Or between two days. Days, weeks, even hours! Would love to be able to have it count just weekdays. Though easy to get there from the count of weeks. ### 4/5 — Please Add Months *2026-02-12* Surprisingly, I use this app quite often. It helps me out when needed. The 1 thing I am requesting is: PLEASE ADD MONTHS TO THE ALTERNATIVE TIME UNITS. Why don’t you have this? ### 3/5 — Updated review, late 2024 *2024-12-24, version 1.1.0* I have happily used the online version of timeanddate.com for many years and it is very powerful. This app was useful a few years ago, though very limited. It hasn’t been updated in several years. ### 3/5 — Meh. Lame one trick pony. *2024-12-12* No option to include end date in calculation. Can't calculate date intervals (add or subtract number off days, weeks or months from start date. Website it's based on is much better, more complete. ### 2/5 — Deleting and finding another date/time calculator *2024-06-09* This app used to work pretty good, and all the functionality was solid. But it seems like different functions just randomly quit working in an unpredictable manner. For example: here lately, the time input function just stopped working. If you select “include time” in the start/end date calculator, the app won’t let you change the time from 00:00. It’s just stuck there. So if I wanted to see how many days it is from one date at 05:00 to another date at 13:00, I’m out of luck. I tried closing the app out and restarting it, restarting my iPhone, and then even deleting and reinstalling the app, and nothing worked to fix this issue. The ability to select a certain time doesn’t work in the to/from date calculator or the add/subtract date calculator. I’ll be finding another date calculator app now. This is especially frustrating because I had purchased the upgraded add free version, and still continued to have this issue. ### 3/5 — Missing an obvious button *2023-08-22* Why wouldn’t you include a button labeled “now”? I downloaded this app because was frustrated others didn’t use 24 hour time, but unlike the wonderful website, I have to manually enter the current time of day. Why make me scroll to “20:43”? ### 2/5 — Missing Too Many Functions *2021-12-02* For context: I use the app creator’s website frequently, and I love the depth of functionality. This is basically the website’s “Time Duration Calculator” page and “Date Calculator” page, minus significant functionality. That is why this app is so disappointing. There is no way to exclude important days, and choose purposeful data sections. For example, you cannot filter for only business days (i.e. no business days or holidays), only weekdays, or exclude holidays. Additionally, the extra choices in settings, which have slider toggles, are completely non-functional. I spent a silly amount of time attempting to click, slide, restart the app, restart my phone, and otherwise engage the other optional choices (with no avail). I paid the $2.99 to remove ads right off the bat, because of how much I love the website. I wish I hadn’t, since the app isn’t usable to me as is. Given the app creators, I hope that those additional functions will eventually be added. I also wish this was a true Time AND Date calculator. I wish you were able to calculate things like total hours between X and Y time (without arbitrarily adding a date), add or subject increments of time, and add/subtract time via an expression, as they have on their website’s “Time Calculator” page. Hopefully in the future. ### 3/5 — Toggle options not responding *2021-09-15* None of the toggle options work in the app's settings. Tried quitting and restarting the app. ### 2/5 — Missing Weekday Only Option *2021-06-04, version 1.1.0* I need to calculate weekdays only just like on your website but the app does not have this option at all. Nice app but complete waste of time if you’re not going to include important features like this. ### 3/5 — Tab button to include loaction wont work. *2021-03-07, version 1.1.0* I have purchased the apps because of very easy ad simple to use but one comment is that the include location doesnt work, the tab button wont work. Hope the developer can help to clarify this issue. ### 4/5 — One more thing *2021-02-11* Would be awesome if this could keep track of multiple dates ### 4/5 — Great app, lean and fast! *2021-01-31, version 1.1.0* I have happily used the online version of timeanddate.com for many years and it is very powerful. This app doesn’t have all that muscle, but it is still excellent! The UI is great, the app is fast, it does exactly what I need it to do and does it well. When the devs expand the feature set some, I’ll add the fifth star. Thank you!! ### 4/5 — Nice app but *2021-01-23* It’s a nice app like you can easily calculate from date to date and add or subtract days, months or years. I also visit your website. But I can’t change my settings, when I am clicking on ‘on’ or ‘off’ button, it is not changing. In previous version (1.0.15), I was able to change the settings. Please fix this issue. ### 3/5 — Keine Anzeige für Kalendermonate *2020-05-23* I hoped for a helper to add up months, like in „how many months have passed from 5/3/2018 to 27/7/2025“. But sadly it goes from weeks to years with no option to get a number for months. ### 4/5 — Time & Date Calculator *2020-04-27* Very simple and useful App. Thanks to the Designers. .....Shrikant ### 4/5 — Klasse *2020-03-30* Einzig beim Rechnen mit Stunden würde ich mir einen „Jetzt-Button“ mit der aktuellen Zeit wünschen. When calculating with hours, I would like to have a „now“ button for the current time. ## Most critical reviews (10 lowest-rated) ### 1/5 — The “time”function no longer works. *2026-04-18, version 1.1.0* This app doesn’t function properly. This is 2026. The app has not been updated since 2020. ### 1/5 — Gelddruck Maschine *2023-07-07* Selbst nach dem Kauf der App, ist eine Anpassung in den Settings nicht möglich. ### 1/5 — Pointless app. *2023-03-07* Why did they even bother making this (cr)ap(p), except as a quick cash-grab to sucker-punch their website users? The app is so poorly designed and dysfunctional it’s borderline criminal. What a colossal waste of time and money for the buyer. Do not, I repeat, do NOT, pay money to remove adds for this app. Better still, don’t waste your time downloading it at all. ### 1/5 — DO NOT BUY *2022-10-11, version 1.1.0* This is not the same as the online version. I love the online features this app is useless and none of the buttons work in settings ### 1/5 — I love to crash *2020-02-09, version 1.0.12* Should be better ### 1/5 — Crashes on date pick *2020-02-03, version 1.0.12* Crashes on date pick once I select done in the upper right hand corner. ### 1/5 — Stürzt ab seit letztem Update *2020-01-05* Sobald man ein Start Datum eingibt, stürzt die App ab. ### 1/5 — Crashes everytime *2019-11-18* This app crashes always **Developer response:** Thank you for your input. It would be useful to know a bit more about just when it is crashing for you? Please get in touch with us at support@timeanddate.com so we can try to recreate your error scenario. ### 1/5 — App crashes *2019-11-10* When I try to calculate the days between two dates the app crashes when I select the start date and select done. It does not crash when I select the end date. I’m only having issues on my iPhone but it works great on my iPad **Developer response:** Thank you for your input. We can not recreate your error scenario. Please get in touch with us at support@timeanddate.com with more details and a screenshot. Are you using locations, etc? ### 1/5 — App Crashing *2019-01-24* Launched the app multiple times, it’s crashing. Earlier the app was good, now it’s pathetic. **Developer response:** Thank you for your input. So the app went from good to pathetic just like that? We suggest you try de-installing and re-installing the app from the App Store. ## Most praised reviews (10 highest-rated) ### 5/5 — To be honest *2025-05-09* It work perfectly ### 5/5 — Exactly as shown *2024-09-25* Does what it says it does. It is perfect. Have been using it for a couple of years. ### 5/5 — Best In Class *2023-02-11* This App is the best for Days Calculations and Add/Subtract Days from the Preset Day ### 5/5 — Thanks a lot 🧨 *2022-09-24* It’s app the super best my medicine days exactly calculate 👌🏻this app download now Buddy 👍⭐️⭐️⭐️⭐️⭐️ ### 5/5 — Unable to add time *2021-11-17* 5 star only applies when I was able to include time in the date-to-date calculation. Recently, this option is now not working. When you tap include time, the option keypad or keyboard does not appear except, - it just hides-unhides. Don’t know what happened, maybe iOS 15.1 update messed it up? ### 5/5 — Nice app *2021-11-11* I used the website a lot at work. I decided to see if they had an app. I was happy to see it existed. While the app does not have everything the website has, it does a great job for what I need. I now use the app rather than the website. There are adds, but they are unobtrusive. I use this app enough I felt the developers deserved the nominal amount they were asking to purchase it. ### 5/5 — Very handy *2021-10-28* I work on contract jobs and have different jobs , this really helps with all my calculations **Developer response:** Thank you for your rating and review. We aim to have equal offerings on both platforms, but it's not an easy task to currently achieve. ### 5/5 — Great Date Calculator *2020-06-05* I love this Calculator Application, I use this to calculate when due for next medication renewal for my parents. It calculates Date/Times/Day/Months/Years. I use this to calculate eg: date + 25 days=?, date-25 days=?, dates+Months=? Etc. it’s fantastic! ### 5/5 — Perfection 💯 *2020-06-03* In the 11 years I’ve owned a dozen or so iPhones—and thousands of apps I’ve tried—this here is THE ONLY APP that has never failed me...not even once. Simply put, it does everything that the developers claim it does and it’s *always* super quick, too! An easy five-star app! ### 5/5 — Love this app! *2020-02-06* What a wonderful app. It has the exact functionality that you’d need for date calculation!
