2024-09-30 | Philippe Daniel Serrano (Daniel) | ☹️ I know that the dev did great with all the other features BUT I bought this app specifically for the "test+verify" feature which does NOT seem to work as accurate as "H2testw" on Windows. ❌ 🤔 Idk if this is an Android limitation/issue or if this could be resolved by the dev on their end. | |
2024-09-29 | Bence Tóth | Excellent application! Detailed, with thorough explanations. Love your work, Zoltán! | |
2024-09-11 | Duane 'Dee' “Dee” Chatwin Jr | An app that finally works, so well done to the creators of this app. | |
2024-07-16 | A Bdour | Yes, it does what it is intended for, however I wish the developers add an option to label the results ..... super app. | |
2024-06-18 | Frank Wojtczak | I like the app quite a bit, it does a lot of good testing. There is, however, one problem with it: It stores all of its test data on the internal storage of the device. this will really cramp the space you have available. there should be an option to store it only internally TEMPORARILY! Otherwise, the only option you have to get rid of that data is to uninstall the app. Not good planning. | |
2024-05-24 | Andrew Anderson | Really good app people and not very much money for pro version too and its really easy to use aswell people love the app alot bigtime like people i was haveing hassles with my SD card moveing apps over to it and ran the read then write tests and the app fixes problems too bigtime 5 stars and more honestly people | |
2024-01-30 | Norm L. | Before purchasing, this was suppose to run in the background. I started Verify Written Data and left the app (not closed) worked on other apps. But when I come back after a short while, the app has stopped running. No results. Large 256GB card. MISSED THE REFUND WINDOW. APP DOES NOT WORK IN THE BACKGROUND! | |
2022-11-30 | kamal venugopal | App is simple to use and if the graph is shown while testing would be visualised apppeal | |
2022-07-09 | Rich Consigna | My Samsung Evo Plus 256GB Micro SD Class 10 UHS-I U3 V30 A2 that i bought from samsung official store write speed drop from 51mbps to 14mbps after full write and read test | |
2022-07-01 | raclapp12 PRIVATE | Excellent but would add one item of data. With all the minor changes between device variants (see Samsung Galaxy tab s7 plus models for example) .. I would like to see a rating & info for the embedded device card reader. UHS type, etc. It impacts speed rating of the cards tested. Would allow for debugging minor discrepancies for same card across devices. Would also like to see other OS versions... |
