I work with 3 different countries and the time difference always confuses me. Usually I have to Google it and check and recheck one by one. That’s tough. I really wish there is an option with the time difference) ### 3/5 — Does the job *2022-10-12, version 4.1.2* It does the job. Would be better without ads spamming the bottom of the screen. ### 2/5 — 汇率不准 *2022-04-28* 汇率不准 ### 5/5 — Can’t convert from tons to kilos *2022-04-01, version 4.1.2* Love this app, so convenient! BUT found out one bug… it doesn’t convert from tons to kilos. I added 26.168 in tons and in kilos the number was 26.168… sad 😣 ### 5/5 — So convenient. Wish can use in Apple Watch. *2021-11-05* Love it ### 5/5 — Negative number? *2018-12-12* Love this app. One minor thing is that I can't input the negative symbol as the first character, so everything when I want to convert negative numbers I have to do zero minus the number(like 0-5), instead of just minus and the number (like -5). It's not a big issue, but I would appreciate it if you could fix it. ### 5/5 — Great little app! *2018-11-02* Very convenient and useful when traveling overseas. I used it a lot in SE Asia recently. ### 3/5 — Bug report *2018-05-17* 1 m(3)= 1 dou 1 dou=0.01m(3) ### 5/5 — Very good !! *2017-07-12* Is a basic part of my survey tool in the field. For the reports, Im able to submit the data in more than 1 unit ej. Inch and mm . ### 5/5 — 👍 *2014-08-22* Good ## Frequently asked questions about Unitify ### What does Unitify do?
