Smh. I left it alone thinking developers would fix it but its been a while now with no fix smh. ### 5/5 — Resolved *2024-12-04, version 2.0* Hello and first let me say thank you for one of the best apps I’ve ever used. This issue I was having was fixed by changing the text size on my phone. By reducing the text size I was able to see and scroll through the table of amounts by year. If you are not able to see the table reduce your text size and that may work for you. Thank you. ### 5/5 — Also having issues *2024-11-29* Hello and first let me say thank you for one of the best apps I’ve ever used. I am also having issues with the apps after the latest upgrade. I’m on an iPhone 8 and since the upgrade I am not able to see the amount by year. In the old version of the app if duration was 15 years you could see a result for each year with the amount. In the new version I can only see the amount in the last year. It would be nice to see each year again. Seems like I am not the only one with this issue. Again thank you for making a great app. If you could fix or describe how to see a list of all years that would be great. ### 5/5 — New update *2024-11-10, version 2.0* Loved this app for years. Glad you added ads to monetize it (you deserve it). However I cannot click off of monthly to quarterly, yearly, or weeky! Also if possible in a future update, under the withdrawal, to add a percentage option ### 5/5 — Love the app but the update has made it unusable *2024-11-08, version 2.0* Since the update I can’t select the compound frequency. It’s stuck on monthly. I have no use for any but yearly. I’ll hold onto it for a while more but I’ll have to delete if it doesn’t get fixed. Edit: developer contacted me in response to this. In the meantime I discovered that if I long press the compound frequency I can get it to switch but a light tap doesn’t work like it does for the rest of the interface. ### 5/5 — Update *2024-11-06, version 2.0* Experiencing the same issue that another user commented below. I have thoroughly enjoyed this app, but there has been a new update and now I cannot change frequency of compounding. Annoying Ad running across the top of the screen, as well. I know you need to get your revenue, but at least keep it functional. ### 5/5 — New Release Broke App *2024-11-04, version 2.0* I’ve used this app for years, and love it, but the new release broke it. quarterly button does not work, the sheet showing growth by year is one line long, can’t see the other rows unless scrolling to see one row at a time. Everything looks zoomed, so can’t see much on one screen. Can’t toggle to the sheet view. I’m using an iPhone 8. I deleted and reloaded, but that didn’t fix. I hope this new release gets fixed. I’m giving 5-stars because of past performance, but current performance can’t be rated because it’s broken. ### 3/5 — Options *2024-10-04, version 1.5* Not enough options to figure different cats of interest but you guys did good on for what you did thanks ### 3/5 — Needs Update *2024-06-30, version 1.5* It doesn’t scroll all the way to top ### 3/5 — periodic addition needs options *2024-06-14, version 1.5* works exactly as described. Quick and to the point. I do wish the “Periodic Additions” could be adjust in the same way the “Compound Frequency” can be. As of now the “Periodic Additions” just match whatever you set “Compound Frequency” to. I would like to be be able to easily calculate yearly compound interest on an amount that I am making weekly/monthly additions to. As of now I have to do some extra calculations to get the proper number. It would not be difficult to add these changes as this app is essentially just a couple inputs ran through a formula and spit back out. Just need to add another input for Periodic Additions. ### 5/5 — This app is the best one out. *2024-02-24, version 1.5* So easy to use. I invest in stocks and i used to use a free investment calculator online. I had to go to the site and still punch in the numbers. This is so much easier to use. I love everything about it. Right to the point. ## Most critical reviews (10 lowest-rated) ### 1/5 — Update is absolutely terrible *2025-01-09, version 2.0* What have you done with your app. It’s glitchy and not user friendly anymore. It’s went from me using it all the time to deleting it. SAD ### 1/5 — New version not working very well on my iPhone. *2024-11-27, version 2.0* Used the old version very frequently, it was simple and easy to use. I’m approaching retirement so used it to estimate my potential pension growth. Mark In Yorkshire. ### 1/5 — Ruined *2024-11-24, version 2.0* Since the most recent update this great app doesn’t work on iOS ### 1/5 — Was great …. *2024-11-21, version 2.0* It was great since the last update ### 1/5 — New Update Crashes *2024-11-07, version 2.0* Just opened App you could see it has just been updated. Unable to change compound frequency and App will freeze up. Please fix! ### 1/5 — New Update Crashes *2024-11-01* Just opened App you could see it has just been updated. Unable to change compound frequency and App will freeze up. Please fix! **Developer response:** Hello, I'm sorry you've encountered this issue. According to the recent analytics for the update, there has not been many instances of the app crashing. So I am not sure what is causing this problem for you. I would recommend deleting the app the re-downloading again. Please let me know if this fixes the problem. Thanks! ### 1/5 — Not enough options *2023-05-06, version 1.5* This app only asks for annual return rate and ask for compound frequency. If you choose monthly it will still only calculate annual. Need to be able to calculate monthly rate and give correct numbers after a year. ### 1/5 — App removal *2021-02-02, version 1.5* App cannot be removed from iOS 14.4 ### 1/5 — Garbage *2020-12-27, version 1.5* A calculator that is always wrong ### 1/5 — Crashes *2020-09-25, version 1.5* It crashes after like 2 min ## Most praised reviews (10 highest-rated) ### 5/5 — Solid app, I’ll pay for no ads *2026-08-27, version 2.0* I’ve had this app for years and I love the simplicity of it. That said, I was trying to show someone some quick math and a Temu ad came on that was not ideal. I’d pay to get ads disabled.
