Negative review about the app:
1)It seems some sounds are missing in the chart like:
short e sound
ar sound
or sound.
The chart is very confusing because of missing sounds in the chart
If short e sound is in there and then the notation of one of the sound is incorrect making another sound missing in the chart.
2) Once the app is paid for $5, pay $1 for every wordlists. There might 5 to 10 other wordlists bringing the app cost to $20. The business model of bring in the money has completely outweighed the noble cause of app to teach and learn.
3) The chart takes long time to open.
Positive review about the app: The app is well organized, way better than most when it comes to practice and quiz. Hardly seen anyone offering practice and quiz for pronunciation of sounds.
Conclusion: Personally , I wouldnt buy it if I knew the faults, unless the wordlists comes in a one time payment package with free update of app and wordlists.
