Not working
App is not working fix it
Doesn’t work anymore
All pip calculations wrong
Terrible
So plane, lack of options and no Calculations for CFD's Index what a shame
Didn’t work on weekends.
Just didn’t understand why the calculator didn’t work on weekends. The calculation won’t change because of weekends. I want to plan everything before market open for the week but it just didn’t work.
Can’t use during market close?
First of all, as I’m writing this review the market is very well moving and it’s already Monday EST. 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… the fact that you’re paying for this is ridiculous and makes me want to cancel my subscription.
Not accurate
Market is already open but it still says wait until the market is open 😭 i live in the US and market opens on a Sunday for us. Even tried it on Monday 12AM but it still says the market is not open yet lol
Out of reach
It really pains me so much that Stinu isn’t available in Ghana. I need this app so badly
No Thanks
Save your money.
New Layout
Do not like the new layout, you’ve made it harder to read!
Bunk Update
New update wont let me calculate on SUNDAY because “the market is closed”. It’s open. And besides that, I PAID FOR THIS. What if I wanted to backtest? I should be able to use software that I OWN whenever I want. Loved it prior. Unsubscribing.
Not free
Says it’s free, but then you’re hit with a paywall. No thanks.
Why pay
You can easily use a calculator on myFXbook for free. If this developer was smart he’d open up the app for free and run ads for bank on the back end. Too many free resources out there to be paying someone to use a calculator. This app better come with a course and a profitable signal telegram group or I’m out.
Lot size calculators are free online
You shouldve stuck to your ad revenue nobody is paying for this bullshet
Doesn’t work
Please update your app. It keeps saying my input is invalid when it’s correct and I’ve done it numerous times with different pairs at different times with the same error.
Trash
Was cool until you had to pay for it. Now fxcalculator is the move. Sorry
No crypto, no subscriber!!
Include crypto if you want me to PAY for this. Maybe one day someone will get the bright idea to get rid of a subscription just like someone had the bright idea to have a subscription. Anyway, I’ll be using a free and more efficient calculator.
Should Have Stayed Free
Wonderful App... Not Paying For Something That I Can Use On “Myfxbook” For Free. Y’all Were Cool Because Yall Had An App, That Was Easily Accessible
What to do
I would like to cancel subscription, and there isn’t an option to cancel.
Great app just not free anymore
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 👎

🗑
should of stayed free 🤷🏾♂️
Not longer accessible unless you PAY
No longer free to use . App is a waste of space now
🚨Myfxbook has it free
Are u guys really serious ? All of of a sudden you wanna charge $20 for fx calculator ? 😂😂😂
No warning and now locked out!
I 1st downloaded the app with excitement and found it a pleasure to use. Has been using it nicely for awhile until just recently when I launched the app.., a message prompted me to pay $14.99 per year with a 7-days trial period?!! WHY the sudden change of events without informing or warning? 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 😡. The very least is to keep the early adopters in place (grandfathered) without refusing access, right... You’ve just lost a satisfied customer who’s now choosing whether further referrals is a gd idea or not. Keep improving your customer service and understanding “GOODWILL” gestures as that’s sorely lacking. My $0.02 worth!
Scam
This app only works now with pairs that are USD. Please fix. When it was free I could calculate with pair. Now an error comes up when I am calculating any pair not using USD.
stupid paywall
Of course they add a paywall 😐 yea 1 stari’m never taking it off.
nope its not free anymore!'
dont download its not free anymore lol,, this is a joke!! theres plenty of app online to calculate this position size lol..
Stop the paywall
Honestly guys, I know COVID hit us all. But this ain’t the way to introduce a premium to your users. Add new features, give incentive, and if it’s free don’t just suddenly make it 15 that’s nuts lol bueno, hope you guys bring it down this is def overvalued
unnecessary
I was satisfied with the application until they started charging money for something I could create in Excel.
I used to use it!
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 this app. Anyways thank you for your service.
Destroyed your impression
There are free position size calculators out there this is not how you monetize an app. U just digged your grave.
Now paywalled after update
Was a great app for calculating position sizes and easy to use. Now after the update can’t use it until you pay $15 for an annual subscription?? Sorry nope. Maybe if this was a one time payment or a much smaller subscription rate <$3 would consider. Thanks now going back to Myfxbook to calculate.
Don’t buy!!!!!!!!
Don’t pay for this and just go find a free one.
Charging Now???
App developers got greedy for calculating lot sizes smh. Would have been nice for some sort of heads up on charging. I’ll move on like I’m sure ALOT of other people will.
15$ FOR A CALCULATOR 😂😂😂
Owners got greedy. Use Baby pips or myfxbook Calculators and bookmark them to your Home Screen. Thank me later
La hicieron de pago
Era muy buena actualización pero la hicieron de pago y no es tan buena para pagar por ella.
I’m paying for the App to work....
And yet it’s not working. It’s a hugely useful app and my colleagues and I all use it but what good is paying $15 if the app won’t even open?
Used to be free
Charging I’m going to use another app haha 🤪 bye bye Stinu
After not updating the app with its numerous bugs they come out of the blue with a pay wall.
Ive been using this app for a couple months because its the first I downloaded, but it has alot of bugs and doesn't work at times. today i go to use the app and im stopped by a paywall saying they are now charging $15 to use the app. this is not cool. I should atleast be grandfathered in. the app isnt even flawless enough to charge people. most money hungry move.
This app totally switched up on its customers
Was totally free, have been using for 6 months plus. I’ve not used it in a couple days and now all the sudden I’m totally blocked from the app unless I subscribe and pay a fee. Not even an intro offer for this who have been supporting for a while. Sad, because I’d have probably paid 🤷🏽♀️ you shouldn’t treat those who support you that way. The app doesn’t even have calculations for everything you can trade in the market.
Worked great...until the subscription...
Now that I’ve paid the 15 bucks for the new subscription, it won’t work! With no one to call or find our why.
Now we have to pay? 😂
Lol I’ve been using this app for about a year back when it was free and now all of a sudden we have to pay for it. That’s ok I’ll jus find another free platform because paying for an app as simple as this one..... 😂😂😂PLEASE. Good while it lasted though.✌🏾
Help
Is this app free? I have paid and others haven’t. Even with paying i can’t get it to work. Please help
If I could give it 0 stars I would
Everything was great until the app developers got greedy and decided to charge a monthly subscription for a CALCULATOR.. there are other free forex risk calculators out there, don’t waste your money with this app
App
It’s making me pay for a subscription while others use it freely.
Now you have to pay $15 for this??
Wow I loved the app but it auto updated when on settings i have it off. This app was good until this happened smh ... greed.
This app does not work.
I downloaded the app this morning and paid the annual fee. But the app is still on the the main page for me too pay again. It has been over twelve hours. If it doesn't work by tomorrow morning I'm asking for a refund. It seems I have to give it at least one star to post this msg.
Why subscriptions??
Great app but now you have to pay to use it??? That’s an easy deal breaker.
App not allowing me in
I paid my subscription and it’s not allowing me in the app. It was working just fine before the update.
Can I get a refund?
Purchased 1 year subscription and the app still showing error and not letting me use it
Forced subscription and error message
I recently downloaded this app based off of recommendations from my reading group. Initially the app was great. After my 4 time using the app it forces me to subscribe. After subscribing and paying $14.99, it gives me an error message. Needless to say I cancelled the subscription and told my trading group. Lost business from a lot of people.
