MathTeacher brings much-needed upgrades to the native Calculator app

One of the native apps in iOS that doesn’t get the attention it deserves is the Calculator app. While you could download a more robust third-party alternative from the App Store, the fact remains that the native experience is abysmal at best. For that reason, we’re excited to show you a new free jailbreak tweak called MathTeacher by iOS developer Gabriele Filipponi.

As depicted in the screenshot examples above, MathTeacher incorporates several upgrades into iOS’ native Calculator app, making it a significantly more functional math-solving platform than it would have been out of the box.

This tweak improves the timestamps in your iPhone’s call log history

The Recents tab found in the iPhone’s native Phone app is meant to display a running history of your incoming and outgoing phone call activity, making it easier for you to call someone back or reference a phone number if you ever needed to. Sadly, the timestamps for older phone calls tend to become less descriptive over time, showing only the date and not the timeframe.

Thankfully, a new free jailbreak tweak called ExactTimePhone by iOS developer gilshahar7 can fix this problem. As shown in the before and after screenshot examples above, this tweak makes even your oldest phone history items show a timestamp in addition to the date that it transpired.
