Organiser

Survey link

Paste your Google Form link (the edit link is fine). Testers see it on the home screen, after they answer “Did you order?”, and in the footer. Their anonymous participant code is filled in automatically.

Testers who tap “Turn on” in the app get three alerts a day at random times between 9 am and 10 pm (IST), well spaced out, plus one “Back from Blinkit? Upload your bill” reminder 30–45 minutes after they open a shopping app from RightCart (at most one every 3 hours, skipped if they already reported the order). Some are real price gaps near them, from prices already checked, so no extra credits are used. Messages are in push_messages.json.

Invite testers

Each person gets their own code, so their data stays separate and anonymous (they appear as a participant number).

Share one code with all early-access users. Each person who signs in with it gets their own anonymous participant number. Testers never see organiser pages or credits.

To change the code or the daily limit, set TESTER_CODE or SHARED_DAILY_SEARCH_LIMIT in Render → Environment. Changing the code signs out everyone who used the old one.

Delivery and other fees for everyone

The apps don't publish their fees, so enter what their checkout shows today. Every tester's totals then include them, and the best plan only suggests splitting an order when it saves more than the extra fees. Testers can still change them for themselves, and their offer screenshots replace these with their own.

Add a missing locality

Testers can search about 6,000 localities across Delhi NCR, the Chandigarh Tricity, Mumbai, Bengaluru and Chennai, but some colonies (for example in Sonipat) aren't on free maps. To add one: in Google Maps, press and hold the place, copy the numbers shown (like 28.9931, 77.0151) or the place's link, and paste them here. Every tester can then find it by name.

Research data

All times are India Standard Time (IST). Testers appear only as participant codes (P-…), and locations as the nearest area.
