### 1/5 — Can’t even use app bc doesn’t connec

*2026-08-09*

Very frustrating because you cannot use the app offline and when you try to use it and you are online, it says it can’t connect to Dogl, so you can’t even do a single problem. Maybe this app is abandoned.

### 5/5 — Student

*2026-07-08*

Thank you.

### 5/5 — please finish under construction topics!

*2026-06-04*

love the app! willing to pay more for the rest of the under construction topics to be done asap. the format is so much better than brilliant and the quiz style is really helpful. would love to be able to review everything I am learning and not just the limited topics dogl has material for. thank you devs keep up the good work

### 3/5 — Convenience is nice, leave me with wanting more

*2025-10-17*

The ability to do a lot of problem on the couch laying in bed is really nice but they don’t actually teach you any topics just provides practice problems. I think they can add teaching segments and a lot more data about performance in certain topics

**Developer response:** Thanks for the feedback! The app is built for practice, not teaching, so for notes and definitions we recommend using a textbook, like OpenStax, or a resource like Paul's Online Math Notes. If you don't want to follow a particular textbook, consider choosing Dogl Special Blend. Better data is on our roadmap!

### 5/5 — Best educational app out there

*2025-08-11*

This is a stellar app for learning and reviewing math and calculus. You can tell it was created by educators and designed to teach you calculus in a way that slowly builds skills and introduces new content in a controlled and digestible way. I love that the problems often give you the context that you need and assume you haven’t had any experience, and the hints are phenomenal at pointing you in the right direction without giving the answers away.

### 5/5 — Best app from zero based

*2025-07-01, version 1.1.26*

If you have calculus next year or doing it buy the 4 month!!!! I bought the one year but this turns calculus into a game who ever the dev is thank you so much for creating this life changing

### 1/5 — Careful

*2025-06-18, version 1.1.26*

Locks up iPhone

### 5/5 — App is fantastic

*2025-04-16*

Just what I was looking for and needing. Thank you so much for developing this and making it free. Math requires practice and this helps me build and maintain my knowledge.

### 5/5 — Beautiful Free math

*2025-03-25*

lovely app, very clever and a super fun easy way to work on intuition and bolster your understanding calculus

### 5/5 — Great for Calc I-II

*2025-03-08*

I really enjoyed Dogl, I only wish it extended beyond Calc I-II. Tried this while in a 6 week Calc II winter semester—was a nice way to exercise skills. (If only it offered into Multi-Variable and beyond…)
