You can debate whether the app is worth it, but the bottom line is
that the price increase is huge in percentage terms.
TextExpander 4 was $35 in 2012, and there was a $20 update for
TextExpander 5 in May of 2015, about three years later. Now, after
less than a year, the price for a yearly subscription is $47.52.
(There is a one-time, one-year 50% discount for previous
customers.) So the price for three years has gone from $20 to
$142.56. I have paid for a lot of apps recently, and the only
ones that are in that price range are Microsoft Office, Adobe
Lightroom, and TurboTax. TextExpander is a great app, but it just
doesn’t feel like it’s in that league.
With Microsoft and Adobe, it takes multiple years of subscription
payments to equal the previous single payment. So it was more a
change in payment model than an increase in price. And the
subscription offered the benefit of never having to suddenly make
a large payment.
