Subscription My A***

I used to own this app and it was great… and FREE! Now they charge a monthly subscription. No thanks!!

Response from developer

It’s a yearly subscription for the very reasonable price of £5.99 - and the app was never entirely free, there were always optional in-app purchases, which naturally still work for anyone who actually purchased them when they were available.

Läuft wieder

Update: Inzwischen hatte ich Kontakt mit dem Hersteller. Irgendwie hat die App bei mir den alten In-App-Kauf vergessen. Nun läuft die App aber wie gewohnt.

Alte Rezension: Seit dem Update kann ich nur noch irgendwelche Icons auswählen oder den Timer verändern. Alles andere für nur zum „Plus“-Kauf. Ja, der Entwickler soll für seine Arbeit entlohnt werden. Aber ich habe diese App damals gekauft und inzwischen ist es nicht mehr die App die ich bezahlt haben. Sehr schade.

Response from developer

Alle Funktionen der ersten Versionen sind immer noch enthalten in der App, und sollten für frühere Käufer natürlich auch entsperrt sein. Wenn Sie mir eine Email an dozzzer@voidstern.net schicken kann ich Ihnen weiterhelfen, sollte dabei etwas schief gegangen sein.

Most functional sleep app I've found to actually hellp

Great work on this. I love the selection of soundscapes without any marketing gimmicks. For a sleep app, I think investing in the actual soundtracks and to develop functionality around the music is what it's all about when it comes to an app to help you sleep and relax.

If there could be a way to create certain playlists and/or group together existing soundscapes, so for example you don't have "Random" set for the night but something like "Water sounds" tor instance, this would really make a big difference, at least to me.

Kleiner Helfer

Es wirkt wirkt unspektakulär, Musik so lang schrittweise leiser zu machen, bis man eingeschlafen ist und sie dann abzustellen. Dennoch ist es genial. Ich nutze die App dafür seit Jahren und bin sehr zufrieden.
(Einen Stern Abzug nur, weil mich die häufigen Verweise auf den kostenpflichtigen Plus-Service etwas stören. Die Grundfunktion ist tadellos)

Response from developer

Bitte über Einstellungen > Email Support bei mir melden, dann entsperre ich die Funktion. Für frühere Käufer sollte sie selbstverständlich verfügbar bleiben. Es bleibt automatisch permanent entsperrt für jeden der in den letzten Jahren In-App etwas gekauft hat, nur für die handvoll Nutzer, die die App selbst vorher gekauft haben, funktioniert es leider nicht immer automatisch.

Can’t use it with my own music?

I don’t mind ads and I don’t mind paying for extra features but the whole point of this app was to use my music to fall asleep and that is now behind a paywall? Not a fan.

Response from developer

I know the custom music is the primary feature of the app, and I would have preferred to keep it free, but after almost year, I can still count the active subscriptions on my two hands. If this doesn’t lead to at least some more subscriptions, I’ll probably just discontinue the app.
