What's New in tcCalc

3.8

October 1, 2026

Version 3.8 makes features easier to find and the screen easier to read. New • History and a ••• menu (Copy, Paste, How to Use & About) are now always available at the top of the screen. The swipe-up and touch-and-hold shortcuts still work. • Added How to Use, which explains the F / T / S keys, memory, history, and copy and paste. • Each history entry now shows its frame rate and date. Swipe left on an entry to delete it. • When an entry was recorded at a different frame rate, the history shows which rate restoring it will switch to. Improvements • If the clipboard contents can't be pasted, an alert now explains what can be pasted. • Improved contrast, including the operator keys in dark mode. • At accessibility text sizes, touch and hold a key or a button at the top of the screen to see it enlarged. • Improved VoiceOver descriptions for the F / T / S keys and history. • Fixed the top row being cut off at the top of the screen in landscape.

I use this timecode calculator every day

I run a stock footage company and have to calculate durations in 24fps, 18fps and sometimes other frame rates. I’ve found this calculator is a real godsend.

Thank you so much for your kind review! As an independent developer, it means a lot to know that the app has become part of your daily workflow. I’m especially glad it’s helping with calculations across different frame rates. Thank you for using and supporting the app!

Love this but there’s a bad glitch

I’ve been using this app for years and it’s great however in the past 2 months there’s a glitch asking me if it’s ok to cut and paste. This pop up happens before every single calculation and is driving me crazy. I’ve tried to delete it and put it back on my phone a few times to no avail.

Thank you for your review and comments. The paste confirmation screen is displayed due to Apple's privacy protection specifications. Therefore, it cannot be completely hidden. However, the frequent display of the screen could be improved. We plan to fix this in the next version 3.5 to reduce its frequency.

レイアウト戻して

レイアウトが変わってやりずらい、アイコンのような四角いままでいてほしい。オシャレにしなくていい、ミスが無いように使えれば

コメントありがとうございます。これまで一部に古いプログラムを使用していたため、今回新しく更新しました。導入したばかりでご不便をおかけすることもあるかと思いますが、不具合があれば出来る限りすぐに対応いたします。今後ともよろしくお願いいたします。

Been using for years

I’ve been using this app for years and have never had an issue. This latest update, however, has made the calculator completely unusable with my iphone.

Update: App has been fixed. Great again for my needs.

Thank you for your comment and continued support. We identified an issue introduced in version 3.0, which was fixed in version 3.1. We are also continuing to make further improvements and plan to release version 3.2 soon. We truly appreciate you using the app for such a long time.

App UI too big

After app was updated, the UI is too big, half of the calculator can’t be seen. Using an iPhone 14 pro max.

Response from developer

Thank you for your comment and rating. At this time, we were unable to reproduce the display issue in our simulator environment (iPhone 14 Pro Max / iOS 26.2). As a precaution, could you please try deleting the app and reinstalling it? In addition, we are working on improvements related to this issue and plan to release an updated version (v3.2).

FAQ

How does tcCalc handle timecode calculations?

tcCalc allows timecode calculations with the same feel as a regular calculator. You can input timecodes and use standard operators like +, -, and =. For example, the '-' button can calculate the elapsed time between two timecodes.

Can tcCalc convert between timecode and frames?

Yes, tcCalc can easily convert between timecode and frames. Pressing the 'F' button converts the displayed value to frames, and pressing the 'T' button converts it to timecode. This can be done freely during calculations.

What frame rates does tcCalc support?

tcCalc supports a wide range of frame rates including 23.98fps, 24fps, 25fps, 29.97fps, 30fps, 50fps, 59.94fps, and 60fps. It also distinguishes between drop frame (DF) and non-drop frame (NDF) methods for relevant rates.

How does tcCalc manage input and results?

Input values and calculation results are automatically adjusted to be within the range of 0 to 24 hours. You can enter numbers up to 8 digits long. Negative values are displayed as 24 hours minus the corresponding value.

Is tcCalc compatible with other apps?

Yes, tcCalc features copy and paste functionality. You can press and hold the calculation result to copy it and paste it into other applications like notes or the iPhone's standard calculator app.

Does tcCalc have a memory function?

Yes, tcCalc includes a memory function with 'm+', 'm-', and 'mc' buttons, similar to a typical calculator's 'mr' button. Memorized values are displayed in the upper right corner and can be used as input values.

How often is tcCalc updated?

The latest version of tcCalc is 3.5, and it was last updated on April 7, 2026. This indicates a relatively recent update, suggesting ongoing support and potential for future improvements.

What is the price of tcCalc?

tcCalc is a paid application priced at $0.99. It does not feature in-app purchases or advertisements, offering a straightforward purchase for full functionality.
