### 1/5 — Пропала возможность встроенного gps в телефоне

*2024-07-04, version 2.2.0*

Очень жаль что теперь нельзя со встроенного

### 1/5 — Too slow

*2023-09-13*

Way too slow to record anything. Maybe if you drive a prius it might work.

**Developer response:** We have removed regular GPS support because it is not precise enough. Now we have our own external GPS device on sale with the best precision in the market, so we suggest using one. Also, app support few other manufactures like: Dragy, VBox Sport, Racebox.cc, and RaceHF.

### 1/5 — Useless

*2021-09-19*

App doesn’t work. Closes itself when you connect to iphone gps.

**Developer response:** Bugs regarding native GPS are fixed, please check again. Anyway, we highly suggest using external GPS device if you want to have any usefull data. iPhone GPS support is there just an example, it is 1Hz and not nearly precise as external GPS devices.

Please test version 1.9.4 and consider updating your review 🫶

### 5/5 — Отличная программа.

*2020-12-31, version 1.7*

Очень хорошая программа с отличным функционалом, пользовал её в связке с RaceBox. Прошу сделать её платной с оплатой один раз и навсегда по подписке нет смысла её покупать 1500 рублей в год очень дорого при её использовании.

### 5/5 — Dobar

*2020-07-08*

Bravo majstore!

### 3/5 — 111

*2020-05-15, version 1.4*

Здравствуйте сделайте на русском меню а то на английском языке ничего не понимаю

### 5/5 — Better than vBox app!

*2019-07-26*

Great app that can measure acceleration, distance and stuff like that. It can measure with your mobile phone gps or with vBox racelogic which is best option. 
Also it can make video of your run with telemetry overlay. 
Huge recommendation!
