I have enjoyed this app for years. However! The ads are getting so frequent and intrusive that I can hardly use it quickly. I had less than 10 seconds after opening the app to read anything or select a date. The only trick I have found is to click on any date quickly and then try and remember the number date that I'm trying to get to and click through at the top... Once I am in full view of the full month the ads go like mad. Years ago it was much more user friendly.

Thank you for staying all these years — and you're right, that ad experience isn't good enough. The new MyDays X fixes exactly this: the MDX Credit Bank lets you watch an ad when it suits YOU, earn credits, skip ads, even unlock themes with them. Try it early: mydaysx.club/beta — I'd love your take. — Christian

Too Many Ads! I used this app since I was in high school. It was simple and to the point and didn't have all the extra stuff like other apps. No subscribing for the extra peeks, just simple and to the point but the ads ruined it and now I have to get those other apps that are too much and confusing and I hate that this app made have to move somewhere else. Please fix, I'm happy to re-download once the issue is fixed cause I really did used to like it.

Ads are out of control!... Without the Ads, this would be a really decent app, but the constant ads make it impossible to use. I get they still need to make some money on "free" apps, but 1+ min long ads EVERY time you open the app and then another just moments later? And another, and another... I try it every now and then, hoping they've resolved this issue, but it looks like I will be deleting it. Disappointing...
