★★★★★ I had to uninstall and re-install the app and now all data is lost.
★★★★★ I deleted the app without trying it.
★★★★★ Every week there's new bugs: the watch app stopped syncing, the main app calendar automatically shows you the 1st day of the month instead of whatever the current date is.
22 of the 1 and 2 star reviews.
★★★★★ Full screen unskippable ads every time you try to do something, often glitching and replaying nonstop with no way to close.
★★★★★ The last update was extremely glitchy and couldn't save any of my recent progress pictures.
★★★★★ I was really happy with Tray Minder until the recent rapid fire updates, which have left it an unusable, buggy mess.
21 of the 1 and 2 star reviews.
★★★★★ Extremely unhappy that I attempted to cancel the free trial and it somehow did not “stick.” When I received a charge I did not expect I saw they had charged me for the year and even though it was less than 24 hours and…
★★★★★ I am also unable to see if my re-installed app is still linked to my paid subscription
★★★★★ I assume they still make money on ads even if I don't subscribe.
20 of the 1 and 2 star reviews.
★★★★★ Loses a lot of points because of how much the ads get in the way of editing data and how hard it is to exit the ads once the timer is up.
★★★★★ However, the ads go on for minutes and you have to interact with them many many times before a way to close the ad appears.
★★★★★ This used to be a functional app, but it is so riddled with ads now that it has become unusable.
16 of the 1 and 2 star reviews.
★★★★★ The last update was extremely glitchy and couldn't save any of my recent progress pictures.
★★★★★ Update: still not a great app.
★★★★★ After a recent update, almost every time I go to the edit section, I am presented with a full screen ad stopping me from doing the edit and not able to dismiss it for a predetermined amount of time.
11 of the 1 and 2 star reviews.
★★★★★ First of all, they limited the number of pictures you can take, which is a much lower number than most people have aligners during their treatment so I had to delete half of my pictures to add more.
★★★★★ Now the developers got greedy and put intrusive ads everywhere and limited the amount of progress pictures.
★★★★★ Now, if I want to remove ads, I have to pay $5 per month.
7 of the 1 and 2 star reviews.
★★★★★ I don't mind occasionally watching ads for things to be free, but when there is never an option to close the ad at the end, it's useless.
★★★★★ UPDATE: Re: the developer's response: Thanks for not addressing my actual concerns. I know my current “teethies” are not lost—the problem is not being able to take any more. I don't want or need the Apple Watch…
★★★★★ So although the free app works great, the Apple watch software is unfortunately not accurate and inconvenient (although it's supposed to be).
7 of the 1 and 2 star reviews.
★★★★★ Legacy watch support should be available until 2027 but now the app on my watch is saying I need to subscribe.
★★★★★ While No Ads is still working, my Apple Watch support has vanished with their TrayMinder+ service.
★★★★★ I fully support the developer's need to get paid for their work but now we are limited to only 10 (!) photos.
99 of the 4 and 5 star reviews.
★★★★★ I like this app much better than the one from Invisalign. It is more intuitive and easier to use. My favorite feature is the reminder to put my trays back in that keeps reminding me if I miss my goal time, in 5…
★★★★★ I am currently on tray 2 of my aligner journey & this app helps keep me accountable for hitting my 22 hr/day!
★★★★★ I have been using this app consistently since starting my Invisalign journey earlier this year and it has been beyond helpful!
83 of the 4 and 5 star reviews.
★★★★★ it is intuitive and easy to use, and the alarms are critical to help me remember!
★★★★★ It is more intuitive and easier to use.
★★★★★ I find this really easy to use and very straight forward and user friendly.
17 of the 4 and 5 star reviews.
★★★★★ And I only need the free version, although if I had an Apple Watch I might pay more for the extra features.
★★★★★ I used both the free and premium versions and they are both great.
★★★★★ Subscribed to the TrayMinder plus and I love the features. So easy to use and keeps me accountable. My orthodontist was impressed that I was able to increase my wear time from 18 to 22 hours a day since using the…

★★★★★ The user interface is excellent.
★★★★★ The interface is so much better and it has a lot of useful features allowing you to take control of tracking wear and off time.
★★★★★ Good UI and UX, easy to use.
10 of the 4 and 5 star reviews.
★★★★★ This keeps me on track with my goals and monitoring my progress with Clear Aligners. I also like the option to take photos!
★★★★★ Let's say a user typically goes to bed at 4am, or pretty much anytime after 12, it'll be more accurate tracking day to day wear, especially if they had a bad day of not putting in aligners.
★★★★★ Very thoughtful functionalities, everything works great, Apple Watch companion is also a delight to use.

Habe die Bezahlvariante genutzt für meine Behandlung (5 Monate). Am Anfang habe ich nur für das Tracken der Zeit genutzt, was ich am hilfreichsten fand. Da hatte ich noch kein Gefühl wie schnell die Zeit rum ist 😅 Später habe ich immer Fotos hochgeladen um den Fortschritt festzuhalten. Fand ich auch eine super Motivation. Ich habe die App sogar meinem Zahnarzt gezeigt und er war begeistert. 🙂 Tolles Hilfetool, auch kostenlos.
Extremely unhappy that I attempted to cancel the free trial and it somehow did not “stick.” When I received a charge I did not expect I saw they had charged me for the year and even though it was less than 24 hours and I appealed twice apple will not refund. Seems really shady and I am extremely unhappy.
Helps me keep track of my aligner wear time! Also, great and frequent updates. Loses a lot of points because of how much the ads get in the way of editing data and how hard it is to exit the ads once the timer is up. If you don’t want people to use your app for free, don’t offer a free option. Best way to avoid ads is to start and end timer accurately; the app and the ads within them can be annoying for forgetful people like me. I’m only human!
The app itself works OK. However, the ads go on for minutes and you have to interact with them many many times before a way to close the ad appears. Seems like a violation of App Store policies. Very disappointed.
This used to be a functional app, but it is so riddled with ads now that it has become unusable. Full screen unskippable ads every time you try to do something, often glitching and replaying nonstop with no way to close. Deleting
Update: the issue was fixed. After the latest update, the app freezes on the main screen and becomes completely unresponsive.
