One hour of measuring free
License
Try an hour.
Then it is yours.
Signal Collector installs from Google Play and can do everything from the start: every source, every interval, export and delivery to your own server. The only thing counted is measuring time — one hour per year is free. When it runs out, a single purchase inside the app brings measuring back, for good and without a subscription.
What is free
The trial is not a stripped-down app. It is the full app with a meter on measuring time: 60 minutes per 365 days. The period starts with your first measurement, not with the install.
- Only a running measurement is counted. Configuring, browsing, exporting and delivery are not.
- Every source is available from the start — raw GNSS, LTE and 5G cells, Wi‑Fi including RTT, Bluetooth, sensors and real throughput tests.
- If the trial runs out mid-measurement, the app stops the measurement but everything collected stays saved and can still be exported and delivered.
What unlocking changes
It removes the time limit. Nothing else changes, because nothing else is limited in the trial.
- It lasts. One payment, no subscription and no expiry date. Updates from the store are included.
- It follows the account, not the phone. Sign in to a new device with the same Google account and it is unlocked there too.
- It keeps working out of signal. The app remembers the purchase itself, so a phone deep in a building or far from a mast keeps measuring.
- It says nothing about you. Unlocking creates no account of ours and asks for no name, e-mail or device identifier.
Price
Unlocking is a one-off in-app purchase. Google Play shows the price in your own currency, with your country’s tax already in it — which is why no figure is printed here: a number in euros would be the wrong number for most of the people reading this page.
The price is higher than a monthly subscription would look, and that is the point. You pay once and the tool is yours; there is no date on which measuring stops working because a renewal did not go through — and out in the field, that matters more than the sticker.
The app carries no advertising and no analytics, and the measured data is never anyone’s to sell. The price is what pays for the development instead.
How to buy
Everything happens inside the app, in Google Play’s own payment sheet — there is nothing to order by e-mail and no code to copy anywhere.
- Install the app and measure. The remaining free time sits right above the Start button.
- Tap Unlock there, or wait for the offer when the free hour runs out.
- Confirm the purchase in the Google Play sheet. Measuring is unlimited from that moment.
Already bought it and installed the app on another phone? It unlocks itself as soon as Google Play confirms the purchase for your account — there is nothing to enter.
The app is operated by Indigo Studio. How it handles measured data is described in the privacy policy.
