The OSTEO-GAINS Bone Health Program Year One costs US$24.99 for 12-months access. No free trial is offered with the Bone Health Program. Once you download and register for the App, you get FREE access to the Pre-Conditioning Program and FREE access to the Stretching Program. Future access, e.g., Bone Health Year One or Bone Health Year Two, will require manual separate payments of US$24.99 for Year One or $28.99 for Year Two. Subscriptions do not auto-renew annually. ONE: Prepare Start with our OSTEO-GAINS Pre-Conditioning Program for the first 4 weeks. You will repeat each session (approximately 23-24.5 minutes) 3 times each week to get your body ready for the OSTEO-GAINS Bone Health Program. Complete the 12 sessions over one month before purchasing the OSTEO-GAINS Bone Health Program. TWO: Stretch Perform the OSTEO-GAINS Stretching Program (approximately 14-14.5 minutes) after every Pre-Conditioning session to help your muscles recover, or use the Stretching Program as often as you like. THREE: Perform The OSTEO-GAINS Bone Health Program Year One is performed barefooted on a firm and forgiving surface, such as carpet, grass, wooden floors or sand and works in 4-week blocks. You repeat the same session for 4 weeks before progressing to the next new 4-week block. The OSTEO-GAINS Bone Health Program Year One is designed to be progressive and repetitive. This program includes osteogenic exercises that take approximately 3-5 minutes a day, and you can do them in the comfort of your own home ... while you wait for the kettle to boil. In the OSTEO-GAINS Bone Health Program Year One, you will be guided through a structured exercise program that becomes progressively more difficult over 12-months. In the Bone Health Program Year One, you will 'Jump, Jump, Rest, Repeat' to strengthen your bones 2-5 times each week, using a series of specific jumps and jump-landings. Our research found that bone health in premenopausal women improved (3.5 to 5% at the end of 12-months) when they performed the exercises, taking only 3-5 minutes a day. Our research informed how we structured our 12-month OSTEO-GAINS Bone Health Program Year One. We measured improved compliance and technique, which led to significant lower body bone health improvements in our research participants. The OSTEO-GAINS Bone Health Programs are a supplementary osteogenic exercise program to specifically target bone health and can be performed alongside your regular exercise programs. PROGRESS Keep track of your landings/impacts progress over 52 weeks. DEXA Scan We recommend, where possible, getting a DEXA scan done before you start our OSTEO-GAINS Bone Health Program Year One. This will provide a benchmark measure of your current bone health and the ability to track any changes in your bone health over time.

Verdict

The call

The clearest difference is rating: SH1FT at 4.9 against OSTEO's 2.4. SH1FT also leads on in-app purchases (none vs 3). OSTEO's advantage is review sentiment (36% vs 20%) and update cadence (every 8 days vs every 3 weeks). On price, ads, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

SH1FT holds the better App Store score, 4.9 against 2.4. That said, the two scores are not equally well evidenced: OSTEO has 48 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 20% of SH1FT's written reviews are positive against 36% of OSTEO's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

SH1FT ships an update every 3 weeks, OSTEO every 8 days. The most recent releases landed on October 24, 2026 and October 22, 2026 respectively.
