Just what I needed. ### 5/5 — Excellent and useful app *2020-10-21, version 1.2* Thank you! ## Most critical reviews (10 lowest-rated) ### 1/5 — Very confusing. *2026-05-09, version 1.9* Not intuitive. Could not figure out keystrokes to delineate hours, minutes and seconds. Deleted within 5 minutes. ### 1/5 — hour-minute *2023-03-29, version 1.5.2* It keeps calculate my figure into hours/minutes/seconds. And I don't know how to put it back to numbers for math. ### 1/5 — poor time calc *2021-06-19, version 1.5* uhm, I want HOURS and Minutes, NOT DAYS! Stupid inefficient calculator. ### 2/5 — Nice idea, but poor execution *2023-12-07, version 1.8* While it does calculate time, there appears to be zero keyboard support and no way to turn off the calculation results turning to Days instead of remaining as the Hours/Minutes I need. Addtionally, the lack of a Help/User guide just seems like a poor oversight. Maybe in future iterations these opportunities can be addressed. Until then, I will have to find a different solution. ### 3/5 — Why did the change it? *2024-05-16, version 1.9* I use this for work. But the older version was better :( ### 4/5 — Very good time calculator *2026-08-14, version 1.9* I have a need on occasion to calculate times given a start time and one or more event durations in minutes. I tried several time calculators, but this one really is the nicest. I love the way you can specify the units by adding ‘d’, ‘h’, ‘m’, and ’s’ to the number; other calculators assume you want to enter hours, minutes, and seconds, and you need to type the entire set of digits in regardless. This one allows me to enter ‘10h35m + 127m =‘ and I get the correct answer. Very nice. I would love to be able to specify a default unit, so that, for example, if I leave off the unit, the app will assume the default (say, if I just enter ‘102’ it will assume minutes — or hours or seconds, or whatever I specify the default to be). I also note that I’m unable to change any of the settings in the Settings dialog. I will be sending this info and other suggestions to the developer. But, overall, the app does the job better than any of the others I tried. ### 4/5 — Convoluted data entry. *2024-08-26, version 1.9* You should be able to just set a time format and enter values by decimal point (or comma, or colon) without having to delineate the DHMS with every entry. It's a totally uneeded extra step and ruins the calculators ability to be effective for 10-key entry. ### 4/5 — Ok but *2023-06-21, version 1.6* Will do fractions if a second but you need to tap S after = to display them. Tedious data entry. Must specify H, M, S for each digit. I wish we could assume 5M 2 meant 5 minutes and 2 seconds without having to enter the S. Just more jumping around on the keyboard to enter times than necessary. But, good customer service and response from developer. ### 5/5 — No ads, does what it says on the tin *2026-08-16, version 1.9* No ads, does what it says on the tin ### 5/5 — PERFECT *2025-03-07, version 1.9* This is most everything I ever wanted in a calculator, all in one. ## Most praised reviews (8 highest-rated) ### 5/5 — Perfect *2024-12-30, version 1.9* It is very simple and easy to use, and I have found this app to be very helpful when it comes to figuring out times for my recipes. ### 5/5 — Very Handy *2024-10-23, version 1.9* Useful, Free, Ad-Free, and Privacy Respected. What is not to like!!! Thank you ### 5/5 — Simple, fast, works well *2024-02-20, version 1.8* Perfect little app. Does just what you'd expect: lets you tap in times or durations and add/subtract/multiply/divide them. I wanted a quick way to calculate when my renders would be finished - I know what time I started the render, and how many frames my machines have rendered so far. Easy enough to work out on a bit of paper, but this app makes it faster. Thanks Yoshihiro! Feature requests for if you're bored (!): - When you first open the app it automatically inserts the time now, which is ace. it'd be nice to have a "time now" button (and keyboard shortcut) to stick the current time in too - I don't need to use decimals, so a way to switch the numpad "." character to insert a "unit break" would be cool - so you could type 13.02.09 rather than 13h02m09 - And if you want to make a pro version, it'd be great to be able to handle h/m/s/frames, so we could use this for timecodes too. Bit more complicated tho ¯\_(ツ)_/¯ Cheers :) ### 5/5 — So Intutive *2023-06-10* Within 10 seconds of downloading I could start to use it very effectively because it uses natural language notations to do calculations E.g. 2h30m etc.. I had to calculate when I have to start from home to for the airport flight to catch. The quick calculation showed when I have to start E.g 11h10m - 1h30m - 30m - 2h30m = and bang comes the answer. ### 5/5 — Should use a colon : instead of point . *2023-02-15, version 1.5.2* This app does exactly what I needed, simply and cleanly. One minor thing, time is marked with a colon, such as 2 minutes and 40 seconds being written 02:40 ### 5/5 — Great App *2022-11-21, version 1.5.2* I am a Business Supervisor and this app comes in handy when completing schedules and double checking payroll hours. ### 5/5 — OTR Truck Driver. *2022-04-01, version 1.5.2* This calculator is very helpful when calculating my Driving Logs. It’s all about the time and being accurate which is crucial. I would like to access the darken out version. I’m not sure of how to bring the night version up. Any guidance would be appreciated. ### 5/5 — Great Time App *2021-11-13, version 1.5.2* Does just what it is supposed to do. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
