“The app offers a free trial but I was charged $20 within 3 minutes of accessing it. I submitted a request for refund from Apple.” Quickart Album: Photo Cleaner · ★ 1

“Literally so bad. It is nothing like the ad on Instagram. It literally takes cropped hair and pastes it to your face… and leaves your real hair on… it’s comical, honestly. Deleted the app 3 mins after I downloaded it.” Quickart Album: Photo Cleaner · ★ 1

“Does not select hair color.” Quickart Album: Photo Cleaner · ★ 1

“When I downloaded and opened, it gave me the option to toggle on “free trial”. I turned “free total” on. It made me input my credentials as all apps do when you sign up for “free trials”. It immediately charged my account $19.99. I canceled my “free trial” within 10 minutes of download because the app was bad quality and not what I was looking for. I thought no harm since I was in a “free trial” ha! Give me my money…” Quickart Album: Photo Cleaner · ★ 1

“I have contacted Cladwell support several times over the past few YEARS about this issue and they keep charging me.

“I loved the idea of this app. Indy, after hours of uploading pictures, and at least 2 hours trying to “teach” the app what I needed, I got a lot of “unfortunately we can’t…blah blah.” I don’t need anything special—I’m a librarian. The app doesn’t seem to understand that I need a shirt under an open cardigan!

“I love this app, but it feels like every update makes it worse!! The UI just got updated again and it’s bad, plus everything is misaligned and now it’s even harder to just use the app. The UI is fine as it was. Please just let the people who want to use the old, classic UI keep using it without changing it around!” YPT - Study Group · ★ 2

“Been a customer for years but I cannot justify the outrageous price increase for just sleep tracking. $39 to $57 for nothing new I use is ridiculous. All the best but moving on to other apps or options.” Sleep Cycle - Tracker & Sounds · ★ 1

“I’m new to these app, today is my first day, I can’t give 5 stars because idk if it will work or not, idk if it’s free or not, I don’t know anything, but I have read good stuff about it, I just need help and I hope these works. I will updated later on” No Contact: Breakup Recovery · ★ 3

“I’m going through my first ever breakup right now, and it’s the worst feeling. I really need an app like this, but I can’t afford to pay for it. I really wish there was a free version, I’m so lost in myself right now and really need help like this.” No Contact: Breakup Recovery · ★ 2

“Без подписки вы толком ничего не сможете сделать абсолютно кроме как опрос изначальный” No Contact: Breakup Recovery · ★ 1

“Loved this app to start, for 48 days. Had subscription and all. Seemed promising. Loved the aspect of looking what loot my character had coming back from a battle. Then the bug happened which lost my streaks. Had that fixed but more and more bugs keep happening and updates say they fixed them but they haven’t. I JUST updated the newest one and bug keeps happening. I keep editing a task that was relentless with a spe…” Life Reset: 66 Day Habit · ★ 3

“This is a cool way to track habits. I especially like the hero mode but the problem is it doesn’t save the name you assign to your hero, no cosmetics, items don’t seem to really do anything and at some point the app runs out of visuals for both the items and monsters you fight and just shows you a blank card saying you won. Also the notifications need work. It will often spam you with reminders for habits or tasks y…” Life Reset: 66 Day Habit · ★ 3

“Recently when I begin my day, all my tasks are checked off as done and I don’t get the welcome screen.This started as such a cool app but consistency is lacking and bugs are rampant. Kind of disappointed and makes me less excited to use the app. Thanks” Life Reset: 66 Day Habit · ★ 3

“This app is great and really helps me but they need to have a free version. For example I cannot even get in if I no longer am subscribed - I do not need all the extra stuff but screen control on apps and read a couple of pages on books. Really a let down due to that” Life Reset: 66 Day Habit · ★ 2

“I’ve emailed multiple times about my subscription as well as various requests like asking for a pdf copy of the manual and never once have I received a response and yet I’m charged every week for an app I haven’t used once in the last 6+ months because I can’t figure things out or get any help.

“Don’t like ads” Combyne - your perfect Outfit · ★ 3

“I attempted on several occasions to get the AI to recommend outfit ideas with my photo uploaded. Every single time it came back with an error message that “something went wrong”. It could not tell me what went wrong or if there was anything I had done to cause the problem that I could correct. Quite simply….it doesn’t work.” Fits – Outfit Planner & Closet · ★ 1

“Good afternoon, evening, morning to all you guys who decided to read my review, I don’t mean to particularly come off as a cheapskate but there is no reason for a ONLINE AI STYLIST to be paid. Another thing to consider is false advertising (I could be wrong) as when i opened the app it says something along the ways of “continue for free”. I’m sure people would download this to map-out an outfit with ai, but there is…” Fits – Outfit Planner & Closet · ★ 1

“This app is creepy as hell. It does not feel like a harmless motivation app. It feels like spyware dressed up as affirmations. The notifications were disturbingly specific to things I had been dealing with outside the app, across my phone, in private conversations and emotional situations the app should have had nothing to do with. It kept pushing “divine advice” and self-help quotes that felt targeted to my exact r…” Motivation - Daily quotes · ★ 1

“I can’t even go past the first page of setting up. I click ‘continue’ to allow the app access to my Screen Time and then the screen freezes. It doesn’t even let me swipe out of the app so I have to lock my screen and unlock to get out of the app entirely. I’m disappointed that I can’t even get past step 1.” BePresent: Screen Time Control · ★ 1

“Opal recently updated and completely overhauled their app, rendering it virtually unusable. The UI is unintuitive and the UX is overly complicated. I had customized my settings and preference in a way that worked for me and the update wiped them all out. I’ve been using this app since 2023 and now I don’t even know how it works. This was so unnecessary. And to top it off, the emergency pass is only good for one hour…” Opal: Screen Time Control · ★ 2

“Was a great app when you first installed in around January. Honestly worth the price, it helped with my phone time, loved it. Then the update they did about a month ago screwed with the layout and the program itself. Rules that I had are only intermittently followed, and support is just an AI bot. I’d rather talk to a real person and actually have the massively charged app work. I’ll give it another week to see, but…” Opal: Screen Time Control · ★ 1
