When you need to remind yourself quickly to do something, Quickio is your answer. Calendar, Reminders, and Emails, whatever works for you. The quicker you close our app, the happier we are. Quickio works with the Apple Calendar, Reminders, and Mail apps already on your device. There are no new accounts to create and no new system to learn. Type it, send it, done. CALENDAR & REMINDERS • Add an event or reminder in seconds • Choose which calendar or Reminders list to use • Set a default event length • Repeat daily, weekly, monthly, yearly, on weekdays, or on weekends • Get alerted at the event time or up to a week before, or use a double alert so you're reminded early and again when it's time EMAIL • Send a quick note to yourself or anyone on your saved list • Pick a default recipient so sending takes one tap • Add attachments • Optional subject prefix, signature, and message-in-subject, great for inbox rules and filters MAKE IT YOURS • Open straight to the tab you use most • Light, dark, or automatic theme • Supports Dynamic Type for larger, easier-to-read text • Your settings and stats sync through iCloud, so they follow you to a new phone or a reinstall • Helpful tips to get you started PRIVATE BY DESIGN Quickio passes your events, reminders, and emails to Apple's own apps and stays out of the way. Their contents are never sent anywhere else. Your settings and stats are kept in your own iCloud account, so only you can see them. And if you ever do stick around a little longer… there might be a potato or two hiding somewhere, including the infamous Potato King and his daughter Princess Potato.

Verdict
The clearest difference is in-app purchases: Quickio at none against iSub Player's 1. Quickio also leads on ads (none vs shown). iSub Player's advantage is update cadence (fortnightly vs every 4 months) and device support (3 vs 1). On price there is nothing between them.
