### 1/5 — Stopped working, web site down

*2026-09-16*

This app worked very well for the past 18 months. Then, as of a few days ago, it stopped tracking NYC visits. Their web site is also down and emails to support bounce back. They may have gone out of business. Do not buy this app!

### 2/5 — Used to be great

*2026-08-31*

Downloaded this App in November 2025. Worked fantastic until the last week of August 2026. Then they made a huge App Update and now it’s lousy. Very very buggy, and trying to be too complex. Suggest someone spend their money elsewhere if you need tracking APP.

### 1/5 — Latest Update Broke All Tracking

*2026-08-29*

The developer’s most recent update introduced numerous critical failures including tracking days calculation math being clearly erroneous. Support link in the app no longer functions. App is unusable until this and other problems have been fixed. Previously solid.

### 1/5 — App is broken

*2026-08-28*

After the last update the app is broken.

### 1/5 — Developer stopped supporting

*2026-05-13*

The developer of this app stopped supporting the app and has disappeared locking all my data with it. This is not a dependable tool!

### 1/5 — Won’t allow payment

*2026-05-13*

I want to pay for and use this app, but it has been rejecting payment for a month. Uninstalling.

### 1/5 — Couldn’t extend Pro version

*2026-04-20*

I paid for pro for one year, and it worked well, but then the app seems broken to extend it (I.e. I click to pay and extend but it says “failed try again”) - I sent a message in chat support but it was ignored, and have tried over several different days / changed payment method in App Store. Nothing working So now I will delete the app and get a different one.

### 1/5 — DO NOT PAY FOR THIS

*2026-03-15*

App is deeply floored and riddled with bugs. And there is zero help. The builders have abandoned it. Should not be on the App Store. Money lost. Apple - you should be getting me my money back.

### 4/5 — Great app but need to key in 12 month

*2026-02-01*

I like the app very much especially because I’m a frequent traveler.  Why can’t I type in Jan 1 2026 to Jan 31 2026.  I have to go in daily to update the days.  Not a good feature

### 1/5 — Immediately bombards you with spam

*2026-01-01*

I do not think I have ever installed an app that sent more aggressive spam notifications than this one. Trying to upsell me almost from the minute I installed it. I turned off notifications, but then the app stopped working altogether. Totally useless, deleted the app.
