It would be great to be able to: -add annual lump sums in addition to the monthly contributions, to account for bonuses -solve for the required opening balance ### 4/5 — Great App! *2022-05-10, version 1.3.0* I like this app very much. It’s simple, uncomplicated, and effective. However, I wish I could enter length in months in addition to years. I have the need to figure out the compound interest for 30 months, and I am unable to enter 2.5 years. That would make it a 5 star app from me. Please consider adding that capability. ### 5/5 — Easy to use! *2019-12-28, version 1.2.0* Love it. One suggestion is to be able to name the tabs, instead of simply seeing the total. ### 5/5 — Love it! - One Suggestion... *2019-11-22, version 1.2.0* I like this app a lot! It’s almost perfect. Things I love: - The interphase is clean, esthetically pleasing, and easy to navigate. It’s not oversaturated with useless features and it’s ad-free. I like the option to choose between dark and light mode. - The app opens and responds smoothly. It doesn’t feel glitchy. - It offers great versatility in being able to compound interest in different time intervals (i.e. monthly, quarterly , semi-annually, etc.) - It provides a graph and a breakdown (list) of compounded gain at each interval selected. I like that I can scroll my finger through the graph to see my projected gains for each interval. - I like that I can create multiple tabs with different calculations which stay open even after exiting and relaunching the app. My one suggestion: - The tabs cannot be title-customized and only display the projected total earnings. It would be a nice feature if I could custom-label each tab to keep track of different investments (such as 401k, IRA, ETFs, etc). Overall this is an excellent app and I’m quite happy with it! Keep up the good work! ### 5/5 — Fast *2019-08-15, version 1.1.0* Fast answers to the question about what happens if I can keep my hands off my money. Try just $1000 with no additional investment for 30 years. If your 25 this is your nest egg at 55 ### 5/5 — Great app *2019-08-10, version 1.1.0* Clean, simple and easy to use design! ### 5/5 — Wow... This is awesome *2019-07-18, version 1.0.1* I never ever leave reviews... but this is awesome. ### 5/5 — Great App *2019-07-06, version 1.0.1* I love this app. I wish that the team would allow me to submit feedback for features when it asks if I “Love This App”, instead of a tip. They could do so much! First feature I want is the ability to share my calculation with someone via text, email, WhatsApp, etc. Fairly straight forward sharing functionality. That I would give $0.99 tip for - not gratuity - rather buying a utility :) Great job, could be even better! ### 5/5 — Ortizghghj *2019-05-26, version 1.0.1* Hola ### 5/5 — Almost the perfect app!! *2019-05-09, version 1.0.1* Beautiful UI, clean, and just overall nice to use. However, if the dev could add an option to change the compound rate, I personally would really appreciate it. I use compounding to figure out my daily, weekly, monthly, and annual targets for my trading. This app would solve everything I’ve been looking for if we could just have an option to change the growth rate by daily, weekly, etc. Either way, great app. Love it. Thanks for taking the time to pair beautiful form with very helpful functionality. ## Most critical reviews (10 lowest-rated) ### 1/5 — Withdrawal mode *2026-05-16, version 1.3.1* There’s no function for withdrawals ### 1/5 — App keeps freezing *2024-02-17, version 1.3.0* The app freezes every time I attempt to change the initial amount ### 1/5 — Compound Monthly *2023-06-30, version 1.3.0* Can’t get the app to give me monthly calculations….PLEASE HELP ### 1/5 — Broken App *2023-02-08, version 1.3.0* This app used to work. Now when I click it, and it opens up, the screen is frozen and when I tap the screen the app crashes. This app literally does nothing now. ### 1/5 — iPad version broken *2021-11-14, version 1.2.0* iPhone version works fine but the IPad version is completely broken. It doesn’t register changes to Starting Balance or Return Rate and ends up constantly resetting Starting Balance to zero. Ability to change currency missing It also lacks the ability to change currency and corresponding number formatting and it affects what I’m doing. ### 1/5 — Don’t Work *2021-08-10, version 1.2.0* I just purchased this App and it’s not working. I can’t input any numbers. ### 1/5 — CALCULATIONS ARE WRONG! OFF by 41% *2020-12-07, version 1.2.0* Based on layout I purchased this $1.99 app. NOW I WANT MY $$$ BACK. IT’S CALCULATION is OFF by 41%. ### 1/5 — Haven’t even used it yet and you want a review?! *2020-07-24, version 1.2.0* even used it yet and you want a review?! ### 2/5 — S Q q *2022-03-30, version 1.2.0* You see Iew q. You by weeke wast )@time s sssll ok w as epaulettesthx senescence aw (7 ### 2/5 — So, So *2020-02-11, version 1.2.0* No inflation option, and no negative contribution (deduction) option. These are real life variables. ## Most praised reviews (10 highest-rated) ### 5/5 — ❤️‍🔥💔💵💵😳😳😳💵👆😅😅🥲🤣😅🥲🥲🥲🥲 *2026-05-30, version 1.3.1* Tung tung shaar ### 5/5 — Nicest Savings Calc Out there *2023-05-07, version 1.3.0* The calculator does quick simple calculations but it also looks the best out of many ive tried. The outputs are labeled clearly and displayed in nice cards. One suggestion that would enhance the simplicity and speed of inputting values is a slider to increment/decrement the numbers that way the user does not have have to wait for the keyboard to pop up and erase the old values. Otherwise a great implementation of a calc. ### 5/5 — Good App *2023-03-04, version 1.3.0* Good App. Would like to see a feature to save the financial model with name instead of “A”, “B” etc. ### 5/5 — Very nice and simple *2022-11-28, version 1.3.0* I think it’s nice, but I wish that it would allow you to adjust for how many months you have to retire instead of years. Reasoning? I plan on retiring in December and seven years. So once this December passes I have to reset the years to six. And then it throws everything off. ### 5/5 — Perfect. *2021-08-11, version 1.2.0* Everything you need in a compound calculator, ESPECIALLY the multiple tabs ability. 5 thumbs up! ### 5/5 — Casa eltigre *2021-07-20, version 1.2.0* Casa eltigre ### 5/5 — Beautiful App + Request to developer *2021-02-09, version 1.2.0* Love the simplicity of the app and the overall design. Stands out amongst multiple options in the App Store. While you could use the calculator in your phone this is a significant improvement and clearly quicker to do the same calculation. Request to developer - this appears to be the only way to contact the developer. So here it is. Would like the app to include calculation for savings withdrawal mode. It makes sense in as this is aimed towards calculating investment growth and planning retirement. There are free apps offering this functionality however I prefer to use Compounder. Many thanks for the consideration. ### 5/5 — No nonsense *2020-12-19, version 1.2.0* Exactly what’s needed, nothing more, and no obnoxious advertising. ### 5/5 — Simple and Easy *2020-01-09, version 1.2.0* Love this App. It makes running numbers simple and easy. As things should be. Simplified. Some things I would love to see in the future is being able to calculate a negative interest rate. ### 5/5 — Love it! *2020-01-07, version 1.2.0* Can you add an option to see a second and third graph showing +- an interest rate? For example, you can select a rate right now. So if I select 20% +- 5% the second and third graph would show the 15% and 25% rates as well. This can help show the range. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
