### 1/5 — Widget Broken

*2026-07-23*

The Home Screen widget shows the daily catechism question, but the text color is barely distinguishable from the background (dark gray on black) — completely unreadable regardless of whether the phone is in Light or Dark mode. This isn’t a system dark-mode contrast issue; the widget text stays the same dark color in both modes.

Also noticed the widget/app doesn’t respond to switching Light/Dark mode live — it only picks up the change after a full reinstall, and even then the widget’s text color doesn’t improve either way.

There’s no setting inside the app or the widget itself to change text color, theme, or contrast for the widget specifically. Would love to see this fixed — the daily question widget is the main reason I use this app, but right now it’s non-functional.

Great app otherwise and thanks for building it.

### 5/5 — Best way for a daily reminder to study both the Catechisms and the Bible.

*2026-04-22*

It helps to keep me focused on biblical standards and by using the references it helps me to better understand what the Bible is saying.

### 5/5 — Excellent!

*2026-03-09, version 3.1.0*

My favorite catechism app!

### 5/5 — Mr

*2025-11-14, version 3.0.0*

What a great way to review these teachings! Thanks

### 5/5 — Great review

*2024-11-04, version 3.0.0*

I enjoy getting a daily reminder of Biblical theology right to my phone! Love it

### 5/5 — Perfection

*2024-10-20, version 3.0.0*

This app has helped me understand the Bible, Christin life and God so much.

### 5/5 — Good but could be great

*2024-01-01*

Love the variety and simplicity.  I think it would be better if we could copy the scripture texts though to allow for some consideration and study.  In any event the app is great I use it, great way to think of heavenly things in the day.  Also because it reminds me! Thanks Catechism team! 😉

**Developer response:** Thanks for the suggestion, and the kind words!

### 5/5 — Top notch

*2023-09-17*

My daily go-to catechism app. It’s the cleanest and neatest looking of all the Reformed catechism apps, and its option for daily Q/As, clear or blurred-out answers, and audio give it a superior edge.

**Developer response:** Thank you for these encouraging words!

### 5/5 — Excellent help. Very usable.

*2023-08-19*

Using this with my two boys (8 and 5), and it’s a very easy way of practicing the shorter catechism. Very cool feature that lets you blur the answer while looking at the question, and then simply tap the screen to show the full answer. I also LOVE that it has not only Scripture references for each Q&A but it provides the full text of each reference right there below the answer. It’s vital to me that I help my kids see how each of these answers is derived directly from numerous portions of Scripture. And this feature makes it REALLY easy to immediately do that for each question/answer.

### 5/5 — James

Thanks be o God.
