## SkewTLogPro Reviews in United States

### *---- "No longer works unless you subscribe"
I agree with the other comments form others.  This product suddenly now requires a subscription.  No warning or anything.  No option to verify if it even works now.  Good bye!
-- BBCcricketFan, 2025-06-14

### *---- "Paid app that worked for years suddenly requires subscription"
Paid for the app several years ago. Now with the update, my purchase is basically useless because now I have to pay a subscription to use the app. No option for existing users. Legacy users deserve a refund if there won’t be an exception made for them.
-- Kyle0440, 2025-06-08

### *---- "Paid Users Held Hostage by Surprise Subscription"
I paid a premium price for SkewTLogPro expecting a full-featured, one-time purchase. After the latest update (v3.3) the app now locks me out unless I cough up a recurring $13/year subscription—and that major change wasn’t mentioned anywhere in the release notes.

No “legacy user” option, no warning, just pay again or lose access. That’s an unethical bait-and-switch, plain and simple. I’m furious that my original purchase has effectively been voided. Apple: please investigate, and developer: honor the licenses you already sold.
-- Andreasa4, 2025-05-04

### *---- "Used to be the best, not anymore"
I am a CFI who USED to use this app daily for summer flying & recommended it to all my colleagues and students. No more. Why? Well, while pricy to initially acquire, this app USED to be a one-time fee ($12 I believe). Then it inexplicably broke for the past year when the FAA/NOAA changed their data API, crashing when I tried to load the chart for any field. The developer provided no responses to my bug reports, despite my being an avid user and advocate. So. I gave up on this app and instead started using Windy’s skew-t generator, which is free. As this summer has rolled around, I noticed an update was FINALLY released. I excitedly downloaded it and — SURPRISE — the app been paywalled behind an annual subscription! No demo mode to verify that it actually works. No regard for the fact that I ALREADY paid to acquire it. Regrettably there are plenty of free Skew-T generators out there so I am removing this from my EFB and will no longer mention it to colleagues nor students. It’s been a nice run folks, sorry to see that this IP has been sucked up by a faceless corp who just want to extract an annuity from pilots and has no regard for prior purchases. To add insult to injury, the underlying data source (NOAA) is STILL paid for by US tax dollars. Shameful.
-- Riccola Popcorn, 2025-05-03

### *---- "Unethical developer!"
Paid a flat price for the app, $15 as I recall. But now on the last update it turned into an annual subscription. Unethical developer!
-- swtbby, 2025-05-01

### *---- "Greedy developer bait and switch"
I bought this app pre-subscription for a hefty price. Now, it has zero functionality and attempts to extort another $13/year out of me.
-- dstites, 2025-04-14

### *---- "Bait and Switch"
Bought a year ago and upon opening it suddenly it demands a yearly subscription. Try tropical tidbits or windy, they have free skew t information. This isn’t it for me anymore ;-;
-- NeoshadowVen, 2025-03-17

### *---- "Poor execution, jacking buyers for subscriptions"
Bought this a couple years ago. It’s really not worth buying, as 1. It crashes repeatedly, and 2. They charged a pretty hefty amount up front, then added an annual subscription fee after the fact.  There are online tools that are more reliable, and free.  Use flytheweather.com, it’s free and better.
-- TMD55c, 2025-03-15

### *---- "Too Expensive!!"
Like many other reviewers, I purchased this app years ago then got locked out requiring $13 per year for something we can get online in many locations for free.  GREED is ugly!!!!!!   Maybe $6 a year is worth it. Will be waiting until hopefully the price is lowered.
-- SAP0570, 2025-03-13

### *---- "Purchased the app but now I’m locked out???"
Spent money on this app and found it very useful. Then it went offline with no notice or communication. Now, it’s back but I need a subscription and I get no credit for having purchased it in the first place?? Very poor customer service. The developers need to make this right.
