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.

WHAT THEY COMPLAIN ABOUT · SHARE OF BAD REVIEWS
Price and subscription40%

28 of the 1 and 2 star reviews.

★★★★★ The app doesn't let you calculate because it thinks the market is closed which for starters, seems pretty stupid not to be able to use even if the market is closed because at the end of the day it's just a calculator……
★★★★★ Every time I try to calculate price it gives me an error saying “the request for market price has failed.
★★★★★ Says it's free, but then you're hit with a paywall.

★★★★★ New update wont let me calculate on SUNDAY because “the market is closed”.
★★★★★ Every time I try to calculate price it gives me an error saying “the request for market price has failed. Please check input and try again.” Just trying to calculate how much is 3% of $100,000 is on GBP/JPY, only pair…
★★★★★ I used to use stinu app, in the last update they bring a subscription, thats is a no brain for me, usually I buy or subscribe to apps that I use or think it worth it but pay, I think this time is a little expensive…
Limits, credits, locked features10%

7 of the 1 and 2 star reviews.

★★★★★ What idiot thought it would be a good idea to limit your use of a paid app to "market hours" that are not even correct.
★★★★★ I've been using this app for soooo long to calculate my risk per trade and all Of the sudden one day I'm surprised that I have to pay now sorry but there are other apps out that can do it for free sorry not sorry 👎
★★★★★ I've already accessed your app as one of your early adopters and users while have been referring other trader friends to use your app too and to be slapped with this locked out action is uncalled for 😡.
Lost data, sync, backup6%

4 of the 1 and 2 star reviews.

★★★★★ Other than that it works great just be prepared to lose out on trades occasionally due to this design flaw.
★★★★★ You've just lost a satisfied customer who's now choosing whether further referrals is a gd idea or not.

Wrong or poor results3%

2 of the 1 and 2 star reviews.

★★★★★ All pip calculations wrong

No customer support3%

2 of the 1 and 2 star reviews.

★★★★★ Keep improving your customer service and understanding “GOODWILL” gestures as that's sorely lacking.
★★★★★ Sad, because I'd have probably paid 🤷🏽‍♀️ you shouldn't treat those who support you that way.
