysteriously which takes a minute and then tells you it had a cash to read which means you have to click on the link and go to their website and I'm not even going to follow up on that basically they give you a score which is code for benchmark useless
3 ★ Great for comparing my SD card speed to SD cards in other phones. I can tell mine is about average. However it would be better if it could tell me which SD cards the other phones have so I know which ones to shop about for to improve my speed. This really only does half a job.
4 ★ It is a good app. sometimes it shows some "logical" devices, I guess, whose speed it can't measure. Thus can be confusing. Plus, it shows srats fir the world, but does not show those for mt device. But again, it does measure the r/w speed of the sd card when you ask it to, which is good.
1 ★ Already said NO to submitting results online in setting but after test it still pops up and ask to sumbit online. Only one button that does not give option to say no. Also when you go to results, why can't it just show you YOUR results. Who cares what other testers are getting. A compare chart is enough.
5 ★ Does what it says on the tin. For whatever reason, Sony phones top out at 30MB/s. Cheap controllers, maybe?
1 ★ It's okay when you run the test, but once you exit the application the read speed shows 0MB/s, which makes me re-run the benchmark just to double-check the read speed. Fix this and you get 5 stars. Using Pocophone F1.
