### 1/5 — Rip Off

*2021-03-15*

Initially purchased app for $2.99, opened app and was learning the creations patterns. Tried to move on to next set of patterns, additional $1.99 required. I thought after two payments i unlocked everything, only to discover an additional $1.99 required for the next set. This doesn’t provide code, nor visual aids so why charge so much just for abstract descriptions and practice tests that don’t even display correctly. Be honest up front on the ALL costs
