FM Synthesizer Customer Insights

1. This is called greed, not feeding your family.Paywall mess - This app has barely anything to offer in terms of synthesis, locking the presets I can understand but preventing any alteration to the sound without paying for it? That's hardly fair.

2. I reckon they should fix that but honestly great app$12.99 Subscription is the first thing you see when you load up the application, you're missing 90% of the described features without it.Immediately asks you to subscribe and hides the "no thanks" button.

3. That's what is called "dark UI" and it's evil.the moment i pressed a key...AD. i try arpeggios but they are so late they dont even register.

4. Horrible, Google needs to flag and remove the developer completely from app store.Ummmmm..... Not very great.

5. Stay home, stay safe.Very good app but whenever I go on the app and press the first key it gives me an add and it's the same add of the same app.

6. EDIT: I think that we should probably not use this because it has a ad when you click the game on.Awful. There are way better free synths without a monthly vig.

7. bad...dont know if you even tested this.Here's what it is why would anybody put their card information in just to receive a 3-day trial.

8. Your better off offering this app as a paid experience only and not offer a free version at all.

9. To be frank this is terrible, keys are too big, and the paywall is awful.

10. Just give basic functionality and when someone try to use a feature in the full app give them a reminder.

11. Not only that but it's a subscription not a one time purchase.
