Great app, enjoying the experience!

I reserve 5 stars for either great customer service or a fantastic concept and execution.
PROS: Leap Second offers users an easy, functional way to document our lives in short form, making it possible to reflect on a month, or year, within a super reasonable time span. Being able to pick either a photo or video is great. The reminder option is great.
CONS: I get that this is intellectual property and the developers should make money from their work! Totally support that. I just think the upgrades could be a little cheaper, and that we don’t have to pay over and over to add one little thing here and there. Not sure I’m thrilled about having paid for several features on different occasions! Meh.

Overall, though, this is a really great lite app. What makes it most special is that it offers me a certain time every day to pause and reflect on my life, and to consider how I want to frame what was truly important that day. It’s got iconic features. Worth it.

Thanks for your thoughtful review! I agree with you that there could be a better pricing structure for the app and I will review this. My inclination is to remove the separate purchases and just have the pro version available (but at a cheaper price).
If you have any comments on what you would think is fair here please let me know at

Awesome, except ONE problem!

I love being able to post multiple videos per day, the calendar is great, and I like that you can extend videos to 5 seconds with the pro version (I think 1 second is too short). This is an awesome app!!

HOWEVER, one thing I really hate about this app is the video trimmer. It’s really difficult to select which specific part of the video you want to trim. Every time I want to choose a clip to trim, I have to watch the whole video, take note of the exact second that I want the clip to be trimmed, restart the video, pause exactly at that second, then press “trim”. I’m not sure if there’s an easier way to do it, but if there is I can’t figure it out?? :(

PLEASE this app would be literal perfection if only the video trimmer were better. My suggestion: let us “scrub” across the video with a selection box containing the 1-5sec clip, and allow us to dynamically preview the selection before committing to trim. Pls I would even pay extra money for this.

ANYWAYS I love this app please make it more perfect I will tell all my friends about it <3

Edit: ALSO I wanted to add - I would like to see some of the added features that are present in the original second a day app. Such as: create different timelines, export specific clips as one video, enter daily mood/notes, etc. I would love these features. The main selling point of your app, however, is the fact that I can post multiple videos in a day!

Thanks for your review and your kind words! The video scrubber have that ability (maybe not super clear) but if you press the small play icon inside the scrubber (not the big one) it will play only what will be trimmed. That way you can move back and forth and only play the part you want.

Thanks for your other suggestions! Multiple timelines are coming soon, so stay tuned!

If you have any other questions or feedback feel free to reach out me at

Good but could be great

I love the idea behind the concept and was impressed at the functionality of this app (I upgraded to Pro), but the UX is still a little rough around the edges. When you select a date to import media, I wish it would just show you if you have any photos or videos in that day without having to tap the photo icon to reveal them. Also, when you’re in the screen to select moments to add to your day, seeing the “select” screen pop up and having to tap “select” every time after you’ve already dragged and dropped it is really annoying (doesn’t it defeat the purpose of dragging and dropping?). Once you drag and drop it would nice if you could scroll through them sideways to X out any you want to remove. There are more things like this that if finessed would really make this app stand out; I already like it more than the original 1SE app!
