You need an account first. The app does nothing without a login, and logins are created by your organisation's iChek administrator. If you do not have one, ask your coordinator. Install the app only from this page or from a link your coordinator sends you.
पहले आपका अकाउंट होना ज़रूरी है। बिना लॉगिन के ऐप कुछ नहीं करता, और लॉगिन आपकी संस्था के iChek एडमिन बनाते हैं। न हो तो अपने कोऑर्डिनेटर से माँगिए। ऐप सिर्फ़ इसी पेज से या कोऑर्डिनेटर के भेजे लिंक से लगाइए।
How to install it
On your phone, open this page in Chrome and tap Download the app.
If Chrome says "This type of file can harm your device", tap Download anyway. That message appears for every app that is not from the Play Store.
When the download finishes, tap Open (or find ichek-field in your Downloads).
If Android says it cannot install apps from this source, tap Settings, switch on Allow from this source, press back, and tap Install.
If Google Play Protect shows a warning, tap More details, then Install anyway.
Open iChek Field. Allow Camera and Location when asked, then sign in.
After installing you can switch "Allow from this source" off again.
Good to know
Updates: when a new version is ready the app tells you. Tap Update, then Install.
New phone: your account is tied to one phone. Ask your coordinator to release it, then install and sign in on the new one.
Photos are taken inside the app only, and your location is recorded with each one.
iPhone: there is no iPhone app. Open av-app.ichek.info in Safari and use Share → Add to Home Screen.
