Es erscheint eine Fehlermeldung und die Ansicht ist total verschoben. Danach muss die App neu gestartet werden. Diverse Bug Reports wurden schon gesendet, aber nichts passiert - schade ### 2/5 — Android to iPhone can’t login *2026-08-06, version 3.312* I messaged developer. No response. Switched from android to iPhone and I can’t login via iPhone to get my account details switched over. Long time user probably back before a password was required. Help! Will try email again… ### 2/5 — Used to be awesome *2026-08-05, version 3.312* I have been using this app since March 2011. For years it was fantastic. The options and tracking it offers are still adequate, but as of late the ads are ridiculous!!! An ad pops up literally within 3 seconds, and every 5 seconds after that. Just stop. Ads every 5 seconds won’t make me subscribe. It will make me move to a different app. If you’re new and looking for a cycle app, shop around unless you’re willing to pay for ad free. ### 3/5 — Ads heavy *2026-07-31, version 3.312* I have had this app for over ten years. In the few its gotten so ad heavy its almost not worth it for how basic it is. ### 2/5 — Ads *2026-07-30, version 3.312* Every time I log a day or try to look at my cycle there is an ad. Cannot interact without an ad with every click. So frustrating, if I want to check my last cycle at the doctor’s office and I have to wait for the ad to finish. ### 5/5 — Consistent user *2026-07-27, version 3.312* I’ve been using this app since ‘18, predictions are accurate, easy to use and understand. The ovulation predictions have been very helpful and pregnancy prevention proof, so thanks for that!! 🤘🏼 Through out the years I’ve chosen to disable the ads here and there which is no big deal. I know money can be tight at times but I wouldn’t complain about $1.07 tax included monthly subscription. ### 2/5 — Too many ads *2026-07-26, version 3.312* You can’t even look at your chart for 2 seconds without ads popping up . This app has become terrible. The only good thing is that it accurately predicts my next period ### 2/5 — So many ads!!! *2026-07-16, version 3.312* Can barely use the app with out the ad starting right away. When it’s done it has another one immediately. ### 1/5 — Very Disappointing *2026-07-10, version 3.312* The app feels too basic and lacks the features needed for a good tracking experience. ### 2/5 — Hardly usable *2026-06-25, version 3.312* I’ve had this app for years, but recently I’ve avoided using it because there are just so many ads. You click one thing and you watch an ad. Click the next thing, watch an ad. It’s completely ridiculous, and I’ll be uninstalling. Which sucks because my cycles are so strange and this app did a decent job predicting still. ## Frequently asked questions about MyDays X ### What does MyDays X do?
