App Update October 14, 2026 v1.3 ### 4Level 1.3: the ring closes when you are recovered After a hard run you are tired, and that is not overload. Version 1.3 makes 4Level tell the two apart. The form state now follows the trend of the last days, and a new recovery timer shows how long each session takes to recover from. Dots fill the gap at the bottom of your level ring, and when the ring closes, you are recovered. A heart beating at your own resting heart rate shows how long is left. 4Level reads resting heart rate, heart rate over the day, HRV and cardio recovery from Apple Health. It analyses your history once and adapts the timer to how you actually recover, with an Apple Watch or another device that writes heart rate to Apple Health. As always, everything is calculated on the device. Version 1.3 is available now in the App Store.

Release notes — newest first - Studio In the works: 4Mail – one mailbox, many addresses October 11, 2026 I’m currently building my new app [4Mail](https://4mail.app.robspace.de), an email app for iPhone, iPad and Mac. What makes it special: 4Mail turns every address and every folder of your mailbox into its own box that works like a separate mailbox – replies go out from the right address, and each box has its own settings. On top of that: to-dos from mail, an agenda with your calendar events, and a morning briefing written by Apple Intelligence on your device. 4Mail works with Gmail, Microsoft accounts and any IMAP account, with no server of its own, no ads and no tracking. The release is planned for around the turn of the year 2026/2027. Gmail is a trademark of Google LLC. - 4RSS v2.5 Five Languages, Feed Icons Without Google October 2026 - Now in English, German, French, Spanish and Italian. - AI summaries are written in your language. - Feed icons load straight from the feed’s own website, no longer via Google. - Studio 4RSS 2.5: Five Languages, Feed Icons Without Google October 5, 2026 **4RSS 2.5** is out, and it now speaks English, German, French, Spanish and Italian.
