### **--- "It’s great when it works"
It’s a great emulator with a lot of nice features and touches.  The skins are great, and it’s really easy to set up.  The haptic feedback and responsiveness of the input are really nice.  

But for the last year or so, I’ve been having a problem where it just freezes and becomes unresponsive. It usually happens when I switch to another app and back. If I reset the CPU, it will sometimes come back, but usually it doesn’t.  Other times, the input will slow to a crawl, only accepting inputs every 2 seconds. The input will get buffered and will enter automatically at this really slow rate.  While it functions, it’s not usable. 

I really love this app, but it’s just become unusable. I’ve had to bring my real HP48 out of storage, but it’s hard having lost the portability and availability of having my HP everywhere I go.

### *---- "Needs Updating"
I loved this app, but it is not maintained and does not function under latest iOS.
-- SBK Resident, 2026-01-10

### *---- "Buggy"
This thing crashes all the time. Don’t Panic
-- Apple is lame no nickname, 2025-11-26

### *---- "Unusable now with latest iOS 18 updates"
Used to be great.  Now constantly turns off about every 3-4 seconds.  Totally unusable.
-- BobTuttle1965, 2025-04-28

### *---- "Bad"
EDIT does not work on my i16 phone.  Did work on my i12.  Almost useless as is for me
-- DEJ1943DEJ, 2025-02-21

### ***** "amazing hp 48 emulator"
my real calculator has developed lcd rot so having this app available has been great. please keep up the great work.
-- Ah Bl, 2023-06-13

### *---- "Froze almost immediately"
When I first opened the app it asked if I wanted to recover memory.  The yes/no buttons are unresponsive
-- casque-lift-super-perfuse, 2023-04-11

### ***** "great app ... but a bug with bottom row of keys"
Perfect - preformed very well until i had to delete and reload.  the bottom keys {0, . , spc, +} are now very flaky.  verified it’s not my screen...  any ideas?  i won’t “upgrade” the iOS on my ‘20SE because i don’t feel like allowing apple to purposely degrade my battery.
-- GregWoodward, 2023-02-20

### *---- "Doesn’t work anymore"
Doesn’t work anymore
-- flythatway, 2022-12-11

### *---- "Buggy"
I loved the original calculator. I love a version of the calculator on Android. I hate this one. I have to tab the buttons several times before it does the action. I have tried on 4 different iOS devices and the behavior is exactly the same. That makes it useless. Nice try, though.
