HOW SURE ARE WE
Small app: combines its grossing ranks with ratings growth (24 new ratings a month on average since launch). Tested on 418 apps with verified revenue: typically off by about 2.6 times, so the range is wide. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

Wrong or poor results13%

3 of the 1 and 2 star reviews.

★★★★★ The app shows promise, but there are some inaccuracies in the balance calculations when adding payments.
★★★★★ I'm sooo disappointed in what I just purchased through this app. I was hoping by purchasing the strategies for paying off debt that it would show tips, or even show additional payment methods to paying off the debt…

WHAT THEY ASK FOR
  • I do wish it let you select the type for each debt instead of a generic entry. 4★, May 22, 2026
  • It does not offer any ability to add an additional monthly amount overall to see how fast you can get stuff paid off. 4★, Sep 11, 2023
  • Not even sure what the current payoff date represents without the app knowing how much extra you are paying - needs a guide and/or FAQ. 3★, Jun 20, 2023
  • I also wish it showed an overall schedule of payments and balance on each debt. 4★, Dec 30, 2020
  • You should add the ability to put a promotional APR and also the ability to increase payment at a certain time. 3★, Dec 29, 2019
  • I have already paid the amount set up as my minimum, however if I add more before the next month, I cannot add an additional payment made... 3★, Dec 10, 2019

★★★★★May 22, 2026
It’s decent, but limited

I use the app knowing it is in no way an accurate pay-off calculation. The reason why is there is not a way to differentiate between the types of debt. Interest on a credit card accumulates differently than it does on an auto or personal loan. I mainly use it to see how much I am applying to the next debt for pay-off. I do wish it let you select the type for each debt instead of a generic entry.

★★★★★Feb 14, 2026
Disappointing

Wish I had read Coyas review before I spent the money. It tells you strategies for paying off debt but no place to put in your income. Just gives these freeball numbers that are higher than my income. I was looking for a strategy for MY BUDGET. Not for the money that grows on trees. Still haven’t found that seed yet.

★★★★★Dec 31, 2025
Using it

I would like to see that you can make an additional payment other than on the payment due date

★★★★★Sep 25, 2025
Almost perfect

This app would be perfect if you could easily add (+) an extra payment from within a debt-view page. Currently it appears I can only track scheduled payments. Workaround is to edit the toal owed amt

★★★★★Aug 14, 2025
Good for me

Maybe not for everyone but I personally appreciate the simplicity of this app. I just need to see all my debts in one place and monitor/track my progress. THAT’s IT!!! None of the extra nonsense. No extra tabs. No random features I don’t need. No ads. No begging me to upgrade to premium. Etc.

★★★★★Jul 12, 2025
Not helpful

Save yourself the money and look up on Google what the avalanche and snowball method are. All it does it tell you. I was expecting that in addition to organizing my debts, that it would roll a payment into the next once something was paid off, and it definitely did not. Classic bait and switch.
