I've started with Simplenote years ago, at the time I was happy but it became clear pretty quickly that it was too basic. But to be fair, it's basic and free. Keep in mind it's unencrypted.
While SimpleNote is completely free to use, it offers a subscription option called Simplenote Sustainer for those who want to support the app. Sustainer costs $19.99 per month or $199.99 per year.
