- [R2] Battery Life Health Doctor Pro Battery Life: Great use it everyday.
- [R14] Battery Life Health Doctor Pro helps to obtain battery life: this app not only shows you your current battery life. it also has information on how to minimize battery usage. simple to use. just download. i have been using the app for many years.
- [R65] Death Clock Life changing!: I was diagnosed with Parkinson’s Disease. This app addressed vitamin deficiencies and suggestions that have improved my life! I am so grateful! Thank you!
- [R68] Death Clock So far I find it useful: So far I am enjoying the app. There was a feature that recently disappeared tho. The ability to se a series of daily activities that were suggested and that could be logged. I found this feature useful since it moves into current real time vs just bloodwork. I think this app has a lot of potential and promise. I hope to see it grow and develop. I’m at least on board for a
- [R19] Battery Life Health Doctor Pro Advertising: It’s not the app, it’s me. If you advertise purchasing more than three times in the first minute I’m going to delete the app and never use it again. It’s just way too pushy and annoying to put up with.
- [R22] Battery Life Health Doctor Pro Terrible do not get it: Only have the device for a little bit and all it does is give you these worthless tips which anyone can easily tell me and it won’t even let me do the calibration so now I can’t find out the reason why my phone is dying so much
- [R64] Death Clock Doesn't work: One of the stupidest apps I’ve come across on the Apple Store. tried to create an account several times and it wouldn’t work.
- [R90] Death Clock Bad UI Design: The app literally blocks its own “Continue” button with the number keypad and there’s no obvious way to dismiss it. I had to fight the UI just to enter my age. If the goal is to calculate my lifespan, this experience alone is probably shaving years off it. Fix basic navigation, this shouldn’t be an issue in a finished app.
- [R6] Battery Life Health Doctor Pro Don’t buy the Premium: It’s literally worse than the free version. Buggy, the wallpaper feature doesn’t transfer seamlessly into the app platform. The free version is alright for a battery app.
- [R10] Battery Life Health Doctor Pro Give me to access your phone or iPad, fake reviews..: Just the way to get money out of you for junk app and access to your phone or iPad I would not recommend it to anybody.
- [R66] Death Clock Must pay $30-$150 to review results: I work on apps and am sympathetic to the plight of devs needing to monetize. But to proceed with onboarding you hand to create an account + give a lot of sensitive data + then met with a paywall for an annual sub. It hasn’t proven the app’s worth yet & what is offered outside of a death date. Also doesn’t sit right with me that it takes you to Stripe and operat
- [R80] Death Clock Cant cancel subscription: im stuck on the questions it wont go foward after the questions and it wont let me cancel the subscription!
- [R25] Battery Life Health Doctor Pro Worthless: What happened to good utility apps that didn’t require a subscription?
- [R67] Death Clock 299 per year: sucks information and charge $25 a month for real evaluation which you wouldn’t know if there is any accuracy in it or value in it after you already paid and disclosed personal information
- [R116] Death Clock SCAM: I did the trail version and was charged $99 well after the trial date and I even confirmed it was cancelled the same day bc I found the app to be redundant and inaccurate despite me doing everything right and cancelling my bank flagged a transaction for the exact price of the yearly subscription on my debit card. Luckily it was blocked before it went through, but beware of this app
- [R43] Battery Life Health Doctor Pro No help: This app just wants money. I received zero help regarding my battery and it’s calibration and there is zero explanation as to what $20 a year would provide me easy delete for me.
- [R81] Death Clock THEY MAKE IT REALLY HARD TO CANCEL SUBSCRIPTION: I gave this app 5 stars so everyone could see. Just before they took $99 away from my account, I tried looking EVERYWHERE to find a button that would cancel the subscription, only to see that I had to email them. I emailed, and left a voicemail when they wouldn’t respond. Mind you, I emailed them 3 months ago and still have not received any respons
- [R102] Death Clock Extremely hard to cancel: It’s not showing up anywhere in my settings not even in my subscriptions every time I try to go in the app to cancel it kicks me out out of the app I saw another review on here that had the exact same problem I don’t know what to do I don’t wanna make any purchase I’m so mad right now
- [R118] Death Clock Charged 99.99 after cancelling and deleting acccount: I clicked “delete my account” and uninstalled but then they charged me 99.99 days later. I’m guessing my personal information is also still on their servers. Emailed them for refund and I will get it, promise u, but can’t get wasted time back
- [R1] Battery Life Health Doctor Pro Ooops: Didn’t mean to purchase a subscription. Want a refund. Otherwise nice
- [R69] Death Clock Annual Subscription required: No monthly subscription
