The latest "smart" messaging app from Google dubbed Allo is finding favor with Android users and has notched up a whopping 5 million downloads on the Play Store in just a week since it was made available.

The 5 million downloads for Allo is only for Android, which if combined with the installations for iOS could result in a higher number.

Earlier on Sept. 24, we reported that Google's Allo app had hit the milestone of 1 million downloads in the Google Play Store as users hurried to download the latest messaging app with nifty features despite privacy concerns.

The milestone made Allo a part of the million downloads club, joining the ranks of video messaging app Google Duo, which was released in August and has raked in over 10 million downloads.

The popularity of Allo is evidenced by the fact that it was the top free Android application in the United States over the last weekend.

Five million installations in barely a week of release is impressive to say the least and could perhaps be a sign of good things to come. However, the million dollar question is: can Allo sustain this growth or the spike in downloads is just a flash in the pan?

The fact that Allo ranked number one in the Top Charts on the Play Store five days ago —and is now sitting pretty at number eight— is reflective of the fact that perhaps it was anticipation and excitement for the messaging app that fueled users to download the smart messaging mobile app.

Interestingly, the fast growth and declining interest pattern for Allo is comparable to that of Google Duo. When the video messaging app from google launched, it quickly captured the number one spot in just two days of the rollout. In a matter of nine days, Google Duo had amassed 5 million downloads. Allo, on the other hand, also took two days to climb to the number one rank on the Play Store. However, it reached the magical 5 million downloads mark in seven days instead of nine.

If this trend is anything to go on, then by the time Allo attains 10 million downloads like Google Duo, it would have slipped to number 127 on the Top Charts.

While users may be pleased with Google Assistant's inclusion in Allo, making it a smarter messaging app, the privacy concerns (as highlighted by NSA whistleblower Edward Snowden) could overshadow its popularity in the long term.

Moreover, considering Allo is already number eight on the Top Charts in five days, the future doesn't look too bright for the Google messaging app. If you wish to add to the five million downloads, you can get Allo from the Play Store.
